Abstract

This project was proposed as a technology development and testing project to evaluate an innovative

extended aerated static pile (eASP) compost system design at commercial scale.  The purpose was to

determine whether the innovative design could produce compost of acceptable quality while reducing

air emissions.  The eASP was compared to standard windrow composting conducted at the same facility

using the same feedstock.  The eASP was tested in a single selected configuration; therefore, the results

of this project do not establish optimal operational parameters, such as blower speeds or water

application rates, but results are sufficient to establish proof of concept.  

A prototype commercial‐scale Aerated Static Pile (ASP) compost system was built using electric

conveyors in place of diesel trucks and loaders. Three ASPs were built abutting each other to create an

extended design which we define as an eASP.  The eASP piles were deeper and wider than a typical

windrow, were placed on a foundation of aeration tubing and chipped material, and were capped with a

1‐foot‐thick layer of finished, unscreened compost acting as a biofilter layer or “compost cap.”  The

three static piles of the eASP were aerated using power provided by an on‐site photovoltaic array.  The

intent of this design was to take advantage of emissions reductions previously demonstrated by

biofilters and ASPs with a design footprint more similar to existing windrow methods.

Windrows of identical greenwaste feedstock and of industry typical dimensions were created nearby

with a loader and turned with a diesel‐powered mechanical turner, which is the normal method of

composting in much of the United States.  No biofilter caps were applied to the windrow, as that is not

the normal practice at this facility, nor is it required by air district regulation.

A series of three ASP zones and three windrows were built approximately one week apart.  This allowed

the in‐the‐field measurement period to be shorter while still collecting measurements representative of

the full 22 day active composting period.   Emissions of VOCs, ammonia and greenhouse gases from both

sets of piles were sampled using the USEPA‐approved flux chamber method, as modified for composting

emissions by the South Coast Air Quality Management District.  Emissions reductions from reduced

diesel use were calculated by using the estimated time necessary to accomplish standard tasks,

multiplied by the allowable tailpipe emissions for equipment normally found at commercial scale

composting sites, such as trucks and loaders.  

The comparison of emissions from the 22‐day active composting phase between the eASP and standard

windrows demonstrated emissions reductions by the eASP of 99% for total non‐methane, non‐ethane

VOCs, 70% for ammonia (average of field and lab), 88% for nitrous oxide, and 13% for methane.  The

overall reduction for CO2 equivalents was nearly 65%. Diesel use in pile construction and active‐phase

management was 87% less for the eASP system, with commensurate reductions in criteria pollutant

emissions associated with diesel fuel combustion.  Water used during the composting process was

reduced by 20%, and land necessary for active‐phase composting is calculated to be reduced by 55.5%.

Samples of finished compost at 30 days of composting  from the eASP and standard windrows  were

sent to an accredited laboratory for industry‐standard testing.  Maturity and stability of the eASP

materials were equal to or better than their windrow counterparts.

Executive Summary

A prototype extended Aerated Static Pile (eASP) composting process was assembled and operated to

test both ability to produce quality compost and to quantify air emissions.   EASP differ from ASP only in

that consecutive zones are laid alongside each other along the long axis.  The eASP utilized ambient air

blown into the pile from the bottom; the blowers were powered by photovoltaic panels and associated

batteries. The eASP had a biofiltration layer added to the surface as an air pollution control measure.  A

series of compost windrows were built concurrent with the eASP using the same feedstock.  The air

emissions from the eASP were compared to the on‐site measured air emissions of the current industry‐

standard windrow composting method.   

Emissions were measured using the standard methods and techniques used for San Joaquin Valley Air

Pollution Control District (SJVAPCD) regulatory compliance.  This includes the use of the USEPA flux
4 | Page

chamber as modified under South Coast Air Quality Management District (SCAQMD) Rule 1133, and

analysis using SCAQMD Method 25.3 and 207.1.  In addition to these traditional methods, nitrous oxide

(N2O) was measured using NIOSH 6600 and organic species were measured using USEPA TO‐15.

Table ES‐1 provides a summary of the emissions using the emission factor of pounds of pollutant

emitted per ton of compost mix in the pile or windrow over the 22‐day active composting period, as

specified by SJVUAPCD Rule 4566.  VOC reductions of 98.8% were achieved when compared to the

control windrows.  Reductions in ammonia emissions were 83% using tubes in the field, and 53% from

the laboratory, when the eASP was compared to the control windrows.  Reductions in emissions of

greenhouse gases ranged from 13% for methane up to nearly 89% for N2O for the eASP system when

compared to the controls.

Table ES‐1:  Results of emissions testing in pounds of pollutant per ton of feedstock over the 22‐day active

composting period.

To normalize the analysis of windrow (on‐site control) emissions being higher than expected, project

results were also compared to adopted emissions factors from the SJVUAPCD and the SCAQMD.

using eASP system compared to emissions factors adopted by SJVUAPCD and SCAQMD.

As with any composting emissions test, sampling opportunities seem limited when compared to the vast

size of the composting piles and the time necessary to complete the composting process.  A total of 92

samples were taken, including 84 samples and 8 quality control blanks.  Sampling during the composting

cycle ranged from day 3‐to‐day 23 for the eASP and day 2‐to‐day 29 for control windrows.  For the eASP,

pre‐planned sampling locations were demarcated on top of all three zones to ensure those locations

were neither walked upon nor perforated with the temperature probe.   Because each sampling event

takes approximately two hours, and the eASP blowers were set to operate two minutes out of every 20,

eASP sampling included multiple blower‐on and blower‐off cycle conditions.

An additional sample was taken of a 63‐day‐old windrow.  It was later revealed that this windrow

contained a significant amount of food waste.  Those data are reported in the appendices.

22‐day emissions were graphed to look for differences in air emission for key target species over the

composting cycle.  Total non‐methane non‐ethane organic carbon emissions for the control windrows

followed established trends; an initial spike followed by rapid decline.  The eASP emissions line is nearly

flat.  Methane emissions from both the eASP and the windrow are greatest toward the middle of the

active compost period, while N20 emissions from both piles tend to increase toward the end.

important greenhouse gas with a climate warming potential no less than 21 times greater than carbon dioxide.

is an important greenhouse gas with a climate warming potential no less than 298 times greater than carbon dioxide.

Total emissions and emissions per ton of feedstock were also calculated for 30‐day and 60‐day cycles.  

60‐day results for the eASP are necessarily extrapolated beyond day 23.  30‐day totals require much less

extrapolation.  A complete accounting for all emissions testing is reported in Appendices A and B.  In

general, the longer calculation periods show greater benefits from using the eASP, particularly with

regard to methane; VOC reduction benefits are virtually unchanged.  These calculations and graphs are

available in Appendix A.

Reductions in diesel use were calculated for pile construction and management during the active phase.  

For windrows this includes mechanized turning, but the eASP was not turned for the first 30 days.  The

overall reduction in diesel use was 87%.  A commensurate 87% reduction in criteria pollutants from

diesel emissions was also calculated.  These data and calculations are discussed further in the body of

the report as well as in Appendix C.

Water use reductions were also calculated.  The initial watering of ASP feedstock and 30‐days of timed

sprinkling of the eASPs used approximately 20 percent less water than the traditional windrows, which

were watered by a 4,000‐gallon watering truck with a sprayer on the back.  For a theoretical 100,000 ton

per year facility, this would save about one million gallons of water per year, with commensurate GHG

reductions from eliminating the water truck fuel use.  These calculations are discussed in the body of the

report.

EASP piles can be built wider and taller than windrows, which can be no larger than the largest windrow

turning machine on site.  This gives the piles a smaller surface area, potentially reducing both

evaporation and emissions.  Larger piles can also reduce the amount of land needed for a composting

operation, thereby reducing costs to purchase land or to build working pads.  For active composting, we

calculate the EASP system can accommodate approximately 3,552 tons of material per acre, while a

typical windrow system would handle around 1,580 tons per acre, an advantage of 55% for the eASP.

Introduction

The San Joaquin Valley (SJV) is an extreme non‐attainment area for ground‐level ozone, according to the

United States Clean Air Act 8‐hour ozone standard.  Air quality officials in the SJV must reduce ozone

precursors such as Volatile Organic Compounds (VOCs) and oxides of Nitrogen (NOx) as expeditiously as

practical, as technologically feasible, and as economically reasonable.  The SJV is home to numerous

commercial‐scale composting facilities that process urban organic wastes, including several that handle

more than 100,000 tons of feedstock per year and one that handles more than 500,000 tons annually.  

Two large facilities import compostable feedstock from other air basins, including Los Angeles to the

south and the San Francisco Bay Area, to the northwest.  Because the SJV contains extensive agricultural

operations, a local market exists for the finished compost products. The finished compost products are

applied to farm fields generally less than 25 miles from the composting site, providing a source of

nutrients and organic matter for SJV farmers and nourishing some of the most productive farmland on

Earth.  
7 | Page

During the natural process of organic degradation, compost piles emit VOCs.  The SJV has a large

inventory of man‐made and natural VOCs and a much smaller inventory of NOx emissions. Ozone

production in the SJV is considered “NOx limited” because of the lesser amount of NOx.  Internal

combustion engines, including heavy duty diesel engines, are the SJV’s primary source of NOx.   When

mixed with VOCs, NOx forms ground level ozone, particularly in the presence of the strong sunlight

which blankets the SJV more than 300 days a year.

To facilitate a regional approach to air pollution problems, seven California Counties and part of an

eighth county joined to form the San Joaquin Valley Unified Air Pollution Control District (the District),

which covers more than 25,000 square miles from Stockton to Bakersfield.  In 2011, the District adopted

Rule 4566, which seeks to reduce emissions from commercial composting facilities.  Existing composting

facilities in the SJV were required to adopt a series of Best Management Practices which are scaled

based on a facility’s annual throughput.  

Because it is an extreme non‐attainment area for ozone, any new facility in the SJV emitting more than

10 tons of VOC per year is classified as a Major Stationary Source.  Using the SJV’s life‐cycle composting

emissions factor of 5.71 pounds of VOCs per ton of composting feedstock, a facility handling less than

4,000 tons per year would be considered a Major Stationary Source.  Per Title 1 of the Federal Clean Air

Act, all new major sources must go through New Source Review in order to be permitted to operate.  

This means that all new composting facilities in the SJV must implement Best Available Control

Technologies (BACT) that reduce VOC emissions from materials handling and the composting process.  

BACT specifications for new compost facilities have not yet been determined.  The impact of New Source

Review has been to stifle the growth of new composting facilities in the SJV, as the current cost of VOC

reduction systems exceeds the ability to recoup those costs through tipping fees and finished product

sales.   Composting facilities cannot raise tipping fees without losing feedstock to lower‐cost

alternatives, such as landfilling or direct land application.

In 2011, the California Legislature passed AB 341 (Chapter 476, statutes of 2011), which requires the

State to achieve a 75% solid waste recycling, composting and reuse rate by 2020.  The California

Department of Resources Recycling and Recovery (CalRecycle) is charged with coordinating efforts to

reach that goal.  According to CalRecycle, organic materials‐‐in particular food‐‐comprise up to 50% of

the remaining disposed waste stream.  Therefore, the 75% goal will not be attainable without more

composting facilities.

Large facilities in the SJV and around North America manage materials in windrows: long, narrow piles

that can be as much as 20 feet wide, 8 feet tall, and hundreds or even more than 1000 feet long.  

Windrows are turned using a specialized machine called a windrow turner, which straddles the pile; the

exact height and width of the windrows are determined by the size of the turning machine.  All windrow

turning machines are powered by diesel engines, with 450‐600 horsepower being typical engine sizes for

moderate to large machines.  Generally, piles are built using diesel trucks and bucket loaders.

According to California regulation (14 CCR, Section 17868.3), compost piles must reach a temperature of

131 degrees Fahrenheit in order to reduce pathogens.  Windrows must maintain that temperature for
8 | Page

15 days, during which the pile must be turned at least five times in order to ensure all materials in the

windrow reach temperature.  Static piles with an insulation layer at least 6 inches thick only need to

attain that temperature for three days.  Although attainment of pathogen destruction may occur any

time during the composting process, it typically occurs early in the cycle, to ensure feedstocks have

sufficient energy to meet the temperatures requirement.  Most operators report turning piles 8‐10

times during a complete compost process of between 60 to 90 days.  Previous research indicates that

the vast majority of composting emissions occur during the first three weeks of the composting process,

hence the focus on “active phase” composting in Rule 4566 and in this research project.  Per Rule 4566,

several SJV compost facilities are required to put a fresh blanket of finished compost on top of a

windrow following all turns during the first 22 days.  Compost caps are effective on windrows, but

applying so many caps is both labor and diesel intensive.

The Technology Advancement Program

The TAP program is administered by the San Joaquin Valleywide Air Pollution Study Agency (the Study

Agency), which was “formed to commission and administer scientifically sound air quality studies to

improve understanding of the contributing factors and conditions that result in poor air quality in our

local area and in the surrounding areas of central California and to develop technical tools for use by

decision makers to guide the development of policies, procedures, plans, rules and regulations

necessary to fulfill the state and federal air quality mandates.”  The Study Agency is a Joint Powers

Authority with its fiscal authority vested in a governing board.    

In 2011 the Study Agency put out a Request for Proposals for the Technology Advancement Program

with the objective to “demonstrate new and innovative emission reduction technologies that have the

potential for broad applicability in the San Joaquin Valley.” A portion of the available funding comes

from collaboration with the USEPA’s Clean Air Technology Initiative.

Specifically, the RFP sought “projects that demonstrate bold, innovative, and creative new emission

reduction technologies” in three areas, renewable energy, waste solutions and mobile sources.  The

accepted proposal met all three criteria in the following ways:

 Focus Area I: Renewable Energy—This demonstration project proposed to overcome the barrier

to utilizing renewable energy by installing solar energy/storage systems to power air blower

motors to be used to aerate static compost piles, and to maintain aeration throughout the high‐

emissions active‐composting phase.

 Focus Area II: Waste Solutions—Project used technology which had not been operationally

demonstrated on a commercial scale, to minimize VOC and GHG emissions from existing

compost production systems and processes. This technology was non‐proprietary and created

with components which should be available to any compost operator, thereby reducing costs of

emissions reductions.

 Focus Area III: Mobile Sources—Project demonstrated the replacement of large diesel‐powered

compost loaders with electric powered conveyors, and demonstrated replacing diesel‐powered
9 | Page

composting windrow turners with solar powered air blowers to reduce particulate matter and

NOX emissions from those sources on compost operations in the San Joaquin Valley.

This project included construction of three abutted aerated static piles, each with its own aeration

manifold and photovoltaic powered blower.  This type of ASP System is referred to as an Extended

Aerated Static Pile (eASP). In addition to the expected air emissions benefits and reducing the use of

diesel power during the composting process, three key benefits of this approach include: 1) smaller foot‐

print and therefore a greater production capacity for a given compost pad; 2) reduced exposure to the

elements; and 3) improved retention of process heat.   

Project Components

Conveyorization of the construction of the eASP

Construction of windrows or static compost piles is traditionally done with diesel truck and loaders.

We built the eASP using electric‐powered conveyors.  The heart of the system was an electric‐powered

potato piler.  Pilers are used for placing harvested potatoes into storage sheds.  This potato piler had the

ability to move the terminal end of the conveyor left and right up to 57 feet, as well as up and down

approximately 27 feet.  The terminal end of the piler also telescopes up to 18 feet.  These maneuvers

are accomplished using a remote joystick, much like a video game.  This adaptability allows for the

anchoring of one end of the piler, and connection to intermediate conveyors, while constructing a pile

which was up to 35 feet wide and as much as 10 feet tall.    It also allows for the feedstock to be

switched after the base pile is formed, to allow for application of the one‐foot‐thick pseudo‐biofilter

compost cap made from finished, unscreened compost atop the entire surface of the previously

constructed pile.

The potato piler is on wheels, and the spacing of those wheels allows for the pile to be set up within the

aeration piping for the pile, and wheeled backward when needed, along with the rest of the electric

conveyor train.  The 90‐foot‐long eASP zones were constructed in three stages of about 30’ each, then

the conveyor train was rolled backward and the process of constructing the pile and placing the cap

layer began anew.

The potato piler used in this experiment (Double L Manufacturing, Model 811) was smaller than some

models used in the potato industry.  The belt width was 30 inches and the rated capacity was 225 tons

per hour.  A commercial composting set up would likely use the largest available model, with a belt

width of 42 inches. If the methodology described in this report were widely adopted, manufacturers of

potato pilers might be persuaded to create composting‐specific machines, which might feature larger

wheels, wider belts, higher throughputs, and built in water sprayers at the terminus to ensure materials

are properly moistened during pile construction.  The smaller device was the only unit available locally

for rent, because potatoes are not an important crop in the SJV.  Larger devices would have needed to

be shipped down from potato growing regions, and shipped back in time for the fall harvest, an added

expense and constraint.

aeration pipes are partially visible.

One problem encountered early on was the ability to match the output of the grinder with the capacity

of the conveyance system.  In a professionally engineered system, these would be balanced.  In this

case, the conveyors and potato piler were smaller than optimal.  In addition, the existing on‐site grinder

at the Tulare compost site was designed for high‐volume throughput, and the output was not variable.  

It was clear that the available grinder would overwhelm the conveyors.  Because larger conveyors and

pilers were not available, a decision was made to rent a slow‐speed, variable output shredder.  Although

the shredder was able to keep a steady stream of materials on the conveyors, volume was slower than

ideal, and eASP construction took most of the day.

At 446 horsepower, the shredder has an engine half as large as the typical grinders found at large

composting sites.  This particular unit, the Komptech Crambo 5000, was certified ARB Tier 4.  The

variable output solved the problem of matching grinder output to conveyance.  Although there are

emissions savings from moving to a smaller horsepower engine, those are beyond the purview of this

project.  This would be a moot point in an operation that uses electric powered grinders.
11 | Page

Grinders are essential equipment at compost operations, and it was not a goal of this project to replace

the grinder.  The same slow‐speed shredder was used to prepare the feedstock for both the eASP and

the windrows.  Any composting operation that receives raw feedstock will still need to grind their

materials.  Electric grinders are becoming more commonplace, as greater emission reductions are

needed

Conveyors and the potato piler can run off whatever voltage is available on site.  480 volt AC power is

the most efficient and commonly used in potato storage and at compost facilities that have electrified

their grinders. In this case, the conveyors were run off a diesel‐powered generator.  In a permanent

setup, conveyors and pilers would be run off of the electric grid.  The generator was equipped with a

meter to measure electricity usage.

Also rented was an excavator to feed the shredder.  This could also have been accomplished with

loaders.  Although the excavator is a large piece of equipment, its engine is generally smaller than those

found in loaders.  This is because loaders drive to and fro, while excavators can stay in one place and

swing only their boom.   Again, there must be a means to move materials into the grinder/shredder.  It

was not a focus of this project to calculate emissions reductions from using an excavator for this

purpose, but it was an opportunity to model an optimum equipment configuration.

constructed hopper on the intermediate conveyor, and then is deposited into the hopper of the potato piler, center.  

From here the materials are carried upward and across the potato piler before being discharged at the far left,

Moisture management

Moisture management was another key challenge identified early in the process.  Because the eASP

would not be disturbed for the entire 22‐day active compost phase, there would be no way to deliver

moisture into the core of the pile.  Due to the action of the aeration system, as well as the hot and dry

summer SJV climate, water would be needed to prevent the drying out of the eASP, which could slow

the compost process or potentially lead to excessive heat buildup and fire.

An early idea to embed drip tape within the pile, just above the aeration pipes, was deemed unfeasible.  

Instead, a two‐pronged approach was taken.  The first phase was to wet all feedstocks during the eASP

build.  This was accomplished by the addition of a moisture system to the discharge of the potato piler.  

The system consisted of two 1 1⁄4” nozzles attached to a 1 1⁄2”inch diameter water hose.  The resulting

system sprayed water at both sides of the feedstock discharge chute.  The water was pumped out of the

back of the on‐site, 4,000‐gallon water truck. In a real production scenario, the water truck would be

eliminated by plumbing a flexible water supply to the piler conveyor.

13 | Page

The second half of the moisture solution was to design a series of sprinklers which would be placed on

top of the eASP and run off a timer.  One irrigation “sled” was used for every 30’ of eASP length.  

Because of the time of year and the excessively hot conditions, the sprinklers were run on a cycle of an

average of six minutes per cycle, six times per day. The sprinklers were successful in keeping the top of

the eASP moist.  Because the aeration system tends to blow the water back up to the top, it was not

clear how deep the water penetrated; however, field investigations indicated the water was seeping

down more than two feet.

Rain gauges were used on the top of the eASP zones to measure the amount of water delivered, and as

the basis for adjustment.  The water delivered ranged from 1‐5” per day, depending on location and

timing of the irrigation system.  Over and under‐watering was a challenge in this project.  An average of

approximately 3” per day would likely be ideal, depending on the moisture content of the original

feedstock and ambient conditions.   

In this project, the combination of feedstock which were not uniformly wet, and occasional over‐

watering, caused the pile to weep water at the lower end.  A French drain was constructed to capture

that water and re‐introduce it to the piles.  A run off capture system should be an integral part of any

eASP composting system.   

Despite the potential that the eASPs were over‐watered, actual water use for the eASP was nearly 17%

less than a comparable windrow system per cubic yard of feedstock.  Potential reasons for this include a

lower ratio of surface area to pile volume, and the lack of turning, which tends to cause a visible spike in

evaporation.

Table 1: Comparison of water use between eASP and traditional windrow method as modified by SJVUAPCD Rule

4566.
14 | Page

At 2 cubic yards per ton, a 100,000 ton‐per‐year facility would save a minimum of 1 million gallons of

water annually using the eASP system.  Using the ARB estimate of 1.5 thousand tons of CO2 equivalents

(MTCO2e) for every acre foot of water saved in California, the potential GHG savings is slightly more

than 4.5 MTCO2e per 100,000 tons of feedstock.  These savings are probably underestimated at

compost facilities, where water tends to be delivered via 400‐500 hp, 4,000‐gallon diesel water trucks.  

The savings rise, both in terms of water and GHG, when one considers the inefficiencies inherent in the

water truck system, including water loss when filling the truck and water running off the sides of the

windrows.  The water at this composting site, and many others, is pumped from a well.  GHG

equivalents are generally higher for groundwater than the statewide average; however, this depends on

the depth and flow of the well.  If the well is powered by a diesel pump, criteria pollutants are reduced

when less water is used.

The water use reductions provided in Table 1 are provided as an Excel Spreadsheet in Appendix H.

Feedstock

Feedstock for this project consisted of municipally sourced greenwaste from the Visalia‐Tulare area.  

Effort was made to get the freshest possible greenwaste feedstock for the project.  The feedstock used
15 | Page

arrived at the facility the day before the pile‐building events.  After the materials were tipped, they were

spread out and handpicked for large trash or hazardous materials, then brought to the grinding area.  

The same protocol is used for all feedstock at this site.

During pile construction, the team from O2 Compost measured bulk density and water‐holding pore

space using bucket tests which are standard in the composting business.  Moisture percentage of the

feedstock was measured using a simple postage scale and an electric heat gun to dry the materials.  The

materials are weighed wet, and then are dried and weighed until the sample weight stabilizes.  The

process takes more than one hour to complete.  Composite grab samples were taken for each zone

constructed, and sent to a laboratory to measure carbon‐to‐nitrogen ratio on a dry and wet basis.

The overall parameters of the starting feedstock mix for the three zones are as follows.

Table 2: Parameters for the starting eASP compost feedstock.

Laboratory tests for the initial C:N measurements are available in Appendix F.

Aeration System

Each of the three ASP zones had its own blower, manifold and pipes.  The aeration piping was standard

4” drain pipes, such as can be purchased at any hardware store.  These white PVC pipes come in

standard 10’ sections and are flanged on one end so they may easily be attached.  There are two kinds

of pipes, perforated and not perforated.  Each aeration line starts and finishes with 10 feet of non‐

perforated pipe, so air does not leak out from the sides of the piles.  In between were seven sections of

perforated pipe, with the holes pointed down.   Each pipe section is tacked to the ones before and after

using one screw, to ensure they are not pulled apart during pile construction. The aeration pipes were

buried in a plenum of coarse‐ground wood chips approximately 1 foot deep.  The use of chips ensures

the air coming out of the perforated pipes is not blocked by dense material compacted by the weight of

the pile
16 | Page

The standard manifold for each ASP branches off to four 90’ long aeration pipes, each five feet apart.  

The manifold was constructed of 6” diameter PVC sewer pipe, again, standard at most large hardware

stores.  These pipes are green and are also sold in 10’ sections.  For this project, the pipes were cut with

a hand saw to construct the manifold.  Standard T and elbow connections were used to assemble the

pieces, and were tapped together using a rubber mallet. The 6” sewer pipe was stepped down to the 4”

sewer pipe using standard connectors.   The blower was connected to the manifold using a rubber

fitting, which was purchased from the blower vendor.

With every Aerated Static Pile (ASP) Compost System, a key design objective is to provide uniform

airflow across the base of the pile (side to side and end to end).  The aeration zone is located beneath

the core of the pile and consists of perforated pipe overlain by a layer of coarse woody material

(referred to as the “plenum layer”).  As the ASP System is constructed, the aeration zone is sealed on all

sides by the overlying mix of materials to prevent short‐circuiting of airflow to the atmosphere.   

When the aeration blower turns on, the plenum layer pressurizes; the air first flows laterally across the

base of the pile and then vertically up through the compost mix.  By controlling the frequency and

duration of airflow, the operator is able to maintain aerobic conditions throughout the pile and optimize

the biology of the composting process.

For this project, each zone was aerated using independent solar powered blowers. Each system included

a pair of photovoltaic panels, charge controller, inverter, batteries, and a 1.5 hp 3‐phase blower).

system is complete; panels are in place for Zone 2.

Two sets of field tests were conducted on each of the three aeration manifolds to confirm that: 1) the

airflow was balanced within the aeration system; and 2) sufficient air volume was delivered to the

compost mix.  These tests evaluated static pressure and airflow velocity. For the two tests, 3/8‐inch

diameter holes were drilled into the PVC aeration manifold at five junctions (pressure and velocity) and

at the down‐stream ends of each of the four lateral aeration pipes (pressure only).  Figure 1 provides a

schematic drawing of one aeration system to illustrate the layout of the aeration pipes and the locations

for the two sets of tests.

The pressure at nine different locations in each of the three aeration systems was determined using a

magnehelic pressure gauge. The velocity of airflow was determined using a hot‐wire anemometer.  An

example of each monitoring device is shown below.

These test results confirmed that uniform airflow and sufficient air volume was delivered to the EASP

System to meet the objectives of the project.

Photovoltaic System

Recent advances in photovoltaic (PV) technology make powering small motors at remote locations more

feasible than ever before.  The blower motors weigh about 90 pounds, and produce a maximum of 1.5

horsepower each.  The blowers run directly from the four deep‐cycle flooded lead acid batteries which

were placed inside the white cabinets.  The PV panels charge the batteries.  The white cabinets also

contain the inverter, which converts the direct current power produced by the panel into alternating

current, as well as the timers, switches and the wiring harness, which limited the electrical operations in

the field to basically a plug‐and‐play situation.

The full PV systems were specified by O2 Compost and shipped to the site by Automation Electric and

Controls of Mt. Vernon, Washington.  The arrays were assembled on site by the study team. The hard

cost for the complete units, including panels, batteries, inverter, timers, switches and blowers, as well as

all piping, was about $10,000 each.

The PV panels were mounted on specially constructed aluminum frames.  The frames were bolted to

standard 4 x 4 wooden posts with lag screws.  The posts were nailed to standard concrete/metal

footings available at any hardware store.  The panels were angled 45 degrees to the south.  Because the

summer sun in the SJV is so strong, and there was no shade at the site, it was not necessary for the

panels to track the movement of the sun, or to match the angle of the panels with the angle of the sun.  

These steps may be necessary for winter operations.

top. From left to right: Harold Ruppert and Peter Moon of 02 Compost, and Kevin Barnes, City of Bakersfield.

The blowers were cycled to operate 2 minutes out of every 20, easily achievable with summer sunlight

in California.  The only problem with the PV system concerned the small exhaust fan which was used to

cool the components inside the white metal cabinet.  August 2012 was an extremely hot month in the

southern SJV, with nominal daytime temperatures above 100 degrees F nearly every day the project was

in operation.  This caused the exhaust fan to work overtime, drawing down the batteries.  The

thermostat on the exhaust fan ultimately had to be raised to its maximum level, potentially exposing the

batteries and inverter to damaging heat buildup.  Although the system continued to function throughout

the life of the project, the batteries were degraded.  For a permanent system, care should be given to

place sensitive electronics in the shade.

Temperatures and pathogen reduction

Section 17868.3 of Title 14 of the California Code of Regulations sets minimum temperature standards

for pathogens reductions during composting.  These standards, known as PFRP, are as follows:

 If the operation or facility uses a windrow composting process, active compost shall be maintained under

aerobic conditions at a temperature of 55 degrees Celsius (131 degrees Fahrenheit) or higher for a

pathogen reduction period of 15 days or longer. During the period when the compost is maintained at 55

degrees Celsius or higher, there shall be a minimum of five (5) turnings of the windrow.

 If the operation or facility uses an aerated static pile composting process, all active compost shall be

covered with 6 to 12 inches of insulating material, and the active compost shall be maintained at a
21 | Page

temperature of 55 degrees Celsius (131 degrees Fahrenheit) or higher for a pathogen reduction period of

3 days.

These temperature standards are backed up by pathogen testing at the end of the curing stage, before

finished compost may be sold.

A five‐foot long temperature probe was purchased in order to take temperature readings.  

Temperatures for the eASP were taken at three different depths (2’, 3’ and 5’ down) and at two

locations on the pile.  For control windrows, temperatures were taken at two locations per pile.  Control

windrows were turned on the operator’s regular turning schedule, but were not turned on the basis of

the age of any individual control.

Graph 1: Comparison of temperature readings between eASP and windrow over 22‐day active composting period.

All eASP and control windrows met or exceeded state minimum temperature requirements for

pathogen reduction.  On average, eASPs ran hotter than windrows in this experiment.  This is likely due

to the larger pile size and the thick blanket of finished compost, both of which tend to hold in heat. Full

temperature data is available in Appendix G.

Curing and testing

All eASP zones and windrows were allowed to compost for 30 days.  At 30 days, composite samples

were taken of each eASP zone and control windrow using the process described in California regulations

(14 CCR, Section 17868.1) and were sent to Soil Control Laboratories in Watsonville, CA.  Soil Control
22 | Page

Labs is one of two laboratories in California approved by the U.S. Compost Council’s Seal of Testing

Assurance (STA) program. The program was created in 2000 by the leading compost research scientists

in the United States. The science behind the development of the STA Program and the various tests that

are used is contained in ‘Test Methods for the Examination of Composting & Compost’, a publication

which includes a suite of physical, chemical and biological tests.  STA testing can be performed by a

group of independent, certified labs across the U.S. and Canada.

Results of the 30‐day STA testing are below.

Table 5: Comparison of 30‐day laboratory results for all three eASP zones and control windrows.

In order to reach maturity, the compost process generally needs to run 60 days or more.  So it comes as

no surprise that all 30‐day‐old samples show an immature product.  In nearly all maturity

measurements, however, the eASP appears to be slightly more mature or more stable than its windrow

counterpart, despite the lack of turning.  In terms of CO2 evolution‐‐the stability measurement‐‐the

eASP is superior in all 3 pairings.  Therefore, we may conclude that the eASP will have a beneficial

impact for operators on compost production issues; that is; we see no evidence of a time penalty for

switching to the no‐turn active compost method.

We should note that starting C:N ratios were below what is considered optimum.  Composting experts

agree an ideal C:N ratio for initial feedstock is between 25 and 35 parts carbon to one part nitrogen.   

This is particularly important for small manure facilities.  Practically speaking, it is very difficult for large‐

scale operators to change the C:N ratio of large volumes of material.   Sampling bias in C:N
23 | Page

measurements is inherent because large particles are filtered out before final testing, and larger

particles tend to be high in carbon, so actual stating C:N is likely higher than reported.

After 30 days, the control windrows moved into the regular composting operation on site.  They were

not sampled again.  The three eASP zones were treated differently, as follows:

 Zone 1: Scooped up and placed into a windrow, treated the same as other curing piles on the

site

 Zone 2: Flipped over onto Zone 1 and aerated for an additional 30 days

 Zone 3: Left in place and aerated for an additional 30 days

After 60 days, the three zones were again sampled, and the composite sample was sent to Soil Control

Labs for a second round of STA testing.

Results of the 60‐day STA testing are below.

Table 6: 60‐day laboratory results for three eASP zones.
24 | Page

The complete tests for 30 and 60 days are found in Appendix D.  Zone 1 failed the pathogen test at 60

days, even though it passed a similar test at 30 days.  Per state law, this material could not be sold until

it was re‐composted and passed a subsequent test.  Contamination of previously pathogen reduced

materials is not uncommon at large composting sites.  It can come from many sources, including

handling by equipment that comes into contact non‐pathogen‐reduced materials, as well as external

sources such as birds.  The failure to achieve criteria is not believed to be related to the eASP

composting technology employed, as this pile did pass its pathogen test at 30 days.

The complete 30‐day laboratory tests are available in Appendix D.  The 60‐day tests are available in

Appendix E.

Diesel Emissions Reductions

Reducing diesel emissions are important for mitigating the air quality impacts of composting.  The VOCs

emitted from the degradation of organic materials are much more voluminous than equipment

emissions, but are biogenic in nature and comprised primarily of light alcohols (Kumar et al 2009).  Light

alcohols are not strongly implicated in ozone or secondary aerosol formation. (Carter et al 1995).  NOx

from diesel engines is implicated in both.  Any process changes which reduce overall diesel use on the

compost site are real, permanent reductions which will lead to reduced criteria pollutant levels in the

SJV.

The project resulted in an average reduction in diesel use per ton of feedstock of approximately 87%,

with commensurate reductions in all criteria pollutants and greenhouse gases associated with diesel

use.  When compared against older equipment, this could result in a reduction of as much as 7.5 tons of

NOx and 2.5 tons of non‐methane hydrocarbons per year per 100,000 tons processed.  Savings against

newer equipment generally run less than one ton of pollutant per 100,000 tons.  Based on the

estimates, and assuming two cubic yards per ton, diesel savings are calculated to be 2,940 gallons per

year for the theoretical 100,000‐ton‐per‐year facility. Lower density materials actually increase the

diesel savings.

Cleaner diesel engines, electrification of grinders and other diesel equipment on compost sites, and the

potential future advent of hybrid diesel‐electric or natural‐gas‐powered heavy duty equipment will all

contribute to a gradual shift toward less diesel use.  However, bringing three‐phase power to remote

composting sites can be very expensive; costs exceeded $1 million for the Mt. Vernon composting site in

Bakersfield.  Newer loaders and trucks will be phased in under mobile source programs run by the SJV

and the ARB, and are also expensive propositions for compost operators.  Natural gas and hybrid loaders

are still not commercially available, and will likely remain cost prohibitive for some time.

This project measures the reductions in diesel use from conveying materials directly from a grinder

output to a pile.  In a typical composting site, these tasks would be performed by diesel loaders, typically

working in concert with diesel powered end‐dump or side‐dump trucks.  For the purposes of this

exercise, we measured only a short run covered by one telescopic‐transfer conveyor that was available

to rent for the project.  However, a full scale production would realize much greater diesel reductions.  
25 | Page

Facility‐wide reductions could be estimated on a facility‐by‐facility basis, using a point half the distance

from the site’s grinder to the property line, as an average distance materials would need to be moved,

and then calculate the amount of diesel hours needed to perform that operation.

We also measured the amount of time necessary to operate a water truck in order to maintain moisture

in composting windrows.  With the eASP, these functions were provided during pile build, and

thereafter by a sprinkler system.  One of the main drawbacks of using sprinklers on windrows is the

potential for them to become ensnared in windrow turning equipment, resulting in their destruction

and loss of valuable turner time.  This is not a problem with the no‐turn eASP system.

Even with extensive use of conveyors, loaders will remain indispensable equipment at compost site

because of their speed, maneuverability and versatility.   However, it may be possible to significantly

reduce their use, which represents a cost savings and an air pollution benefit.  Compared to grinders,

conveyors use relatively little electricity, and can easily be powered by generators if necessary.

This project used a slow‐speed shredder instead of a high speed grinder to prepare the feedstock for

composting.  The shredder uses an engine roughly half the size of a comparable grinder.  It was also a

newer model, with a Tier 4 compliant engine.  The emissions reductions gained from this type of

replacement are not considered as benefits from this project.  

Overall, the eASP resulted in an 87% reduction in diesel fuel use per ton of production, and a

corresponding reduction in the amount of criteria pollutants and GHGs from equipment use.  The

amount of actual pollutants reduced depends on the age of the diesel equipment in question.  For the

purposes of this project, pollutant reductions were calculated for both 1996 (Tier 0) engines and 2007

(Tier 3) engines.   

The full diesel use calculations, and the calculations of reduced emissions from diesel use, are available

in Appendix C.

Land Use Reductions

Taller, wider extended ASPs can process more materials per acre of land than traditional windrow.  To

the extent that many piles are laid parallel to one another, this advantage is increased.  Larger piles can

be moved or even cured using turner devices that rely on small conveyors rather than the spinning shaft

typically used for windrows.  

Land purchase is typically a concern when building a new compost site, but can also come into play if an

existing operator was forced to construct a water‐impermeable pad for active‐phase composting.  Based

on the experiment, and compared to standard windrows at the Mt. Vernon compost facility in

Bakersfield, the eASP can process approximately 3,552 tons per acre, while windrows (using some of the

largest machines available) can process 1,580 tons per acre, an advantage of some 55.5% for the eASP.

For the theoretical 100,000 ton‐per year‐facility, the amount of acreage needed for active phase

composting is also reduced by 55%.  The amount of acreage necessary vary depending upon whether a
26 | Page

composter uses a 70‐day compost period or allows materials to cure to 90 days without being moved off

the pad.  The full calculations are available in Appendix I.

Discussion

Composting is widely viewed as an inherently sustainable activity.  The process of recycling nutrients

and organic matter back into the soil will grow in importance over the coming years as the world’s

farmers struggle to feed billions of people.  Composting is a critical part of California’s efforts to

achieve75% recycling and composting, as mandated by AB 341 (Chesbro, Statutes of 2011).  In fact,

attainment of the AB 341 standard is widely viewed as impossible without a rough doubling of

composting capacity in California.  This comes at a time when compost facilities are increasingly difficult

and expensive to site, primarily due to air pollution issues.

The primary composting process used in California and much of North America, open windrows, may

not be inherently sustainable.  The process and profitability of operators heavily depends on the wide

availability of relatively inexpensive diesel fuel.  Composting facilities have little ability to raise their

tipping fees or the prices for their finished product without losing market share to low‐priced landfilling

and relatively inexpensive manufactured fertilizer.  If diesel fuel prices were to rise significantly in the

future, compost facilities would find their profit margins squeezed and some may go out of business.

Composting facilities are difficult to site because of odor issues.  Odor is most commonly associated with

receiving and mechanical turning of relatively fresh feedstock.  Rapid handling of fresh, odoriferous

feedstock can be achieved by most operators; however, it is not always possible to reduce or alter

turning schedules.  Eliminating the need to turn during the odorous active composting phase may allow

compost facilities to site closer to urban areas that generate feedstock, thus reducing diesel‐intensive

feedstock hauling.

As California increases its efforts to reduce landfilling and greenhouse gas generation, food waste

composting will increase.  Unlike green waste, food waste qualifies for GHG credits when composted.  

Food waste putrefies rapidly; however, often creating intense odors.  No odorous emissions from the

eASP built for this project were ever detected.  Composting methods which reduce handling activities

during the active phase seem likely to reduce odor issues, again, potentially allowing siting of

composting facilities closer to the places where both food and green wastes are generated.
27 | Page

Previous emissions studies where foodwaste was a significant part of the feedstock suggest that VOC

emissions could be significantly higher compared to green‐waste ‐only piles, but this question has not

been adequately researched.  The South Coast AQMD already requires large foodwaste composting

operators to install VOC capture systems.  The high cost of these systems has limited food waste

composting opportunities within the four counties of the SCQAMD.

Emissions reductions for VOCs (primarily non‐methane, non‐ethane organic compounds, or NMNEOC)

from the eASP were expected in this study, but the measured reductions exceeded all expectations.  In

searching for potential explanations for the high rate of control, several factors come to the fore.

 EASPs reduce surface area.  In a 2009 study for the San Joaquin Valley Unified Air Pollution

Control District, very small windrows with high surface areas were shown to have higher

emissions rates than the ordinary sized control windrow.

 The eASP surface was kept wet.  In the same previous study for the San Joaquin Valley Unified

Air Pollution Control District, wetting the surface of the windrow prior to turning reduced overall

emissions by 19%.  This study supports that finding and suggests that a consistently wet surface

may produce even higher emissions control.  With a smaller surface area, the eASP is less prone

to drying out during hot SJV summers.

 The biofilter layer was 12” or more thick.  In two previous studies, one by the California

Integrated Waste Management Board and the aforementioned 2009 air district study, 6” thick

compost caps delivered emissions reductions of 75% and 53%, respectively.  Commercial

biofilters are commonly 3’ thick or greater, depending on the application.  This study suggests

that thicker biofilter compost cap layers are more capable of degrading NMNEOCs and other

undesirable compounds.

 More uniform air and water.  Aeration is applied uniformly to the greenwaste,

maximizing aerobic decomposition and reducing anaerobic pockets.  The other primary

ingredient, water, is also applied regularly so that overly dry conditions never suppress microbial

activity, further enhancing rapid and efficient aerobic decomposition.  Controlling the aerobic

activity is a key ingredient in maintaining more efficient and favorable aerobic decomposition

regarding both the type of compounds generated and the amount of compound air emissions

released per ton of greenwaste.   

The main component of the compost cap, unscreened finished compost, is available at all composting

sites.  Methods to apply the cap on conventional windrows tend to be diesel intensive; however,

conveyorization can be used to apply the layer on static piles with set site configurations.   SJVUAPCD

Rule 4566 requires the biofilter compost cap to be replenished after windrow turning at the very largest

facilities, increasing their diesel footprint.  State regulations require windrows to be turned five times in

15 days for pathogen reduction.  However, state regulation does not require static piles with a one‐foot‐

thick insulation layer to be turned for pathogen reduction purposes. By using the eASP system,

operators can apply just one cap for the entire active composting phase.  

The solar powered eASP system reduces dependency on diesel, and reduces feedstock handling during

the critical active composting period, when odor and emissions potential is at its highest.  The use of
28 | Page

solar power means aeration systems can be located where they are needed, in remote locations,

without expensive grid connections.  In the SJV, available sunshine year‐round is more than adequate

for the relatively small motors needed for aeration, and with adequate battery backup such systems

should be operable even during the rare prolonged foggy or rainy winter periods.

A drawback for the prototype eASP system was the, above‐ground aeration pipes, which were destroyed

during pile deconstruction.  This problem can be overcome by substituting thick, durable pipes made of

heavy plastic (typically used for water mains) in place of the thinner, low‐cost pipes used in this project.  

Also, low‐cost methods to embed aeration pipes in the ground should be technologically feasible for

most operators, and are available commercially from some vendors.

Another challenge was setting proper moisture levels.  Though the temporary eASP sprinkler system

rigged for this project worked remarkably well, it was not as precise or as consistent as desirable.  Once

a compost operator configures an eASP site, designing a more effective, permanent system providing

near‐ideal moisture management should not prove a significant challenge.  A similar situation occurred

for the initial watering of the feedstock; the temporary system designed for this project proved

adequate.  However, permanent, engineered systems—perhaps integrated with the conveyor—would

certainly provide more uniform feedstock moisture and would quite possibly save additional water.

A final drawback for larger pile sizes is the difficulty of monitoring conditions deep within the pile.  The

five‐foot‐long temperature probe purchased for this project is the longest readily available.  However, it

is not always possible or advisable to force the probe the full 5’ into a pile.  Also, this probe did not

measure relative moisture.  Technology is rapidly solving these problems.  Low‐cost remote data loggers

are now available.  These can be buried within piles, and can record a variety of parameters, including

temperature and moisture, over the life of the project.  Future projects should include the use of these

devices.

Conclusions

This project compared standard windrow composting to an eASP design to compare emissions.  The

result of this project does establish that the eASP design tested reduces both water use and air

emissions.   The eASP was tested in a single selected configuration; therefore, the results of this project

do not establish optimal blower speeds or water application rates.  Additional testing would be required

to establish a user guide to ensure minimum operating costs, best quality of product and minimum

water use and air emissions.

The solar powered eASP with a biofilter compost cap appears to be a viable method for commercial‐

scale composting.  The demonstrated NMNEOC, ammonia and GHG emissions reductions achieved in

this project from the piles of decomposing organic materials were significant, in the range of 98%, 95%

and 70% respectively.  These levels of control match or exceed commercially available systems costing

many times more.  The practical effect of using electric conveyors instead of diesel‐powered trucks and

loaders to build the pile, and of using solar‐powered aeration instead of diesel‐powered windrow

turners, creates additional emissions reductions of NOx and other criteria pollutants which are
29 | Page

important in non‐attainment air basins such as the San Joaquin Valley.  The emission reductions cited

are the result of a closely managed demonstration project and should not be considered as the expected

performance of and “achieved in practice” permanent facility. Achieved in practice results might be less

than the closely managed demonstration project; however additional reductions might be achieved by

further work to establish optimal operating conditions.

In addition to the diesel reductions and the greatly reduced emissions from decomposing organic

wastes, conversion to eASP systems has the potential to save operators money and reduce GHG impacts

through process water savings and shrinking the amount of land needed to conduct active‐phase

composting.

In terms of product quality and maturity, the eASP appears to be at least as good as windrow systems.

1. Summary

A prototype Aerated Static Pile (ASP) composting process was assembled and operated to test both 

ability to produce quality compost and to quantify air emissions. The ASP utilized ambient air blown 

into the pile from the bottom; the blowers were powered by photovoltaic panels and associated 

batteries. The ASP had a biofiltration layer added to the surface to reduce air emissions. A series of 

compost windrows were built concurrent with the ASP using the same materials. The air emissions from 

the ASP were compared to the on-site measured air emissions of the current industry-standard windrow 

composting method. 

Emissions were measured using the standard methods and techniques used for San Joaquin Valley Air 

Pollution Control District (SJVAPCD) regulatory compliance. This includes the use of the USEPA flux 

chamber as modified under South Coast Air Quality Management District (SCAQMD) Rule 1133, and 

analysis using SCAQMD Method 25.3 for VOC and 207.1 for ammonia (NH3). In addition to these 

traditional methods, nitrous oxide (N2O) was measured using NIOSH 6600 and organic species were 

measured using USEPA TO-15.

Tables 1.1 and 1.2 provide the measured and extrapolated emissions for the ASP and window 

(respectively) for the cycle periods of 22 days (all measurements) as well as 30 days and 60 days (both 

measured and extrapolated). The units are pounds of emitted compound per ton of initial compost mix.

The VOC reduction achieved was greater than 97% when compared to any benchmark, and equal to or 

better than all known commercial VOC reduction technologies regardless of price. The windrow (onsite control) emissions were higher than expected, but even using the SJVAPCD emission factor, the 

control was still and impressive 98%.

Ammonia emission reductions were also substantial. However these varied based on the compared 

cycle time. For the complete cycle the ASP ammonia emissions, based on laboratory measurement, 

showed a 92% reduction over the on-site windrow. Greenhouse gas emissions were also reduced, but 

not as significantly as VOC and ammonia

2. Project Overview

This project was funded by a grant from the San Joaquin Valley Air Pollution Control District (SJVAPCD) 

to demonstrate the feasibility of a commercial-scale positively aerated, ASP compost system. The 

project was co-managed by the Association of Compost Producers and CalRecycle, with help from the 

City of Bakersfield and O2 Compost. 

There were several facets to this project, including diesel fuel reduction and renewable energy, which 

were met by the use of electric conveyors to form the pile and photovoltaic power to run the blowers 

aerating the ASP. Our team was retained to sample and calculate the air emissions from the ASP 

compost system, and compare those emissions with those emitted by industry-standard composting 

windrows which were built out of the same materials on the same day. 

The ASP was covered by a biofiltration layer of finished compost to control air emissions. The ASP was 

operated in a positive ventilation mode, meaning that the air to supply cooling, moisture control, and 

metabolic oxygen was blown into the pile with exhaust leaving the pile surface. Emissions sampling 

occurred during one hour cycles. Blowers generally ran two minutes out of every 20, meaning that one 

emissions sampling event would capture three full blower cycles.

3. Process Description

Prototype ASP

Figure 3.1 shows a plan and section of the 

prototype ASPs. There were three separate zones 

constructed to represent three different ages of 

compost. The starting feedstock was placed on top 

of previously installed air distribution piping and a 

plenum of large nominal diameter wood chips 

roughly one foot deep. After the compost was 

placed to approximately 8 feet of average depth, a 

nominal 12 inches of finished, unscreened compost 

was placed on the top of the pile as a biofilter 

compost cap. The cap acts much like a biofilter, 

reducing pollutants as they migrate up to the 

surface of the pile.

Figure 3.1 Plan and Section of ASP Piles.

The compost pile with biofilter was used to calculate total surface area. The mass of biofilter material 

was not used in the compost mix mass calculation.

The total surface area of the ASP was 785 m2and the total mass of compost mix in the cells was 695 

tons. The mass value of the compost cells was supplied by O2Compost. For emissions calculation 

purposes the ASP pile was assumed to be operational for a 21 day compost cycle.

Windrow

The host site normally composts in windrows. 

Windrows are the standard technology currently 

used in the United States to compost 

greenwaste. Figure 3.2 shows the layout of the 

windrows being tested for this study. The 

windrows shrink significantly during the compost 

duration. The initial area of a windrow was 

calculated to be 1,311 m2. At the end of cycle, 

this shrinks to 919 m2. For emissions calculation 

purposes it was assumed the shrinkage occurred 

linearly over the compost cycle. The site 

operator, Harvest Power, provided the mass of 

typical windrow as 782 tons of compost. Photo 

3.2 shows a typical windrow on the site. The 

normal operating cycle for windrows at this site 

is 65 days or longer. The windrows are turned using a specialized mechanical device approximately 

eight times during the process cycle.

4. Emissions Measurement

All emissions measurements were made using USEPA validated flux chamber technology modified per 

SCAQMD Rule 1133 for measurement of composting air emissions. Photo 4.1 shows a typical 

measurement. The testing was conducted at pre-determined locations per zone (up to four 

measurements per zone and test condition) as a function of process day in the life cycle of the

composting technology.

Emissions were sampled and analyzed per SCAQMD 

Method 25.3 for VOC (total non-methane, non-ethane 

hydrocarbon), carbon dioxide (CO2), and methane

(CH4). Ammonia (NH3) was sampled and analyzed

using SCAQMD Method 207.1. Nitrous oxide (N2O) 

was sampled and analyzed using NIOSH Method 6600 

(FTIR). Speciated organics were sampled and analyzed

using USEPA Method TO-15. 

Every test location completed measurements for 

Method 25.3. Only 25% of the test locations had the 

analysis completed for Method 207.1 (NH3), NIOSH 

6600 (N2O), and TO-15. 

For the ASPs, samples were taken on process days 3, 4, 

5, 6, 10, 12, 13, 15, 17, 18, and 23. For the windrows, 

samples were taken on process days 0 (feed stock), 2, 3, 9, 11, 15, 29, and 63.

In general samples were taken in clusters of four representing near-field spatial variability for the ASPs 

and top/sides for the windrows. Far-field spatial measurements, that is measurements on the opposite 

end of the pile/windrow were taken on process day 4 for the ASPs and process day 15 for the windrows. 

These measurements were taken to determine if there were differences in emissions in different parts 

of the pile. In addition, a mixing event for the windrows was measured on process day 11.

A summary of the data is provided (in flux units) for the ASP (Table 4.1) and windrows/feedstock (Table 

4.2). Complete data is provided in the Appendix. The accompanying Data Validation Technical 

Memorandum contains the complete data set, including QA/QC.

For emissions reporting purposes, only the laboratory ammonia data was used.

5. Emissions Calculations

In order to calculate emissions for the complete process cycle, a process cycle was simulated using the 

data collected on the specific process days. The process cycle days that were not tested had the 

emissions estimated based on linear interpolation of the test data.

ASP Emissions

The simulated emissions in pounds per ton per day for each cycle day are provided in Attachment 1. 

The program design for the ASP anticipated that the primary composting process would take 22 days. 

However emissions estimates were extrapolated to both a 30 day period and a 60 day period. Table 5.1 

presents the results of the 22 day measured period as well as the extrapolated longer periods.

Table 5.1 ASP Air Emissions (pounds per ton compost mix) for a 22 day compost period with 

extrapolated estimates for 30 day and 60 day periods.

Windrow Emissions

The windrow emissions were calculated in the same manner as the ASP emissions. The only exception is 

that windrow emissions included mixing events. The measured mixing event data showed that mixing 

increased the daily emissions by 8% on the mix day. Therefore, for the simulated emissions profile, each 

mix day emissions were multiplied by a factor of 1.08. 

Windrow emissions estimates were calculated for a 22 day period, a 30 day period and a 60 day period. 

Table 5.2 presents the results of the windrow emissions calculations

Greenhouse Gas Emissions

Using the CARB (40 CFR Part 98) CO2 equivalency factors for the 100 yr planning horizon of

Methane 21

Nitrous Oxide 310

the CO2 equivalency of the all the greenhouse gases were calculated as are shown as a comparison of 

windrow to ASP in Figure 6.6. The ASP is shown to be significantly lower than windrow composting 

using this metric.

Emissions Reductions by ASP Technology

Figure 6.7 shows the emissions reductions for the ASP technology as compared to the control windrow 

technology. The calculation was made for the 22 day design period as well as extrapolated to 30 day 

and 60 day periods. Table 6.1 provides the quantitative data used to generate Figure 6.7.

Figure 6.7 Emissions Reduction Summary (as compared to tested control windrow).

Table 6.1 Emissions Reduction Summary (as compared to tested control windrow).

VOC emission reduction from ASP composting was nearly 99% based on the control windrows for all the 

cycle periods evaluated. The cycle period did affect both ammonia emissions reduction and methane 

emissions significantly. This is because the windrow ammonia emissions occurred late in the cycle and 

the ASP methane emissions occurred early in the cycle.

Table 6.2 presents the emissions reductions as compared to current regulatory emission factors from 

SJVAPCD and SCAQMD. VOC and ammonia emission reductions were ranged from 97% to 99%. The 

methane emissions from the ASP prototype were significantly higher than the current SCAQMD 

emission factor.

Discussion

The combination of better process control and the surface biofilter layer produced far lower emissions 

from the ASP as compared to the current industry-standard windrow. The degree of control for both 

VOCs and windrows exceeded that expected with even synthetic cover technologies. The relatively high 

level of control of greenhouse gas emissions was a surprise. It is important to note that this is the first 

thorough test of this technology, and further testing and evaluation should be completed before these 

high levels of control can be assured on an industry-wide basis.

INTERPRETATION:

Is Your Compost Stable? Page two of three

Respiration Rate

7.9 Moderate-selected use mg CO2-C/g OM/day

The respiration rate is a measurement of the biodegradation rate of the organic matter in the sample (as received).

The respiration rate is determined by measuring the rate at which CO2 is released under optimized moisture and

temperature conditions. 

Biologically Available Carbon

10 Moderate-selected use mg CO2-C/g OM/day

Biologically Available Carbon (BAC) is a measurement of the rate at which CO2 is released under optimized moisture, temperature, 

porosity, nutrients, pH and microbial conditions. If both the RR and the BAC test values are close to the same value, the pile is 

optimized for composting. If both values are high the compost pile just needs more time. If both values are low the compost has 

stabilized and should be moved to curing. BAC test values that are higher than RR indicate that the compost pile has stalled. This 

could be due to anaerobic conditions, lack of available nitrogen due to excessive air converting ammonia to the unavailable nitrate

form, lack of nitrogen or other nutrients due to poor choice of feedstock, pH value out of range, or microbes rendered non-active.

Is Your Compost Mature?

AmmoniaN:NitrateN ratio

39 immature

Composting to stabilize carbon can occur at such a rapid rate that sometimes phytotoxins remain in 

the compost and must be neutralized before using in high concentrations or in high-end uses. This 

Ammonia N ppm step is called curing. Typically ammonia is in excess with the break-down of organic materials resulting

1300 immature in an increase in pH. This combination results in a loss of volatile ammonia (it smells). Once this toxic 

Nitrate N ppm ammonia has been reduced and the pH drops, the microbes convert the ammonia to nitrates. A low 

33 immature ammonia + high nitrate score is indicative of a mature compost, however there are many exceptions. 

pH value For example, a compost with a low pH (<7) will retain ammonia, while a compost with high lime content 

5.37 immature can lose ammonia before the organic fraction becomes stable. Composts must first be stable before 

curing indicators apply.

Cucumber Bioassay

100.0 Percent Cucumbers are chosen for this test because they are salt tolerant and very sensitive to ammonia

and organic acid toxicity. Therefore, we can germinate seeds in high concentrations of compost to 

measure phytotoxic effects without soluble salts being the limiting factor. Values above 80% for both percent emergence and 

vigor are indicative of a well-cured compost. Exceptions include very high salts that affect the cucumbers, excessive concentrations 

of nitrates and other nutrients that will be in range when formulated to make a growing media. In addition to testing a 1:1 compost:

vermiculite blend, we also test a diluted 1:3 blend to indicate a more sensitive toxicity level. 

Is Your Compost Safe Regarding Health?

Fecal Coliform

< 1000 / g dry wt. Fecal coliforms can survive in both aerobic and anaerobic conditions and is common in all initial 

compost piles. Most human pathogens occur from fecal matter and all fecal matter is loaded in fecal coliforms. Therefore fecal

coliforms are used as an indicator to determine if the chosen method for pathogen reduction (heat for compost) has met the

requirements of sufficient temperature, time and mixing. If the fecal coliforms are reduced to below 1000 per gram dry wt. it is

assumed all others pathogens are eliminated. Potential problems are that fecal coliform can regrow during the curing phase or

during shipping. This is because the conditions are now more favorable for growth than during the composting process.

Salmonella Bacteria

Less than 3 3 / 4g dry wt. Salmonella is not only another indicator organism but also a toxic microbe. It has been used in the 

case of biosolids industry to determine adequate pathogen reduction. 

Metals

Pass The ten heavy metals listed in the EPA 503 regulations are chosen to determine if compost 

can be applied to ag land and handled without toxic effects. Most high concentrations of heavy metals are derived from

woodwaste feedstock such as chrome-arsenic treated or lead painted demolition wood. Biosolids are rarely a problem. 

Does Your Compost Provide Nutrients or Organic Matter?

Nutrients (N+P2O5+K2O)

3.1 Average nutrient content

This value is the sum of the primary nutrients Nitrogen, Phosphorus and Potassium. Reported units are consistent with those 

found on fertilizer formulations. A sum greater than 5 is indicative of a compost with high nutrient content, and best used to supply

nutrients to a receiving soil. A sum below 2 indicates low nutrient content, and is best-used to improve soil structure via the

addition of organic matter. Most compost falls between 2 and 5.

INTERPRETATION: Page three of three

AgIndex (Nutrients/Na+Cl)

10 Average nutrient ratio Composts with low AgIndex values have high concentrations of sodium and/or chloride

compared to nutrients. Repeated use of a compost with a low AgIndex (< 2) may result in sodium and/or chloride 

acting as the limiting factor compared to nutrients, governing application rates. These composts may be used on well-draining

soils and/or with salt-tolerant plants. Additional nutrients form another source may be needed if the application rate is limited by

sodium or chloride. If the AgIndex is above 10, nutrients optimal for plant growth will be available without concern of sodium and/or

chloride toxicity. Composts with an AgIndex of above 10 are good for increasing nutrient levels for all soils. Most composts score

between 2 and 10. Concentrations of nutrients, sodium, and chloride in the receiving soil should be considered when determining

compost application rates. The AgIndex is a product of feedstock quality. Feedstock from dairy manure, marine waste, industrial 

wastes, and halophytic plants are likely to produce a finished compost with a low AgIndex.

Plant Available Nitrogen (lbs/ton)

6 Average N Provider Plant Available Nitrogen (PAN) is calculated by estimating the release rate of Nitrogen from 

the organic fraction of the compost. This estimate is based on information gathered from the BAC test and measured ammonia and

nitrate values. Despite the PAN value of the compost, additional sources of Nitrogen may be needed during he growing season to offset the Nitrogen demand of the microbes present in the compost. With ample nutrients these microbes can further breakdown organic 

matter in the compost and release bound Nitrogen. Nitrogen demand based on a high C/N ratio is not considered in the PAN calculation

because additional Nitrogen should always be supplemented to the receiving soil when composts with a high C/N ratio are applied.

C/N Ratio

18 Indicates immaturity As a guiding principal, a C/N ratio below 14 indicates maturity and above 14 indicates 

immaturity, however, there are many exceptions. Large woodchips (>6.3mm), bark, and redwood are slow to breakdown and 

therefore can result in a relatively stable product while the C/N ratio value is high. Additionally, some composts with chicken manure 

and/or green grass feedstocks can start with a C/N ratio below 15 and are very unstable. A C/N ratio below 10 supplies Nitrogen,

while a ratio above 20 can deplete Nitrogen from the soil. The rate at which Nitrogen will be released or used by the microbes is 

indicated by the respiration rate (BAC). If the respiration rate is too high the transfer of Nitrogen will not be controlable.

Soluble Nutrients & Salts (EC5 w/w dw - mmhos/cm)

9.9 High salts This value refers to all soluble ions including nutrients, sodium, chloride and some 

soluble organic compounds. The concentration of salts will change due to the release of salts from the organic matter as it degrades,

volatilization of ammonia, decomposition of soluble organics, and conversion of molecular structure. High salts + high AgIndex is 

indicative of a compost high in readily available nutrients. The application rate of these composts should be limited by the optimum 

nutrient value based on soil analysis of the receiving soil. High Salts + low AgIndex is indicative of a compost low in nutrients with 

high concentrations of sodium and/or chloride. Limit the application rate according to the toxicity level of thesodium and/or chloride.

Low salts indicates that the compost can be applied without risking salt toxicity, is likely a good source of organic matter, and that 

nutrients will release slowly over time.

Lime Content (lbs. per ton)

0 Low lime content Compost high in lime or carbonates are often those produced from chicken manure (layers)

ash materials, and lime products. These are excellent products to use on a receiving soil where lime has been recommended by 

soil analysis to raise the pH. Composts with a high lime content should be closely considered for pH requirements when formulating 

potting mixes.

Physical Properties

Percent Ash

57.0 Average ash content Ash is the non-organic fraction of a compost. Most composts contain approximately 50%

ash (dry weight basis). Compost can be high in ash content for many reasons including: excess minerilzation(old compost), 

contamination with soil base material during turning, poor quality feedstock, and soil or mineral products added. Finding the source

and reducing high ash content is often the fastest means to increasing nutrient quality of a compost.

Particle Size % > 6.3 MM (0.25")

2.7 May restrict use Large particles may restrict use for potting soils, golf course topdressings, seed-starter 

mixes, and where a fine size distribution is required. Composts with large particles can still be used as excellent additions to field 

soils, shrub mixes and mulches. 

Particle Size Distribution

Each size fraction is measured by weight, volume and bulk density. These results are particularly relevent with decisions to screen 

or not, and if screening, which size screen to use. The bulk density indicates if the fraction screened is made of light weight organic 

material or heavy mineral material. Removing large mineral material can greatly improve compost quality by increasing nutrient and 

organic concentrations.

INTERPRETATION:

Is Your Compost Stable? Page two of three

Respiration Rate

9.1 Moderate-selected use mg CO2-C/g OM/day

The respiration rate is a measurement of the biodegradation rate of the organic matter in the sample (as received).

The respiration rate is determined by measuring the rate at which CO2 is released under optimized moisture and

temperature conditions. 

Biologically Available Carbon

12 Moderate-selected use mg CO2-C/g OM/day

Biologically Available Carbon (BAC) is a measurement of the rate at which CO2 is released under optimized moisture, temperature, 

porosity, nutrients, pH and microbial conditions. If both the RR and the BAC test values are close to the same value, the pile is 

optimized for composting. If both values are high the compost pile just needs more time. If both values are low the compost has 

stabilized and should be moved to curing. BAC test values that are higher than RR indicate that the compost pile has stalled. This 

could be due to anaerobic conditions, lack of available nitrogen due to excessive air converting ammonia to the unavailable nitrate

form, lack of nitrogen or other nutrients due to poor choice of feedstock, pH value out of range, or microbes rendered non-active.

Is Your Compost Mature?

AmmoniaN:NitrateN ratio

110 immature

Composting to stabilize carbon can occur at such a rapid rate that sometimes phytotoxins remain in 

the compost and must be neutralized before using in high concentrations or in high-end uses. This 

Ammonia N ppm step is called curing. Typically ammonia is in excess with the break-down of organic materials resulting

1800 immature in an increase in pH. This combination results in a loss of volatile ammonia (it smells). Once this toxic 

Nitrate N ppm ammonia has been reduced and the pH drops, the microbes convert the ammonia to nitrates. A low 

16 immature ammonia + high nitrate score is indicative of a mature compost, however there are many exceptions. 

pH value For example, a compost with a low pH (<7) will retain ammonia, while a compost with high lime content 

5.72 immature can lose ammonia before the organic fraction becomes stable. Composts must first be stable before 

curing indicators apply.

Cucumber Bioassay

100.0 Percent Cucumbers are chosen for this test because they are salt tolerant and very sensitive to ammonia

and organic acid toxicity. Therefore, we can germinate seeds in high concentrations of compost to 

measure phytotoxic effects without soluble salts being the limiting factor. Values above 80% for both percent emergence and 

vigor are indicative of a well-cured compost. Exceptions include very high salts that affect the cucumbers, excessive concentrations 

of nitrates and other nutrients that will be in range when formulated to make a growing media. In addition to testing a 1:1 compost:

vermiculite blend, we also test a diluted 1:3 blend to indicate a more sensitive toxicity level. 

Is Your Compost Safe Regarding Health?

Fecal Coliform

< 1000 / g dry wt. Fecal coliforms can survive in both aerobic and anaerobic conditions and is common in all initial 

compost piles. Most human pathogens occur from fecal matter and all fecal matter is loaded in fecal coliforms. Therefore fecal

coliforms are used as an indicator to determine if the chosen method for pathogen reduction (heat for compost) has met the

requirements of sufficient temperature, time and mixing. If the fecal coliforms are reduced to below 1000 per gram dry wt. it is

assumed all others pathogens are eliminated. Potential problems are that fecal coliform can regrow during the curing phase or

during shipping. This is because the conditions are now more favorable for growth than during the composting process.

Salmonella Bacteria

Less than 3 3 / 4g dry wt. Salmonella is not only another indicator organism but also a toxic microbe. It has been used in the 

case of biosolids industry to determine adequate pathogen reduction. 

Metals

Pass The ten heavy metals listed in the EPA 503 regulations are chosen to determine if compost 

can be applied to ag land and handled without toxic effects. Most high concentrations of heavy metals are derived from

woodwaste feedstock such as chrome-arsenic treated or lead painted demolition wood. Biosolids are rarely a problem. 

Does Your Compost Provide Nutrients or Organic Matter?

Nutrients (N+P2O5+K2O)

3.2 Average nutrient content

This value is the sum of the primary nutrients Nitrogen, Phosphorus and Potassium. Reported units are consistent with those 

found on fertilizer formulations. A sum greater than 5 is indicative of a compost with high nutrient content, and best used to supply

nutrients to a receiving soil. A sum below 2 indicates low nutrient content, and is best-used to improve soil structure via the

addition of organic matter. Most compost falls between 2 and 5.

INTERPRETATION: Page three of three

AgIndex (Nutrients/Na+Cl)

8 Average nutrient ratio Composts with low AgIndex values have high concentrations of sodium and/or chloride

compared to nutrients. Repeated use of a compost with a low AgIndex (< 2) may result in sodium and/or chloride 

acting as the limiting factor compared to nutrients, governing application rates. These composts may be used on well-draining

soils and/or with salt-tolerant plants. Additional nutrients form another source may be needed if the application rate is limited by

sodium or chloride. If the AgIndex is above 10, nutrients optimal for plant growth will be available without concern of sodium and/or

chloride toxicity. Composts with an AgIndex of above 10 are good for increasing nutrient levels for all soils. Most composts score

between 2 and 10. Concentrations of nutrients, sodium, and chloride in the receiving soil should be considered when determining

compost application rates. The AgIndex is a product of feedstock quality. Feedstock from dairy manure, marine waste, industrial 

wastes, and halophytic plants are likely to produce a finished compost with a low AgIndex.

Plant Available Nitrogen (lbs/ton)

8 Average N Provider Plant Available Nitrogen (PAN) is calculated by estimating the release rate of Nitrogen from 

the organic fraction of the compost. This estimate is based on information gathered from the BAC test and measured ammonia and

nitrate values. Despite the PAN value of the compost, additional sources of Nitrogen may be needed during he growing season to offset the Nitrogen demand of the microbes present in the compost. With ample nutrients these microbes can further breakdown organic 

matter in the compost and release bound Nitrogen. Nitrogen demand based on a high C/N ratio is not considered in the PAN calculation

because additional Nitrogen should always be supplemented to the receiving soil when composts with a high C/N ratio are applied.

C/N Ratio

18 Indicates immaturity As a guiding principal, a C/N ratio below 14 indicates maturity and above 14 indicates 

immaturity, however, there are many exceptions. Large woodchips (>6.3mm), bark, and redwood are slow to breakdown and 

therefore can result in a relatively stable product while the C/N ratio value is high. Additionally, some composts with chicken manure 

and/or green grass feedstocks can start with a C/N ratio below 15 and are very unstable. A C/N ratio below 10 supplies Nitrogen,

while a ratio above 20 can deplete Nitrogen from the soil. The rate at which Nitrogen will be released or used by the microbes is 

indicated by the respiration rate (BAC). If the respiration rate is too high the transfer of Nitrogen will not be controlable.

Soluble Nutrients & Salts (EC5 w/w dw - mmhos/cm)

11 High salts This value refers to all soluble ions including nutrients, sodium, chloride and some 

soluble organic compounds. The concentration of salts will change due to the release of salts from the organic matter as it degrades,

volatilization of ammonia, decomposition of soluble organics, and conversion of molecular structure. High salts + high AgIndex is 

indicative of a compost high in readily available nutrients. The application rate of these composts should be limited by the optimum 

nutrient value based on soil analysis of the receiving soil. High Salts + low AgIndex is indicative of a compost low in nutrients with 

high concentrations of sodium and/or chloride. Limit the application rate according to the toxicity level of thesodium and/or chloride.

Low salts indicates that the compost can be applied without risking salt toxicity, is likely a good source of organic matter, and that 

nutrients will release slowly over time.

Lime Content (lbs. per ton)

0 Low lime content Compost high in lime or carbonates are often those produced from chicken manure (layers)

ash materials, and lime products. These are excellent products to use on a receiving soil where lime has been recommended by 

soil analysis to raise the pH. Composts with a high lime content should be closely considered for pH requirements when formulating 

potting mixes.

Physical Properties

Percent Ash

55.1 Average ash content Ash is the non-organic fraction of a compost. Most composts contain approximately 50%

ash (dry weight basis). Compost can be high in ash content for many reasons including: excess minerilzation(old compost), 

contamination with soil base material during turning, poor quality feedstock, and soil or mineral products added. Finding the source

and reducing high ash content is often the fastest means to increasing nutrient quality of a compost.

Particle Size % > 6.3 MM (0.25")

6.1 May restrict use Large particles may restrict use for potting soils, golf course topdressings, seed-starter 

mixes, and where a fine size distribution is required. Composts with large particles can still be used as excellent additions to field 

soils, shrub mixes and mulches. 

Particle Size Distribution

Each size fraction is measured by weight, volume and bulk density. These results are particularly relevent with decisions to screen 

or not, and if screening, which size screen to use. The bulk density indicates if the fraction screened is made of light weight organic 

material or heavy mineral material. Removing large mineral material can greatly improve compost quality by increasing nutrient and 

organic concentrations.

INTERPRETATION:

Is Your Compost Stable? Page two of three

Respiration Rate

7.9 Moderate-selected use mg CO2-C/g OM/day

The respiration rate is a measurement of the biodegradation rate of the organic matter in the sample (as received).

The respiration rate is determined by measuring the rate at which CO2 is released under optimized moisture and

temperature conditions. 

Biologically Available Carbon

9.5 Moderate-selected use mg CO2-C/g OM/day

Biologically Available Carbon (BAC) is a measurement of the rate at which CO2 is released under optimized moisture, temperature, 

porosity, nutrients, pH and microbial conditions. If both the RR and the BAC test values are close to the same value, the pile is 

optimized for composting. If both values are high the compost pile just needs more time. If both values are low the compost has 

stabilized and should be moved to curing. BAC test values that are higher than RR indicate that the compost pile has stalled. This 

could be due to anaerobic conditions, lack of available nitrogen due to excessive air converting ammonia to the unavailable nitrate

form, lack of nitrogen or other nutrients due to poor choice of feedstock, pH value out of range, or microbes rendered non-active.

Is Your Compost Mature?

AmmoniaN:NitrateN ratio

32 immature

Composting to stabilize carbon can occur at such a rapid rate that sometimes phytotoxins remain in 

the compost and must be neutralized before using in high concentrations or in high-end uses. This 

Ammonia N ppm step is called curing. Typically ammonia is in excess with the break-down of organic materials resulting

1200 immature in an increase in pH. This combination results in a loss of volatile ammonia (it smells). Once this toxic 

Nitrate N ppm ammonia has been reduced and the pH drops, the microbes convert the ammonia to nitrates. A low 

38 immature ammonia + high nitrate score is indicative of a mature compost, however there are many exceptions. 

pH value For example, a compost with a low pH (<7) will retain ammonia, while a compost with high lime content 

6.20 immature can lose ammonia before the organic fraction becomes stable. Composts must first be stable before 

curing indicators apply.

Cucumber Bioassay

100.0 Percent Cucumbers are chosen for this test because they are salt tolerant and very sensitive to ammonia

and organic acid toxicity. Therefore, we can germinate seeds in high concentrations of compost to 

measure phytotoxic effects without soluble salts being the limiting factor. Values above 80% for both percent emergence and 

vigor are indicative of a well-cured compost. Exceptions include very high salts that affect the cucumbers, excessive concentrations 

of nitrates and other nutrients that will be in range when formulated to make a growing media. In addition to testing a 1:1 compost:

vermiculite blend, we also test a diluted 1:3 blend to indicate a more sensitive toxicity level. 

Is Your Compost Safe Regarding Health?

Fecal Coliform

< 1000 / g dry wt. Fecal coliforms can survive in both aerobic and anaerobic conditions and is common in all initial 

compost piles. Most human pathogens occur from fecal matter and all fecal matter is loaded in fecal coliforms. Therefore fecal

coliforms are used as an indicator to determine if the chosen method for pathogen reduction (heat for compost) has met the

requirements of sufficient temperature, time and mixing. If the fecal coliforms are reduced to below 1000 per gram dry wt. it is

assumed all others pathogens are eliminated. Potential problems are that fecal coliform can regrow during the curing phase or

during shipping. This is because the conditions are now more favorable for growth than during the composting process.

Salmonella Bacteria

Less than 3 3 / 4g dry wt. Salmonella is not only another indicator organism but also a toxic microbe. It has been used in the 

case of biosolids industry to determine adequate pathogen reduction. 

Metals

Pass The ten heavy metals listed in the EPA 503 regulations are chosen to determine if compost 

can be applied to ag land and handled without toxic effects. Most high concentrations of heavy metals are derived from

woodwaste feedstock such as chrome-arsenic treated or lead painted demolition wood. Biosolids are rarely a problem. 

Does Your Compost Provide Nutrients or Organic Matter?

Nutrients (N+P2O5+K2O)

3.7 Average nutrient content

This value is the sum of the primary nutrients Nitrogen, Phosphorus and Potassium. Reported units are consistent with those 

found on fertilizer formulations. A sum greater than 5 is indicative of a compost with high nutrient content, and best used to supply

nutrients to a receiving soil. A sum below 2 indicates low nutrient content, and is best-used to improve soil structure via the

addition of organic matter. Most compost falls between 2 and 5.

Group: Sample I.d. No. 1/2 2090381

INTERPRETATION: Page three of three

AgIndex (Nutrients/Na+Cl)

9 Average nutrient ratio Composts with low AgIndex values have high concentrations of sodium and/or chloride

compared to nutrients. Repeated use of a compost with a low AgIndex (< 2) may result in sodium and/or chloride 

acting as the limiting factor compared to nutrients, governing application rates. These composts may be used on well-draining

soils and/or with salt-tolerant plants. Additional nutrients form another source may be needed if the application rate is limited by

sodium or chloride. If the AgIndex is above 10, nutrients optimal for plant growth will be available without concern of sodium and/or

chloride toxicity. Composts with an AgIndex of above 10 are good for increasing nutrient levels for all soils. Most composts score

between 2 and 10. Concentrations of nutrients, sodium, and chloride in the receiving soil should be considered when determining

compost application rates. The AgIndex is a product of feedstock quality. Feedstock from dairy manure, marine waste, industrial 

wastes, and halophytic plants are likely to produce a finished compost with a low AgIndex.

Plant Available Nitrogen (lbs/ton)

8 Average N Provider Plant Available Nitrogen (PAN) is calculated by estimating the release rate of Nitrogen from 

the organic fraction of the compost. This estimate is based on information gathered from the BAC test and measured ammonia and

nitrate values. Despite the PAN value of the compost, additional sources of Nitrogen may be needed during he growing season to offset the Nitrogen demand of the microbes present in the compost. With ample nutrients these microbes can further breakdown organic 

matter in the compost and release bound Nitrogen. Nitrogen demand based on a high C/N ratio is not considered in the PAN calculation

because additional Nitrogen should always be supplemented to the receiving soil when composts with a high C/N ratio are applied.

C/N Ratio

17 Indicates immaturity As a guiding principal, a C/N ratio below 14 indicates maturity and above 14 indicates 

immaturity, however, there are many exceptions. Large woodchips (>6.3mm), bark, and redwood are slow to breakdown and 

therefore can result in a relatively stable product while the C/N ratio value is high. Additionally, some composts with chicken manure 

and/or green grass feedstocks can start with a C/N ratio below 15 and are very unstable. A C/N ratio below 10 supplies Nitrogen,

while a ratio above 20 can deplete Nitrogen from the soil. The rate at which Nitrogen will be released or used by the microbes is 

indicated by the respiration rate (BAC). If the respiration rate is too high the transfer of Nitrogen will not be controlable.

Soluble Nutrients & Salts (EC5 w/w dw - mmhos/cm)

7.4 Average salts This value refers to all soluble ions including nutrients, sodium, chloride and some 

soluble organic compounds. The concentration of salts will change due to the release of salts from the organic matter as it degrades,

volatilization of ammonia, decomposition of soluble organics, and conversion of molecular structure. High salts + high AgIndex is 

indicative of a compost high in readily available nutrients. The application rate of these composts should be limited by the optimum 

nutrient value based on soil analysis of the receiving soil. High Salts + low AgIndex is indicative of a compost low in nutrients with 

high concentrations of sodium and/or chloride. Limit the application rate according to the toxicity level of thesodium and/or chloride.

Low salts indicates that the compost can be applied without risking salt toxicity, is likely a good source of organic matter, and that 

nutrients will release slowly over time.

Lime Content (lbs. per ton)

0 Low lime content Compost high in lime or carbonates are often those produced from chicken manure (layers)

ash materials, and lime products. These are excellent products to use on a receiving soil where lime has been recommended by 

soil analysis to raise the pH. Composts with a high lime content should be closely considered for pH requirements when formulating 

potting mixes.

Physical Properties

Percent Ash

53.5 Average ash content Ash is the non-organic fraction of a compost. Most composts contain approximately 50%

ash (dry weight basis). Compost can be high in ash content for many reasons including: excess minerilzation(old compost), 

contamination with soil base material during turning, poor quality feedstock, and soil or mineral products added. Finding the source

and reducing high ash content is often the fastest means to increasing nutrient quality of a compost.

Particle Size % > 6.3 MM (0.25")

15.2 May restrict use Large particles may restrict use for potting soils, golf course topdressings, seed-starter 

mixes, and where a fine size distribution is required. Composts with large particles can still be used as excellent additions to field 

soils, shrub mixes and mulches. 

Particle Size Distribution

Each size fraction is measured by weight, volume and bulk density. These results are particularly relevent with decisions to screen 

or not, and if screening, which size screen to use. The bulk density indicates if the fraction screened is made of light weight organic 

material or heavy mineral material. Removing large mineral material can greatly improve compost quality by increasing nutrient and 

organic concentrations.

INTERPRETATION:

Is Your Compost Stable? Page two of three

Respiration Rate

10 Moderate-selected use mg CO2-C/g OM/day

The respiration rate is a measurement of the biodegradation rate of the organic matter in the sample (as received).

The respiration rate is determined by measuring the rate at which CO2 is released under optimized moisture and

temperature conditions. 

Biologically Available Carbon

11 Moderate-selected use mg CO2-C/g OM/day

Biologically Available Carbon (BAC) is a measurement of the rate at which CO2 is released under optimized moisture, temperature, 

porosity, nutrients, pH and microbial conditions. If both the RR and the BAC test values are close to the same value, the pile is 

optimized for composting. If both values are high the compost pile just needs more time. If both values are low the compost has 

stabilized and should be moved to curing. BAC test values that are higher than RR indicate that the compost pile has stalled. This 

could be due to anaerobic conditions, lack of available nitrogen due to excessive air converting ammonia to the unavailable nitrate

form, lack of nitrogen or other nutrients due to poor choice of feedstock, pH value out of range, or microbes rendered non-active.

Is Your Compost Mature?

AmmoniaN:NitrateN ratio

160 immature

Composting to stabilize carbon can occur at such a rapid rate that sometimes phytotoxins remain in 

the compost and must be neutralized before using in high concentrations or in high-end uses. This 

Ammonia N ppm step is called curing. Typically ammonia is in excess with the break-down of organic materials resulting

1500 immature in an increase in pH. This combination results in a loss of volatile ammonia (it smells). Once this toxic 

Nitrate N ppm ammonia has been reduced and the pH drops, the microbes convert the ammonia to nitrates. A low 

9.6 immature ammonia + high nitrate score is indicative of a mature compost, however there are many exceptions. 

pH value For example, a compost with a low pH (<7) will retain ammonia, while a compost with high lime content 

6.32 immature can lose ammonia before the organic fraction becomes stable. Composts must first be stable before 

curing indicators apply.

Cucumber Bioassay

100.0 Percent Cucumbers are chosen for this test because they are salt tolerant and very sensitive to ammonia

and organic acid toxicity. Therefore, we can germinate seeds in high concentrations of compost to 

measure phytotoxic effects without soluble salts being the limiting factor. Values above 80% for both percent emergence and 

vigor are indicative of a well-cured compost. Exceptions include very high salts that affect the cucumbers, excessive concentrations 

of nitrates and other nutrients that will be in range when formulated to make a growing media. In addition to testing a 1:1 compost:

vermiculite blend, we also test a diluted 1:3 blend to indicate a more sensitive toxicity level. 

Is Your Compost Safe Regarding Health?

Fecal Coliform

< 1000 / g dry wt. Fecal coliforms can survive in both aerobic and anaerobic conditions and is common in all initial 

compost piles. Most human pathogens occur from fecal matter and all fecal matter is loaded in fecal coliforms. Therefore fecal

coliforms are used as an indicator to determine if the chosen method for pathogen reduction (heat for compost) has met the

requirements of sufficient temperature, time and mixing. If the fecal coliforms are reduced to below 1000 per gram dry wt. it is

assumed all others pathogens are eliminated. Potential problems are that fecal coliform can regrow during the curing phase or

during shipping. This is because the conditions are now more favorable for growth than during the composting process.

Salmonella Bacteria

Less than 3 3 / 4g dry wt. Salmonella is not only another indicator organism but also a toxic microbe. It has been used in the 

case of biosolids industry to determine adequate pathogen reduction. 

Metals

Pass The ten heavy metals listed in the EPA 503 regulations are chosen to determine if compost 

can be applied to ag land and handled without toxic effects. Most high concentrations of heavy metals are derived from

woodwaste feedstock such as chrome-arsenic treated or lead painted demolition wood. Biosolids are rarely a problem. 

Does Your Compost Provide Nutrients or Organic Matter?

Nutrients (N+P2O5+K2O)

3.2 Average nutrient content

This value is the sum of the primary nutrients Nitrogen, Phosphorus and Potassium. Reported units are consistent with those 

found on fertilizer formulations. A sum greater than 5 is indicative of a compost with high nutrient content, and best used to supply

nutrients to a receiving soil. A sum below 2 indicates low nutrient content, and is best-used to improve soil structure via the

addition of organic matter. Most compost falls between 2 and 5.

Group: Sample I.d. No. 2/2 2090381

INTERPRETATION: Page three of three

AgIndex (Nutrients/Na+Cl)

8 Average nutrient ratio Composts with low AgIndex values have high concentrations of sodium and/or chloride

compared to nutrients. Repeated use of a compost with a low AgIndex (< 2) may result in sodium and/or chloride 

acting as the limiting factor compared to nutrients, governing application rates. These composts may be used on well-draining

soils and/or with salt-tolerant plants. Additional nutrients form another source may be needed if the application rate is limited by

sodium or chloride. If the AgIndex is above 10, nutrients optimal for plant growth will be available without concern of sodium and/or

chloride toxicity. Composts with an AgIndex of above 10 are good for increasing nutrient levels for all soils. Most composts score

between 2 and 10. Concentrations of nutrients, sodium, and chloride in the receiving soil should be considered when determining

compost application rates. The AgIndex is a product of feedstock quality. Feedstock from dairy manure, marine waste, industrial 

wastes, and halophytic plants are likely to produce a finished compost with a low AgIndex.

Plant Available Nitrogen (lbs/ton)

8 Average N Provider Plant Available Nitrogen (PAN) is calculated by estimating the release rate of Nitrogen from 

the organic fraction of the compost. This estimate is based on information gathered from the BAC test and measured ammonia and

nitrate values. Despite the PAN value of the compost, additional sources of Nitrogen may be needed during he growing season to offset the Nitrogen demand of the microbes present in the compost. With ample nutrients these microbes can further breakdown organic 

matter in the compost and release bound Nitrogen. Nitrogen demand based on a high C/N ratio is not considered in the PAN calculation

because additional Nitrogen should always be supplemented to the receiving soil when composts with a high C/N ratio are applied.

C/N Ratio

19 Indicates immaturity As a guiding principal, a C/N ratio below 14 indicates maturity and above 14 indicates 

immaturity, however, there are many exceptions. Large woodchips (>6.3mm), bark, and redwood are slow to breakdown and 

therefore can result in a relatively stable product while the C/N ratio value is high. Additionally, some composts with chicken manure 

and/or green grass feedstocks can start with a C/N ratio below 15 and are very unstable. A C/N ratio below 10 supplies Nitrogen,

while a ratio above 20 can deplete Nitrogen from the soil. The rate at which Nitrogen will be released or used by the microbes is 

indicated by the respiration rate (BAC). If the respiration rate is too high the transfer of Nitrogen will not be controlable.

Soluble Nutrients & Salts (EC5 w/w dw - mmhos/cm)

9.7 High salts This value refers to all soluble ions including nutrients, sodium, chloride and some 

soluble organic compounds. The concentration of salts will change due to the release of salts from the organic matter as it degrades,

volatilization of ammonia, decomposition of soluble organics, and conversion of molecular structure. High salts + high AgIndex is 

indicative of a compost high in readily available nutrients. The application rate of these composts should be limited by the optimum 

nutrient value based on soil analysis of the receiving soil. High Salts + low AgIndex is indicative of a compost low in nutrients with 

high concentrations of sodium and/or chloride. Limit the application rate according to the toxicity level of thesodium and/or chloride.

Low salts indicates that the compost can be applied without risking salt toxicity, is likely a good source of organic matter, and that 

nutrients will release slowly over time.

Lime Content (lbs. per ton)

0 Low lime content Compost high in lime or carbonates are often those produced from chicken manure (layers)

ash materials, and lime products. These are excellent products to use on a receiving soil where lime has been recommended by 

soil analysis to raise the pH. Composts with a high lime content should be closely considered for pH requirements when formulating 

potting mixes.

Physical Properties

Percent Ash

57.4 Average ash content Ash is the non-organic fraction of a compost. Most composts contain approximately 50%

ash (dry weight basis). Compost can be high in ash content for many reasons including: excess minerilzation(old compost), 

contamination with soil base material during turning, poor quality feedstock, and soil or mineral products added. Finding the source

and reducing high ash content is often the fastest means to increasing nutrient quality of a compost.

Particle Size % > 6.3 MM (0.25")

5.8 May restrict use Large particles may restrict use for potting soils, golf course topdressings, seed-starter 

mixes, and where a fine size distribution is required. Composts with large particles can still be used as excellent additions to field 

soils, shrub mixes and mulches. 

Particle Size Distribution

Each size fraction is measured by weight, volume and bulk density. These results are particularly relevent with decisions to screen 

or not, and if screening, which size screen to use. The bulk density indicates if the fraction screened is made of light weight organic 

material or heavy mineral material. Removing large mineral material can greatly improve compost quality by increasing nutrient and 

organic concentrations.

INTERPRETATION:

Is Your Compost Stable? Page two of three

Respiration Rate

7.5 Moderate-selected use mg CO2-C/g OM/day

The respiration rate is a measurement of the biodegradation rate of the organic matter in the sample (as received).

The respiration rate is determined by measuring the rate at which CO2 is released under optimized moisture and

temperature conditions. 

Biologically Available Carbon

7.9 Moderate-selected use mg CO2-C/g OM/day

Biologically Available Carbon (BAC) is a measurement of the rate at which CO2 is released under optimized moisture, temperature, 

porosity, nutrients, pH and microbial conditions. If both the RR and the BAC test values are close to the same value, the pile is 

optimized for composting. If both values are high the compost pile just needs more time. If both values are low the compost has 

stabilized and should be moved to curing. BAC test values that are higher than RR indicate that the compost pile has stalled. This 

could be due to anaerobic conditions, lack of available nitrogen due to excessive air converting ammonia to the unavailable nitrate

form, lack of nitrogen or other nutrients due to poor choice of feedstock, pH value out of range, or microbes rendered non-active.

Is Your Compost Mature?

AmmoniaN:NitrateN ratio

67 immature

Composting to stabilize carbon can occur at such a rapid rate that sometimes phytotoxins remain in 

the compost and must be neutralized before using in high concentrations or in high-end uses. This 

Ammonia N ppm step is called curing. Typically ammonia is in excess with the break-down of organic materials resulting

670 immature in an increase in pH. This combination results in a loss of volatile ammonia (it smells). Once this toxic 

Nitrate N ppm ammonia has been reduced and the pH drops, the microbes convert the ammonia to nitrates. A low 

10 immature ammonia + high nitrate score is indicative of a mature compost, however there are many exceptions. 

pH value For example, a compost with a low pH (<7) will retain ammonia, while a compost with high lime content 

6.28 immature can lose ammonia before the organic fraction becomes stable. Composts must first be stable before 

curing indicators apply.

Cucumber Bioassay

100.0 Percent Cucumbers are chosen for this test because they are salt tolerant and very sensitive to ammonia

and organic acid toxicity. Therefore, we can germinate seeds in high concentrations of compost to 

measure phytotoxic effects without soluble salts being the limiting factor. Values above 80% for both percent emergence and 

vigor are indicative of a well-cured compost. Exceptions include very high salts that affect the cucumbers, excessive concentrations 

of nitrates and other nutrients that will be in range when formulated to make a growing media. In addition to testing a 1:1 compost:

vermiculite blend, we also test a diluted 1:3 blend to indicate a more sensitive toxicity level. 

Is Your Compost Safe Regarding Health?

Fecal Coliform

< 1000 / g dry wt. Fecal coliforms can survive in both aerobic and anaerobic conditions and is common in all initial 

compost piles. Most human pathogens occur from fecal matter and all fecal matter is loaded in fecal coliforms. Therefore fecal

coliforms are used as an indicator to determine if the chosen method for pathogen reduction (heat for compost) has met the

requirements of sufficient temperature, time and mixing. If the fecal coliforms are reduced to below 1000 per gram dry wt. it is

assumed all others pathogens are eliminated. Potential problems are that fecal coliform can regrow during the curing phase or

during shipping. This is because the conditions are now more favorable for growth than during the composting process.

Salmonella Bacteria

Less than 3 3 / 4g dry wt. Salmonella is not only another indicator organism but also a toxic microbe. It has been used in the 

case of biosolids industry to determine adequate pathogen reduction. 

Metals

Pass The ten heavy metals listed in the EPA 503 regulations are chosen to determine if compost 

can be applied to ag land and handled without toxic effects. Most high concentrations of heavy metals are derived from

woodwaste feedstock such as chrome-arsenic treated or lead painted demolition wood. Biosolids are rarely a problem. 

Does Your Compost Provide Nutrients or Organic Matter?

Nutrients (N+P2O5+K2O)

3.3 Average nutrient content

This value is the sum of the primary nutrients Nitrogen, Phosphorus and Potassium. Reported units are consistent with those 

found on fertilizer formulations. A sum greater than 5 is indicative of a compost with high nutrient content, and best used to supply

nutrients to a receiving soil. A sum below 2 indicates low nutrient content, and is best-used to improve soil structure via the

addition of organic matter. Most compost falls between 2 and 5.

INTERPRETATION: Page three of three

AgIndex (Nutrients/Na+Cl)

10 Average nutrient ratio Composts with low AgIndex values have high concentrations of sodium and/or chloride

compared to nutrients. Repeated use of a compost with a low AgIndex (< 2) may result in sodium and/or chloride 

acting as the limiting factor compared to nutrients, governing application rates. These composts may be used on well-draining

soils and/or with salt-tolerant plants. Additional nutrients form another source may be needed if the application rate is limited by

sodium or chloride. If the AgIndex is above 10, nutrients optimal for plant growth will be available without concern of sodium and/or

chloride toxicity. Composts with an AgIndex of above 10 are good for increasing nutrient levels for all soils. Most composts score

between 2 and 10. Concentrations of nutrients, sodium, and chloride in the receiving soil should be considered when determining

compost application rates. The AgIndex is a product of feedstock quality. Feedstock from dairy manure, marine waste, industrial 

wastes, and halophytic plants are likely to produce a finished compost with a low AgIndex.

Plant Available Nitrogen (lbs/ton)

6 Average N Provider Plant Available Nitrogen (PAN) is calculated by estimating the release rate of Nitrogen from 

the organic fraction of the compost. This estimate is based on information gathered from the BAC test and measured ammonia and

nitrate values. Despite the PAN value of the compost, additional sources of Nitrogen may be needed during he growing season to offset the Nitrogen demand of the microbes present in the compost. With ample nutrients these microbes can further breakdown organic 

matter in the compost and release bound Nitrogen. Nitrogen demand based on a high C/N ratio is not considered in the PAN calculation

because additional Nitrogen should always be supplemented to the receiving soil when composts with a high C/N ratio are applied.

C/N Ratio

18 Indicates immaturity As a guiding principal, a C/N ratio below 14 indicates maturity and above 14 indicates 

immaturity, however, there are many exceptions. Large woodchips (>6.3mm), bark, and redwood are slow to breakdown and 

therefore can result in a relatively stable product while the C/N ratio value is high. Additionally, some composts with chicken manure 

and/or green grass feedstocks can start with a C/N ratio below 15 and are very unstable. A C/N ratio below 10 supplies Nitrogen,

while a ratio above 20 can deplete Nitrogen from the soil. The rate at which Nitrogen will be released or used by the microbes is 

indicated by the respiration rate (BAC). If the respiration rate is too high the transfer of Nitrogen will not be controlable.

Soluble Nutrients & Salts (EC5 w/w dw - mmhos/cm)

6.8 Average salts This value refers to all soluble ions including nutrients, sodium, chloride and some 

soluble organic compounds. The concentration of salts will change due to the release of salts from the organic matter as it degrades,

volatilization of ammonia, decomposition of soluble organics, and conversion of molecular structure. High salts + high AgIndex is 

indicative of a compost high in readily available nutrients. The application rate of these composts should be limited by the optimum 

nutrient value based on soil analysis of the receiving soil. High Salts + low AgIndex is indicative of a compost low in nutrients with 

high concentrations of sodium and/or chloride. Limit the application rate according to the toxicity level of thesodium and/or chloride.

Low salts indicates that the compost can be applied without risking salt toxicity, is likely a good source of organic matter, and that 

nutrients will release slowly over time.

Lime Content (lbs. per ton)

6.9 Average lime content Compost high in lime or carbonates are often those produced from chicken manure (layers)

ash materials, and lime products. These are excellent products to use on a receiving soil where lime has been recommended by 

soil analysis to raise the pH. Composts with a high lime content should be closely considered for pH requirements when formulating 

potting mixes.

Physical Properties

Percent Ash

57.1 Average ash content Ash is the non-organic fraction of a compost. Most composts contain approximately 50%

ash (dry weight basis). Compost can be high in ash content for many reasons including: excess minerilzation(old compost), 

contamination with soil base material during turning, poor quality feedstock, and soil or mineral products added. Finding the source

and reducing high ash content is often the fastest means to increasing nutrient quality of a compost.

Particle Size % > 6.3 MM (0.25")

3.2 May restrict use Large particles may restrict use for potting soils, golf course topdressings, seed-starter 

mixes, and where a fine size distribution is required. Composts with large particles can still be used as excellent additions to field 

soils, shrub mixes and mulches. 

Particle Size Distribution

Each size fraction is measured by weight, volume and bulk density. These results are particularly relevent with decisions to screen 

or not, and if screening, which size screen to use. The bulk density indicates if the fraction screened is made of light weight organic 

material or heavy mineral material. Removing large mineral material can greatly improve compost quality by increasing nutrient and 

organic concentrations.

Is Your Compost Stable? Page two of three

Respiration Rate

13 High-for mulch mg CO2-C/g OM/day

The respiration rate is a measurement of the biodegradation rate of the organic matter in the sample (as received).

The respiration rate is determined by measuring the rate at which CO2 is released under optimized moisture and

temperature conditions. 

Biologically Available Carbon

14 High-for mulch mg CO2-C/g OM/day

Biologically Available Carbon (BAC) is a measurement of the rate at which CO2 is released under optimized moisture, temperature, 

porosity, nutrients, pH and microbial conditions. If both the RR and the BAC test values are close to the same value, the pile is 

optimized for composting. If both values are high the compost pile just needs more time. If both values are low the compost has 

stabilized and should be moved to curing. BAC test values that are higher than RR indicate that the compost pile has stalled. This 

could be due to anaerobic conditions, lack of available nitrogen due to excessive air converting ammonia to the unavailable nitrate

form, lack of nitrogen or other nutrients due to poor choice of feedstock, pH value out of range, or microbes rendered non-active.

Is Your Compost Mature?

AmmoniaN:NitrateN ratio

39 immature

Composting to stabilize carbon can occur at such a rapid rate that sometimes phytotoxins remain in 

the compost and must be neutralized before using in high concentrations or in high-end uses. This 

Ammonia N ppm step is called curing. Typically ammonia is in excess with the break-down of organic materials resulting

2000 immature in an increase in pH. This combination results in a loss of volatile ammonia (it smells). Once this toxic 

Nitrate N ppm ammonia has been reduced and the pH drops, the microbes convert the ammonia to nitrates. A low 

51 mature ammonia + high nitrate score is indicative of a mature compost, however there are many exceptions. 

pH value For example, a compost with a low pH (<7) will retain ammonia, while a compost with high lime content 

5.03 immature can lose ammonia before the organic fraction becomes stable. Composts must first be stable before 

curing indicators apply.

Cucumber Bioassay

100.0 Percent Cucumbers are chosen for this test because they are salt tolerant and very sensitive to ammonia

and organic acid toxicity. Therefore, we can germinate seeds in high concentrations of compost to 

measure phytotoxic effects without soluble salts being the limiting factor. Values above 80% for both percent emergence and 

vigor are indicative of a well-cured compost. Exceptions include very high salts that affect the cucumbers, excessive concentrations 

of nitrates and other nutrients that will be in range when formulated to make a growing media. In addition to testing a 1:1 compost:

vermiculite blend, we also test a diluted 1:3 blend to indicate a more sensitive toxicity level. 

Is Your Compost Safe Regarding Health?

Fecal Coliform

< 1000 / g dry wt. Fecal coliforms can survive in both aerobic and anaerobic conditions and is common in all initial 

compost piles. Most human pathogens occur from fecal matter and all fecal matter is loaded in fecal coliforms. Therefore fecal

coliforms are used as an indicator to determine if the chosen method for pathogen reduction (heat for compost) has met the

requirements of sufficient temperature, time and mixing. If the fecal coliforms are reduced to below 1000 per gram dry wt. it is

assumed all others pathogens are eliminated. Potential problems are that fecal coliform can regrow during the curing phase or

during shipping. This is because the conditions are now more favorable for growth than during the composting process.

Salmonella Bacteria

Less than 3 3 / 4g dry wt. Salmonella is not only another indicator organism but also a toxic microbe. It has been used in the 

case of biosolids industry to determine adequate pathogen reduction. 

Metals

Pass The ten heavy metals listed in the EPA 503 regulations are chosen to determine if compost 

can be applied to ag land and handled without toxic effects. Most high concentrations of heavy metals are derived from

woodwaste feedstock such as chrome-arsenic treated or lead painted demolition wood. Biosolids are rarely a problem. 

Does Your Compost Provide Nutrients or Organic Matter?

Nutrients (N+P2O5+K2O)

3.6 Average nutrient content

This value is the sum of the primary nutrients Nitrogen, Phosphorus and Potassium. Reported units are consistent with those 

found on fertilizer formulations. A sum greater than 5 is indicative of a compost with high nutrient content, and best used to supply

nutrients to a receiving soil. A sum below 2 indicates low nutrient content, and is best-used to improve soil structure via the

addition of organic matter. Most compost falls between 2 and 5.

INTERPRETATION: Page three of three

AgIndex (Nutrients/Na+Cl)

9 Average nutrient ratio Composts with low AgIndex values have high concentrations of sodium and/or chloride

compared to nutrients. Repeated use of a compost with a low AgIndex (< 2) may result in sodium and/or chloride 

acting as the limiting factor compared to nutrients, governing application rates. These composts may be used on well-draining

soils and/or with salt-tolerant plants. Additional nutrients form another source may be needed if the application rate is limited by

sodium or chloride. If the AgIndex is above 10, nutrients optimal for plant growth will be available without concern of sodium and/or

chloride toxicity. Composts with an AgIndex of above 10 are good for increasing nutrient levels for all soils. Most composts score

between 2 and 10. Concentrations of nutrients, sodium, and chloride in the receiving soil should be considered when determining

compost application rates. The AgIndex is a product of feedstock quality. Feedstock from dairy manure, marine waste, industrial 

wastes, and halophytic plants are likely to produce a finished compost with a low AgIndex.

Plant Available Nitrogen (lbs/ton)

9 Average N Provider Plant Available Nitrogen (PAN) is calculated by estimating the release rate of Nitrogen from 

the organic fraction of the compost. This estimate is based on information gathered from the BAC test and measured ammonia and

nitrate values. Despite the PAN value of the compost, additional sources of Nitrogen may be needed during he growing season to offset the Nitrogen demand of the microbes present in the compost. With ample nutrients these microbes can further breakdown organic 

matter in the compost and release bound Nitrogen. Nitrogen demand based on a high C/N ratio is not considered in the PAN calculation

because additional Nitrogen should always be supplemented to the receiving soil when composts with a high C/N ratio are applied.

C/N Ratio

17 Indicates immaturity As a guiding principal, a C/N ratio below 14 indicates maturity and above 14 indicates 

immaturity, however, there are many exceptions. Large woodchips (>6.3mm), bark, and redwood are slow to breakdown and 

therefore can result in a relatively stable product while the C/N ratio value is high. Additionally, some composts with chicken manure 

and/or green grass feedstocks can start with a C/N ratio below 15 and are very unstable. A C/N ratio below 10 supplies Nitrogen,

while a ratio above 20 can deplete Nitrogen from the soil. The rate at which Nitrogen will be released or used by the microbes is 

indicated by the respiration rate (BAC). If the respiration rate is too high the transfer of Nitrogen will not be controlable.

Soluble Nutrients & Salts (EC5 w/w dw - mmhos/cm)

11 High salts This value refers to all soluble ions including nutrients, sodium, chloride and some 

soluble organic compounds. The concentration of salts will change due to the release of salts from the organic matter as it degrades,

volatilization of ammonia, decomposition of soluble organics, and conversion of molecular structure. High salts + high AgIndex is 

indicative of a compost high in readily available nutrients. The application rate of these composts should be limited by the optimum 

nutrient value based on soil analysis of the receiving soil. High Salts + low AgIndex is indicative of a compost low in nutrients with 

high concentrations of sodium and/or chloride. Limit the application rate according to the toxicity level of thesodium and/or chloride.

Low salts indicates that the compost can be applied without risking salt toxicity, is likely a good source of organic matter, and that 

nutrients will release slowly over time.

Lime Content (lbs. per ton)

0 Low lime content Compost high in lime or carbonates are often those produced from chicken manure (layers)

ash materials, and lime products. These are excellent products to use on a receiving soil where lime has been recommended by 

soil analysis to raise the pH. Composts with a high lime content should be closely considered for pH requirements when formulating 

potting mixes.

Physical Properties

Percent Ash

53.5 Average ash content Ash is the non-organic fraction of a compost. Most composts contain approximately 50%

ash (dry weight basis). Compost can be high in ash content for many reasons including: excess minerilzation(old compost), 

contamination with soil base material during turning, poor quality feedstock, and soil or mineral products added. Finding the source

and reducing high ash content is often the fastest means to increasing nutrient quality of a compost.

Particle Size % > 6.3 MM (0.25")

6.2 May restrict use Large particles may restrict use for potting soils, golf course topdressings, seed-starter 

mixes, and where a fine size distribution is required. Composts with large particles can still be used as excellent additions to field 

soils, shrub mixes and mulches. 

Particle Size Distribution

Each size fraction is measured by weight, volume and bulk density. These results are particularly relevent with decisions to screen 

or not, and if screening, which size screen to use. The bulk density indicates if the fraction screened is made of light weight organic 

material or heavy mineral material. Removing large mineral material can greatly improve compost quality by increasing nutrient and 

organic concentrations.

Respiration Rate

7.5 Moderate-selected use mg CO2-C/g OM/day

matter in the compost and release bound Nitrogen. Nitrogen demand based on a high C/N ratio is not considered in the PAN calculation

because additional Nitrogen should always be supplemented to the receiving soil when composts with a high C/N ratio are applied.

C/N Ratio

15 Indicates immaturity As a guiding principal, a C/N ratio below 14 indicates maturity and above 14 indicates 

immaturity, however, there are many exceptions. Large woodchips (>6.3mm), bark, and redwood are slow to breakdown and 

therefore can result in a relatively stable product while the C/N ratio value is high. Additionally, some composts with chicken manure 

and/or green grass feedstocks can start with a C/N ratio below 15 and are very unstable. A C/N ratio below 10 supplies Nitrogen,

while a ratio above 20 can deplete Nitrogen from the soil. The rate at which Nitrogen will be released or used by the microbes is 

indicated by the respiration rate (BAC). If the respiration rate is too high the transfer of Nitrogen will not be controlable.

Soluble Nutrients & Salts (EC5 w/w dw - mmhos/cm)

7.5 Average salts This value refers to all soluble ions including nutrients, sodium, chloride and some 

soluble organic compounds. The concentration of salts will change due to the release of salts from the organic matter as it degrades,

volatilization of ammonia, decomposition of soluble organics, and conversion of molecular structure. High salts + high AgIndex is 

indicative of a compost high in readily available nutrients. The application rate of these composts should be limited by the optimum 

nutrient value based on soil analysis of the receiving soil. High Salts + low AgIndex is indicative of a compost low in nutrients with 

high concentrations of sodium and/or chloride. Limit the application rate according to the toxicity level of thesodium and/or chloride.

Low salts indicates that the compost can be applied without risking salt toxicity, is likely a good source of organic matter, and that 

nutrients will release slowly over time.

Lime Content (lbs. per ton)

1.8 Low lime content Compost high in lime or carbonates are often those produced from chicken manure (layers)

ash materials, and lime products. These are excellent products to use on a receiving soil where lime has been recommended by 

soil analysis to raise the pH. Composts with a high lime content should be closely considered for pH requirements when formulating 

potting mixes.

Physical Properties

Percent Ash

62.7 High ash content Ash is the non-organic fraction of a compost. Most composts contain approximately 50%

ash (dry weight basis). Compost can be high in ash content for many reasons including: excess minerilzation(old compost), 

contamination with soil base material during turning, poor quality feedstock, and soil or mineral products added. Finding the source

and reducing high ash content is often the fastest means to increasing nutrient quality of a compost.

Particle Size % > 6.3 MM (0.25")

5.9 May restrict use Large particles may restrict use for potting soils, golf course topdressings, seed-starter 

mixes, and where a fine size distribution is required. Composts with large particles can still be used as excellent additions to field 

soils, shrub mixes and mulches. 

Particle Size Distribution

Each size fraction is measured by weight, volume and bulk density. These results are particularly relevent with decisions to screen 

or not, and if screening, which size screen to use. The bulk density indicates if the fraction screened is made of light weight organic 

material or heavy mineral material. Removing large mineral material can greatly improve compost quality by increasing nutrient and 

organic concentrations.

INTERPRETATION:

Is Your Compost Stable? Page two of three

Respiration Rate

6.2 Moderate-selected use mg CO2-C/g OM/day

The respiration rate is a measurement of the biodegradation rate of the organic matter in the sample (as received).

The respiration rate is determined by measuring the rate at which CO2 is released under optimized moisture and

temperature conditions. 

Biologically Available Carbon

7.1 Moderate-selected use mg CO2-C/g OM/day

Biologically Available Carbon (BAC) is a measurement of the rate at which CO2 is released under optimized moisture, temperature, 

porosity, nutrients, pH and microbial conditions. If both the RR and the BAC test values are close to the same value, the pile is 

optimized for composting. If both values are high the compost pile just needs more time. If both values are low the compost has 

stabilized and should be moved to curing. BAC test values that are higher than RR indicate that the compost pile has stalled. This 

could be due to anaerobic conditions, lack of available nitrogen due to excessive air converting ammonia to the unavailable nitrate

form, lack of nitrogen or other nutrients due to poor choice of feedstock, pH value out of range, or microbes rendered non-active.

Is Your Compost Mature?

AmmoniaN:NitrateN ratio

51 immature

Composting to stabilize carbon can occur at such a rapid rate that sometimes phytotoxins remain in 

the compost and must be neutralized before using in high concentrations or in high-end uses. This 

Ammonia N ppm step is called curing. Typically ammonia is in excess with the break-down of organic materials resulting

290 mature in an increase in pH. This combination results in a loss of volatile ammonia (it smells). Once this toxic 

Nitrate N ppm ammonia has been reduced and the pH drops, the microbes convert the ammonia to nitrates. A low 

5.7 immature ammonia + high nitrate score is indicative of a mature compost, however there are many exceptions. 

pH value For example, a compost with a low pH (<7) will retain ammonia, while a compost with high lime content 

7.33 mature can lose ammonia before the organic fraction becomes stable. Composts must first be stable before 

curing indicators apply.

Cucumber Bioassay

100.0 Percent Cucumbers are chosen for this test because they are salt tolerant and very sensitive to ammonia

and organic acid toxicity. Therefore, we can germinate seeds in high concentrations of compost to 

measure phytotoxic effects without soluble salts being the limiting factor. Values above 80% for both percent emergence and 

vigor are indicative of a well-cured compost. Exceptions include very high salts that affect the cucumbers, excessive concentrations 

of nitrates and other nutrients that will be in range when formulated to make a growing media. In addition to testing a 1:1 compost:

vermiculite blend, we also test a diluted 1:3 blend to indicate a more sensitive toxicity level. 

Is Your Compost Safe Regarding Health?

Fecal Coliform

< 1000 / g dry wt. Fecal coliforms can survive in both aerobic and anaerobic conditions and is common in all initial 

compost piles. Most human pathogens occur from fecal matter and all fecal matter is loaded in fecal coliforms. Therefore fecal

coliforms are used as an indicator to determine if the chosen method for pathogen reduction (heat for compost) has met the

requirements of sufficient temperature, time and mixing. If the fecal coliforms are reduced to below 1000 per gram dry wt. it is

assumed all others pathogens are eliminated. Potential problems are that fecal coliform can regrow during the curing phase or

during shipping. This is because the conditions are now more favorable for growth than during the composting process.

Salmonella Bacteria

Less than 3 3 / 4g dry wt. Salmonella is not only another indicator organism but also a toxic microbe. It has been used in the 

case of biosolids industry to determine adequate pathogen reduction. 

Metals

Pass The ten heavy metals listed in the EPA 503 regulations are chosen to determine if compost 

can be applied to ag land and handled without toxic effects. Most high concentrations of heavy metals are derived from

woodwaste feedstock such as chrome-arsenic treated or lead painted demolition wood. Biosolids are rarely a problem. 

Does Your Compost Provide Nutrients or Organic Matter?

Nutrients (N+P2O5+K2O)

3.3 Average nutrient content

This value is the sum of the primary nutrients Nitrogen, Phosphorus and Potassium. Reported units are consistent with those 

found on fertilizer formulations. A sum greater than 5 is indicative of a compost with high nutrient content, and best used to supply

nutrients to a receiving soil. A sum below 2 indicates low nutrient content, and is best-used to improve soil structure via the

addition of organic matter. Most compost falls between 2 and 5.

INTERPRETATION: Page three of three

AgIndex (Nutrients/Na+Cl)

11 High nutrient ratio Composts with low AgIndex values have high concentrations of sodium and/or chloride

compared to nutrients. Repeated use of a compost with a low AgIndex (< 2) may result in sodium and/or chloride 

acting as the limiting factor compared to nutrients, governing application rates. These composts may be used on well-draining

soils and/or with salt-tolerant plants. Additional nutrients form another source may be needed if the application rate is limited by

sodium or chloride. If the AgIndex is above 10, nutrients optimal for plant growth will be available without concern of sodium and/or

chloride toxicity. Composts with an AgIndex of above 10 are good for increasing nutrient levels for all soils. Most composts score

between 2 and 10. Concentrations of nutrients, sodium, and chloride in the receiving soil should be considered when determining

compost application rates. The AgIndex is a product of feedstock quality. Feedstock from dairy manure, marine waste, industrial 

wastes, and halophytic plants are likely to produce a finished compost with a low AgIndex.

Plant Available Nitrogen (lbs/ton)

6 Average N Provider Plant Available Nitrogen (PAN) is calculated by estimating the release rate of Nitrogen from 

the organic fraction of the compost. This estimate is based on information gathered from the BAC test and measured ammonia and

nitrate values. Despite the PAN value of the compost, additional sources of Nitrogen may be needed during he growing season to offset the Nitrogen demand of the microbes present in the compost. With ample nutrients these microbes can further breakdown organic 

matter in the compost and release bound Nitrogen. Nitrogen demand based on a high C/N ratio is not considered in the PAN calculation

because additional Nitrogen should always be supplemented to the receiving soil when composts with a high C/N ratio are applied.

C/N Ratio

14 Indicates maturity As a guiding principal, a C/N ratio below 14 indicates maturity and above 14 indicates 

immaturity, however, there are many exceptions. Large woodchips (>6.3mm), bark, and redwood are slow to breakdown and 

therefore can result in a relatively stable product while the C/N ratio value is high. Additionally, some composts with chicken manure 

and/or green grass feedstocks can start with a C/N ratio below 15 and are very unstable. A C/N ratio below 10 supplies Nitrogen,

while a ratio above 20 can deplete Nitrogen from the soil. The rate at which Nitrogen will be released or used by the microbes is 

indicated by the respiration rate (BAC). If the respiration rate is too high the transfer of Nitrogen will not be controlable.

Soluble Nutrients & Salts (EC5 w/w dw - mmhos/cm)

4.2 Average salts This value refers to all soluble ions including nutrients, sodium, chloride and some 

soluble organic compounds. The concentration of salts will change due to the release of salts from the organic matter as it degrades,

volatilization of ammonia, decomposition of soluble organics, and conversion of molecular structure. High salts + high AgIndex is 

indicative of a compost high in readily available nutrients. The application rate of these composts should be limited by the optimum 

nutrient value based on soil analysis of the receiving soil. High Salts + low AgIndex is indicative of a compost low in nutrients with 

high concentrations of sodium and/or chloride. Limit the application rate according to the toxicity level of thesodium and/or chloride.

Low salts indicates that the compost can be applied without risking salt toxicity, is likely a good source of organic matter, and that 

nutrients will release slowly over time.

Is Your Compost Stable? Page two of three

Respiration Rate

23 High-for mulch mg CO2-C/g OM/day

The respiration rate is a measurement of the biodegradation rate of the organic matter in the sample (as received).

The respiration rate is determined by measuring the rate at which CO2 is released under optimized moisture and

temperature conditions. 

Biologically Available Carbon

23 High-for mulch mg CO2-C/g OM/day

Biologically Available Carbon (BAC) is a measurement of the rate at which CO2 is released under optimized moisture, temperature, 

porosity, nutrients, pH and microbial conditions. If both the RR and the BAC test values are close to the same value, the pile is 

optimized for composting. If both values are high the compost pile just needs more time. If both values are low the compost has 

stabilized and should be moved to curing. BAC test values that are higher than RR indicate that the compost pile has stalled. This 

could be due to anaerobic conditions, lack of available nitrogen due to excessive air converting ammonia to the unavailable nitrate

form, lack of nitrogen or other nutrients due to poor choice of feedstock, pH value out of range, or microbes rendered non-active.

Is Your Compost Mature?

AmmoniaN:NitrateN ratio

35 immature

Composting to stabilize carbon can occur at such a rapid rate that sometimes phytotoxins remain in 

the compost and must be neutralized before using in high concentrations or in high-end uses. This 

Ammonia N ppm step is called curing. Typically ammonia is in excess with the break-down of organic materials resulting

1500 immature in an increase in pH. This combination results in a loss of volatile ammonia (it smells). Once this toxic 

Nitrate N ppm ammonia has been reduced and the pH drops, the microbes convert the ammonia to nitrates. A low 

43 immature ammonia + high nitrate score is indicative of a mature compost, however there are many exceptions. 

pH value For example, a compost with a low pH (<7) will retain ammonia, while a compost with high lime content 

4.71 immature can lose ammonia before the organic fraction becomes stable. Composts must first be stable before 

curing indicators apply.

Cucumber Bioassay

100.0 Percent Cucumbers are chosen for this test because they are salt tolerant and very sensitive to ammonia

and organic acid toxicity. Therefore, we can germinate seeds in high concentrations of compost to 

measure phytotoxic effects without soluble salts being the limiting factor. Values above 80% for both percent emergence and 

vigor are indicative of a well-cured compost. Exceptions include very high salts that affect the cucumbers, excessive concentrations 

of nitrates and other nutrients that will be in range when formulated to make a growing media. In addition to testing a 1:1 compost:

vermiculite blend, we also test a diluted 1:3 blend to indicate a more sensitive toxicity level. 

Is Your Compost Safe Regarding Health?

Fecal Coliform

< 1000 / g dry wt. Fecal coliforms can survive in both aerobic and anaerobic conditions and is common in all initial 

compost piles. Most human pathogens occur from fecal matter and all fecal matter is loaded in fecal coliforms. Therefore fecal

coliforms are used as an indicator to determine if the chosen method for pathogen reduction (heat for compost) has met the

requirements of sufficient temperature, time and mixing. If the fecal coliforms are reduced to below 1000 per gram dry wt. it is

assumed all others pathogens are eliminated. Potential problems are that fecal coliform can regrow during the curing phase or

during shipping. This is because the conditions are now more favorable for growth than during the composting process.

Salmonella Bacteria

Less than 3 3 / 4g dry wt. Salmonella is not only another indicator organism but also a toxic microbe. It has been used in the 

case of biosolids industry to determine adequate pathogen reduction. 

Metals

Pass The ten heavy metals listed in the EPA 503 regulations are chosen to determine if compost 

can be applied to ag land and handled without toxic effects. Most high concentrations of heavy metals are derived from

woodwaste feedstock such as chrome-arsenic treated or lead painted demolition wood. Biosolids are rarely a problem. 

Does Your Compost Provide Nutrients or Organic Matter?

Nutrients (N+P2O5+K2O)

3.6 Average nutrient content

This value is the sum of the primary nutrients Nitrogen, Phosphorus and Potassium. Reported units are consistent with those 

found on fertilizer formulations. A sum greater than 5 is indicative of a compost with high nutrient content, and best used to supply

nutrients to a receiving soil. A sum below 2 indicates low nutrient content, and is best-used to improve soil structure via the

addition of organic matter. Most compost falls between 2 and 5.

INTERPRETATION: Page three of three

AgIndex (Nutrients/Na+Cl)

9 Average nutrient ratio Composts with low AgIndex values have high concentrations of sodium and/or chloride

compared to nutrients. Repeated use of a compost with a low AgIndex (< 2) may result in sodium and/or chloride 

acting as the limiting factor compared to nutrients, governing application rates. These composts may be used on well-draining

soils and/or with salt-tolerant plants. Additional nutrients form another source may be needed if the application rate is limited by

sodium or chloride. If the AgIndex is above 10, nutrients optimal for plant growth will be available without concern of sodium and/or

chloride toxicity. Composts with an AgIndex of above 10 are good for increasing nutrient levels for all soils. Most composts score

between 2 and 10. Concentrations of nutrients, sodium, and chloride in the receiving soil should be considered when determining

compost application rates. The AgIndex is a product of feedstock quality. Feedstock from dairy manure, marine waste, industrial 

wastes, and halophytic plants are likely to produce a finished compost with a low AgIndex.

Plant Available Nitrogen (lbs/ton)

10 Average N Provider Plant Available Nitrogen (PAN) is calculated by estimating the release rate of Nitrogen from 

the organic fraction of the compost. This estimate is based on information gathered from the BAC test and measured ammonia and

nitrate values. Despite the PAN value of the compost, additional sources of Nitrogen may be needed during he growing season to offset the Nitrogen demand of the microbes present in the compost. With ample nutrients these microbes can further breakdown organic 

matter in the compost and release bound Nitrogen. Nitrogen demand based on a high C/N ratio is not considered in the PAN calculation

because additional Nitrogen should always be supplemented to the receiving soil when composts with a high C/N ratio are applied.

C/N Ratio

18 Indicates immaturity As a guiding principal, a C/N ratio below 14 indicates maturity and above 14 indicates 

immaturity, however, there are many exceptions. Large woodchips (>6.3mm), bark, and redwood are slow to breakdown and 

therefore can result in a relatively stable product while the C/N ratio value is high. Additionally, some composts with chicken manure 

and/or green grass feedstocks can start with a C/N ratio below 15 and are very unstable. A C/N ratio below 10 supplies Nitrogen,

while a ratio above 20 can deplete Nitrogen from the soil. The rate at which Nitrogen will be released or used by the microbes is 

indicated by the respiration rate (BAC). If the respiration rate is too high the transfer of Nitrogen will not be controlable.

Soluble Nutrients & Salts (EC5 w/w dw - mmhos/cm)

10 High salts This value refers to all soluble ions including nutrients, sodium, chloride and some 

soluble organic compounds. The concentration of salts will change due to the release of salts from the organic matter as it degrades,

volatilization of ammonia, decomposition of soluble organics, and conversion of molecular structure. High salts + high AgIndex is 

indicative of a compost high in readily available nutrients. The application rate of these composts should be limited by the optimum 

nutrient value based on soil analysis of the receiving soil. High Salts + low AgIndex is indicative of a compost low in nutrients with 

high concentrations of sodium and/or chloride. Limit the application rate according to the toxicity level of thesodium and/or chloride.

Low salts indicates that the compost can be applied without risking salt toxicity, is likely a good source of organic matter, and that 

nutrients will release slowly over time.

Lime Content (lbs. per ton)

0 Low lime content Compost high in lime or carbonates are often those produced from chicken manure (layers)

ash materials, and lime products. These are excellent products to use on a receiving soil where lime has been recommended by 

soil analysis to raise the pH. Composts with a high lime content should be closely considered for pH requirements when formulating 

potting mixes.

Physical Properties

Percent Ash

46.2 Average ash content Ash is the non-organic fraction of a compost. Most composts contain approximately 50%

ash (dry weight basis). Compost can be high in ash content for many reasons including: excess minerilzation(old compost), 

contamination with soil base material during turning, poor quality feedstock, and soil or mineral products added. Finding the source

and reducing high ash content is often the fastest means to increasing nutrient quality of a compost.

Particle Size % > 6.3 MM (0.25")

10.0 May restrict use Large particles may restrict use for potting soils, golf course topdressings, seed-starter 

mixes, and where a fine size distribution is required. Composts with large particles can still be used as excellent additions to field 

soils, shrub mixes and mulches. 

Particle Size Distribution

Each size fraction is measured by weight, volume and bulk density. These results are particularly relevent with decisions to screen 

or not, and if screening, which size screen to use. The bulk density indicates if the fraction screened is made of light weight organic 

material or heavy mineral material. Removing large mineral material can greatly improve compost quality by increasing nutrient and 

organic concentrations. 

Appendix:

Estimated available nutrients for use when calculating application rates

Plant Available Nitrogen (PAN) calculations: lbs/ton (As Rcvd.)

PAN = (X * (organic N)) + ((NH4-N) + (NO3-N))

X value = If BAC < 2 then X = 0.1 Plant Available Nitrogen (PAN) 9.9

If BAC =2.1 to 5 then X = 0.2 Ammonia (NH4-N) 2.00

If BAC =5.1 to 10 then X = 0.3 Nitrate (NO3-N) 0.06

If BAC > 10 then X = 0.4 Available Phosphorus (P2O5*0.64) 5.5

Note: If C/N ratio > 15 additional N should be applied. Available Potassium (K2O) 18.8
