CNMP Purpose and Conditions

**PURPOSE OF THE CNMP**:

The **Comprehensive Nutrient Management Plan (CNMP)** is a conservation
system for your animal feeding operation. It is designed to address, at
a minimum, the soil erosion and water quality concerns of your
operation. The CNMP encompasses the storage and handling of the manure
as well as the utilization and application of the manure nutrients on
the land.

Manure and Nutrient Management involves managing the source, rate, form,
timing, and placement of nutrients. The practice of nutrient management
serves four major functions:

1.  Supply essential nutrients to soils for plant utilization to produce
    adequate food, forage, and fiber.

2.  Provide for efficient and effective use of scarce nutrient resources
    so they are not wasted.

3.  Help maintain or improve the physical, chemical, and biological
    condition of the soil.

4.  Minimize environmental degradation caused by excess nutrients in the
    environment.

**NITROGEN AND PHOSPHORUS vs. WATER QUALITY**:

The two major nutrients of concern are phosphorus and nitrogen because
they can impact water quality, human health, and animal health. Nitrogen
as nitrate is water soluble and has the potential to leach into ground
water supplies. Nitrogen rich drinking water has potential health
impacts to small babies and to adults if consumed in high quantities.
Surface applied nitrogen, that isn't incorporated, can be lost to the
atmosphere as gaseous ammonia nitrogen and nitrous oxide. Not only does
this loss reduce available crop nutrients but nitrous oxide is a gas
that contributes to the greenhouse effect. Ammonia volatilized to the
atmosphere is also a component of nitrogen-enriched rain, which effects
many things. Ammonia can also be harmful to aquatic life if it becomes
concentrated in levels of 0.02mg/L or greater.

Phosphorus is a concern because when it gets into surface water bodies
it can cause explosive algae blooms and eutrophication in the water
body. This can lead to depressed oxygen levels and fish kills.
Phosphorus is often the limiting nutrient for plants in water bodies, so
when it becomes readily available, plants like algae, thrive and algae
blooms result.

The primary way phosphorus can get into water bodies is through runoff
and erosion. This is especially true if excess phosphorus is surface
applied, as either manure or commercial fertilizer, or if heavy rains
occur just after spreading. Phosphorus can get into water bodies through
erosion because phosphorus tends to attach to soil particles and move
with them. Controlling erosion through erosion control practices,
therefore not only keeps soil in place but also limits the amount of
phosphorus lost to the environment, keeping it available for crop needs.
Controlling erosion is also important since phosphorus tends to
accumulate in the soil from one year to the next. Only 80% of the
phosphorus that is in manure is available to the current crop and the
remaining 20% stays in the soil. This reserve increases each year that
spreading continues at excessive rates if this reserve is not accounted
for with a soil test. Phosphorus can also get into surface water by
being carried in solution as soluble phosphorus. This soluble form is
highly bioavailable and can contribute significantly to eutrophication
even at low levels.

**CONDITIONS**:

The State of New Hampshire DES Water Quality Regulations requires
pollutants (manure, milkhouse waste, silo drainage, non-point sources of
pollution, etc.) to be managed so as not to enter the waters of the
State. Your CNMP provides the basic information on how the wastes
produced from your operation, and/or applied on your fields, will be
utilized. Following your CNMP will keep you in compliance with the State
Water Quality Regulations.

**NOTE:** If the number of livestock change (10% or more), your fields
change, your soil test results change significantly upwards, your
rotation changes, the method of storage changes, or if the method of
application needs to change, contact the NRCS/SWCD office to get this
plan revised.

**Operation and Maintenance:**

-   Maintain the fence around the top of the storage pit.

-   Maintain, repair, or replace warning signs as needed.

-   Check for cracks or shifting of concrete components when pit is
    empty.

-   Monitor the earth berm surrounding the structure periodically for
    burrowing animals, noxious and invasive plant species, small trees
    and shrubs and remove as required.

-   Maintain healthy vegetation on the earth berm.

-   Repair any bare spots or burrows in the earth berm.

-   Waste levels will be monitored during and following unusual storm
    events.

-   As full capacity is approached, enough waste shall be removed at the
    earliest environmentally safe period to ensure that sufficient
    capacity is available to accommodate subsequent storm events.

-   Waste shall be removed from storage and utilized at locations,
    times, and rates in accordance with the Nutrient Management (590)
    developed for this farm.

-   After emptying liquid waste and if needed upon inspection, remove
    the end gate and remove accumulated solids to preserve storage
    capacity. Reinstall and reseal the endgate.

**Preventing Spills:**

-   Don't fill the storage too full.

-   Keep the area mowed around the storage to discourage woodchucks and
    other burrowing animals. Monitor for animal activity, patch holes,
    and remove animals.

-   Make sure end gate is properly installed and tight before filling.

-   Frequently monitor filling of storage, levels before and after
    rainfalls, and loads removed to better manage storage capacity and
    understand capacity changes with each inch of rainfall.

-   Schedule routine maintenance of storage system. Keep written records
    of maintenance.

-   Train employees to drive carefully. Transporting manure can be a
    source of spills. Tanker trailers, and manure spreaders can
    overturn, especially on narrow bridges and steep hills. Be careful
    when applying manure near open waterways.

-   Identify all locations where system failure may occur, how serious a
    problem it may be, and ways to eliminate or stop the source of the
    spill or runoff.

**Spills From Containment Breach or Structure Failure:**

-   Construct earthen dikes or use sawdust bedding or other materials to
    contain or divert spill away from watercourses, roadways, wells,
    lawns etc. Use sawdust bedding to soak up liquid manure where it
    can't be collected and pumped.

-   Set up equipment and procedures to secure the structure from further
    release of manure. Utilize materials on the farm to contain the
    leak.

-   Remove liquid spill from diked areas and low areas with vacuum type
    septic tank pump truck. Remove sawdust and manure with tractor
    loader. Transport to fields for spreading or to another storage.

**Spills From Pumping Operation:**

-   Shut off pumping equipment.

-   Use sawdust bedding or solid manure from pad to divert, or contain
    spill away from watercourses, roadways, and wells and lawns. Use
    sawdust bedding to soak up liquid manure.

-   Remove liquid spill from diked areas and low areas with septic tank
    vacuum pump trucks. Remove sawdust and manure with tractor loader.
    Transport to fields for spreading or to another storage.

####### Spills During Transportation on Public Roadways:

-   Coordinate efforts with local law enforcement and emergency
    personnel.

-   Contain spill or divert manure away from watercourses, roadways or
    improved property.

-   Remove solid manure with a tractor loader, backhoe, or excavator and
    transport to field for spreading.

-   Wash liquid or slurry manure from roadways and public use areas into
    a contained area using a fire truck.

-   Remove liquid spill from contained area with a vacuum type septic
    tank pump truck or front end loader if bedding was used to soak up
    the liquid.

**Spill Reporting:**

-   Notify the local town emergency response personnel (Police or Fire
    Department) if manure spill threatens a water body.

-   Information to provide when calling agencies include: name,
    telephone number, nature of emergency, location of spill including
    address and site description, direction of spill movement, the
    perceived impact, and any control action implemented.

**Clean Up Spill Area:**

-   Remove dike and any materials used.

-   Level any soil disturbance and incorporate any residue.

**Documentation:**

The following should be documented in writing and kept with the
Emergency Action Plan for future reference and emergency response
training:

-   Date, time, location of spill, affected landowners

-   Effect of manure spill on any surface water body or potable water
    well.

-   Approximately how much manure was released and for what duration.

-   Amount of manure, if any, that left the farm property.

-   Any damage done, such as personal injury, fish kill, property
    damage.

-   Cause of the spill.

-   Procedure to handle the emergency.

-   Clean up efforts.

-   List of authorities called, those that responded, and the time it
    took for them to respond.

-   Recommendations to prevent a reoccurrence.

**ODOR CONTROL:**

Barns should be routinely cleaned and bedding applied.

The stored manure, both liquid and solid, should not be disturbed until
the time it is loaded for spreading.

Manure spread on land to be tilled should be incorporated as soon as
possible to capture the ammonia-N.

Avoid spreading around holidays and on weekends when the weather is
sunny and mild and neighbors are out and about.

Take the direction of the wind in consideration when spreading manure.
Do not spread when the wind is blowing towards a neighbors home.

**PEST CONTROL:**

The stored manure, both liquid and solid, should not be disturbed until
the time it is to be loaded for spreading.

A fly control program should be followed around the buildings and manure
piles especially during warm weather.

Flies and other pests are to be controlled using materials and methods
currently recommended by the Cooperative Extension Service.

Read the label before mixing and applying the spray materials. The label
is the law.

The applicator must wear the protective equipment required by the label.

**NUTRIENT MANAGEMENT PLAN**

**OVERVIEW**:

Nutrient Management is managing the source, rate, form, timing,
placement and utilization of manure, other organic by-products,
bio-solids, and other nutrients in the soil and residues. The goal is to
effectively and efficiently use the nutrient resources to adequately
supply soils for plants to produce food, forage, fiber, and cover while
minimizing the transport of nutrients to ground and surface water and
environmental degradation.

The potential environmental and health risks that can occur from
excessive levels of nitrogen and phosphorus are the reasons for nutrient
management. Nutrient Management plans are intended to prevent nutrients
supplied for production purposes from contributing to water quality
impairment. Nutrient Management plans also aim to adequately meet the
crop nutrient requirements with nutrients produced on the farm to
minimize the amounts of fertilizer that must be purchased.

**General Recommendations**:

*The following are broad-based recommendations that should be considered
when applying nutrients on crop, vegetable, or hay fields. They may not
all be applicable for your operation as they are general recommendations
for everyone.*

-   Timing of nutrient applications:

```{=html}
<!-- -->
```
-   Time applications to correspond as closely as possible with plant
    nutrient uptake, while considering cropping system limitations,
    weather and climatic conditions, and field accessibility. Consider
    splitting applications of nitrogen to provide it at the times of
    maximum crop needs.

-   Time applications of animal manure to minimize odors to downwind
    neighbors. Do not spread when it is real windy or when you can not
    incorporate soon after spreading.

-   Time applications to minimize potential runoff if rainfall is
    forecasted within 24 hours. Do not spread if you can not incorporate
    before rainfall occurs.

-   If manure is to be spread on soils subject to flooding they should
    either be plowed down immediately or spread after the danger of
    flooding is minimal (about mid-June).

-   Nutrients should not be applied to flooded or saturated soils when
    the potential for soil compaction and the creation of ruts is high.

```{=html}
<!-- -->
```
-   If spreading in the fall is necessary avoid sloping fields.

-   Use of cover crops:

```{=html}
<!-- -->
```
-   Consider using cover crops whenever possible to tie up and recycle
    residual nitrogen in the soil. Cover crops also serve to trap
    phosphorus during periods of runoff.

-   Fields with high intensity cropping cycles (for example corn or
    another tilled crop every year) should have a cover crop planted to
    take up some of the excess phosphorus in the soil.

-   When spreading manure in the fall on tilled land, incorporate and
    plant a cover crop to reduce potential runoff and erosion.

```{=html}
<!-- -->
```
-   Erosion control and management of runoff water should be practiced
    to prevent pollution of surface waters.

```{=html}
<!-- -->
```
-   Do not spread directly in diversion channels, grassed waterways, or
    other areas of concentrated flow.

```{=html}
<!-- -->
```
-   Establish and maintain vegetated setbacks from environmentally
    sensitive areas such as sinkholes, wells, gullies, perennial
    streams, and waterbodies. The vegetation will act as a filter and
    prevent pollutants and excess nutrients from entering the sensitive
    area(s). Distances of 15 to 150 feet, depending on site conditions,
    can greatly improve water quality.

```{=html}
<!-- -->
```
-   If nitrogen needs to be conserved because allowable application
    rates are limited, spread only when it can be incorporated that day.
    This will reduce the amount lost to volatilization.

-   Other nutrients besides nitrogen, phosphorus, and potassium are to
    be applied at rates consistent with soil test results and/or
    Cooperative Extension recommendations.

```{=html}
<!-- -->
```
-   Consider potential affects to National Register listed or eligible
    cultural resources and listed threatened or endangered species.

```{=html}
<!-- -->
```
-   A cropping sequence using a variety of crop types (grasses, legumes,
    summer annuals, winter annuals, or perennials) with various rooting
    characteristics (shallow roots, deep roots, fibrous root system, tap
    root) will better utilize the available nutrients in the soil over
    several years.

```{=html}
<!-- -->
```
-   Adjusting nutrient inputs based on the current levels of nutrients
    available and amount required for crop production is the best way to
    maintain crop production and avoid excess accumulations. Complete
    soil tests annually to measure the current levels of nutrients in
    the soil. Test manure and other organic material to obtain the
    nutrient content of that source. Add in any atmospheric deposition
    and nitrogen credits from previous legume crops to get the total
    nutrients available.

**HOW PLAN WAS DEVELOPED**:

The Nutrient Management Plan was developed according to the following 10
steps:

1)  A farm resource inventory was conducted. *This involved---*

    a.  Documenting the short and long term nutrient management goals

    b.  Collecting field aerial photos, soils maps, and any other
        conservation plans (HEL plans for example)

    c.  Organizing existing field information such as crop and manure
        history, soil tests, crop yield potentials, etc.

    d.  Conducting a whole-farm field-by-field environmental assessment
        to locate environmentally sensitive features such as: proximity
        to wells and streams, shallow bedrock, leaching and runoff
        potential of soils, soil loss calculations, etc.

    e.  Estimating the whole farm manure production and nutrient value
        if the farm has livestock

    f.  Calculating an approximate whole-farm nutrient budget to
        estimate the balance between land base and manure produced

2)  The overall cropping plan was established for the years that the
    nutrient management plan is intended to support the whole farm
    goals. This included the crops to be grown on each field, the
    planned rotation, tillage measures, realistic yield expectations,
    etc.

3)  Manure was sampled and analyzed

4)  Soil sampling was done and submitted for routine soil testing

5)  A Phosphorus Risk assessment was completed for all fields to
    determine if the nutrient budget should be balanced for nitrogen or
    phosphorus.

6)  Fields were evaluated by soil type to determine if there was a
    threat for nitrogen leaching. High-risk fields were noted for less
    nitrogen to be applied.

7)  Fields were prioritized for manure and other nutrient application
    based on crop needs and environmental assessment results.

8)  The manure application rate, or fertilizer rate, was then determined
    as well as the timing and method of application for each individual
    field using the recommendations from the soil test reports, the
    manure analysis, and the field resource inventory (including the P
    index and nitrogen leaching potentials).

9)  Any additional fertilizer and/or aglime amounts were determined

10) Crop and nutrient spreading record keeping systems were established

**Attached you will find your current nutrient management plan and the
subsequent spreading recommendations that were developed using the
previous ten steps. Please note the setbacks and other concerns per
field. Also please remember that this is a plan that can change. It will
have to be updated according to soil test results, new agricultural
research, different Cooperative Extension recommendations, manure tests,
different legume credits, different crop rotations, etc. It is also a
plan that was developed according to the requirements of the current
NRCS 590 standard and any applicable Federal, state, or local
regulations or policies; and that changes in any of these requirements
may necessitate a revision of the plan.**

**[Method, Form and Planned Timing of Application:]{.underline}**

**Operation and Maintenance**:

1)  Calibrate application equipment to ensure uniform distribution of
    material at planned rates.

2)  Maintain pH levels so that crops have the optimum ability to utilize
    the nutrients.

3)  Conduct soil and manure tests according to the schedule established
    in your nutrient management plan.

4)  Document the actual rate at which nutrients were applied in each
    field. When the actual rates used differ from the recommended and
    planned rates, records will indicate the reason for the differences.

5)  Conduct a periodic plan review to determine if adjustments or
    modifications to the plan are needed. As a minimum, plans will be
    reviewed and revised with each soil test cycle. Plans should be
    reviewed and revised as necessary when changes occur with crop
    types, animal number changes, land base changes, etc. Document the
    dates of any plan reviews, the person performing the review, and
    recommendations that resulted from the review.

6)  Maintain records to document plan implementation. Applicable records
    include:

    a.  Soil test results and recommendations for nutrient application

    b.  Quantities, analyses and sources of nutrients applied

    c.  Dates and method of nutrient applications

    d.  Crops planted, planting and harvest dates, yields, and crop
        residues removed

    e.  Results of water, plant, and/or organic by-product analysis

7)  Records should be maintained for at least five years; or for a
    period longer than five years if required by state, Federal, or
    local ordinances; or program or contract requirements.

8)  Protect fertilizer and organic by-product storage facilities from
    weather and accidental spillage or leakage.

9)  Workers should be protected from and avoid unnecessary contact with
    chemical fertilizers and organic by-products. Protection should
    include the use of protective clothing when working with plant
    nutrients. Extra caution must be taken when handling ammonia sources
    of nutrients, or when dealing with organic wastes stored in
    unventilated enclosures.

10) The disposal of material generated from cleaning nutrient
    application equipment should be spread on cropland according to
    label directions. Excess material should be collected and stored or
    field applied in an appropriate manner. Excess material should not
    be applied on areas of high potential risk for runoff and leaching.

11) The disposal or recycling of nutrient containers should be done
    according to state and local guidelines or regulations.

**Testing Your Soil**

***What is a Soil Test?***

A routine soil test is a tool to manage the mineral nutrition of growing
plants. It is a quick and inexpensive way to check the levels of
essential soil nutrients. Soil is sampled and sent to a lab for
analysis.

***Why Test the Soil?***

Homeowners, farmers and others often test soil from their gardens, yards
and fields. The soil tests tell them soil pH and the level of nutrients
that are available for plant growth.

The pH of the soil is a measurement of relative acidity. Soils that are
too acid are not suitable for most plants.

The amount and balance of nutrients in the soil has an effect on plant
growth, too. Low levels slow plant growth. High levels can pollute the
environment or cause imbalances. A soil test lets you know if you need
to add more nutrients and how much, if any, to add. It can save you
money and prevent water pollution.

***What Information Does a Soil Test Provide?***

The soil test will tell you:

\* the soil pH;

\* levels of potassium (K), phosphorus (P), calcium (Ca), magnesium
(Mg);

\* organic matter level;

\* if there is lead contamination;

\* how much lime and fertilizer (organic or chemical) to add; and

\* other management tips for growing your crop.

***How Often Should I Test the Soil?***

Test your soil at least once every three years. Keep the test results
handy so you can monitor any changes in soil fertility. You may want to
test more often if you have a problem area or if you've applied lots of
nutrients. Some people test their soil every year to save money on
fertilizer, lime and other soil amendments. How often you test depends
on the value of the

crop and how closely you manage it.

Appendix A

***What Time of Year Should I Test My Soil?***

Recommendations are made for the next growing season, so you should test
soil well before the growing season, such as early spring (after the
frost is out of the soil) or in the fall before

the ground freezes. A soil test usually takes two to three weeks (from
shipping to the lab to return of results). Fall sampling will give the
same results as spring sampling. With fall sampling, you will get
results back in plenty of time for planting.

***How Do I Take a Good Soil Sample?***

1.  Get a New Hampshire Soil Testing Information Sheet, bags, and tags
    Analytical Services Lab at the University of New Hampshire,
    Spaulding Life Science Center, Room G-54, Durham, NH 03824. Phone
    number 603-862-3210 and email <Soil.Testing@unh.edu> You can also go
    to the following web site to download the appropriate forms and cost
    data instead of sending for the testing information:
    <http://aslan.unh.edu/UNHSoilTesting/Index.htm>

2\. Use a clean spade, trowel or soil probe to sample the soil. Take
several *cores* (approximately 1 cup of material per core) in different
spots to fully represent the garden or field. Collect one sample for
each 20 acres (or 1 per field for small fields unless they contain
similar soils and cropping patterns). For agricultural fields, take a
minimum of one *core* per acre to make up the sample for the field. You
will want to sample at rooting zone depth (usually six to eight inches
for gardens or fields and three to four inches for sod or turf). Use a
clean container to combine all of the *cores* to make up each sample.
For agricultural fields, collect a subsurface sample made up of 6 to 8
*cores* per 20 acres at depths of 10 to 24 inches to test for nitrates
in the subsurface zone which is still available for plant use.

3\. Mix the soil thoroughly and fill the sample container with soil.

4\. Label the container with your name, address and sample
identification.

5\. Fill out the information form as completely as possible.

6\. Make a copy of the form for your records.

7\. Put the sample container(s) and information (with check or money
order) in a mailing container and mail to the address noted above.

***How do I use the Soil Test Information?***

Soil test analyses are reported as parts per million (ppm). The results
are interpreted by test category and adjusted by soil: very low (VL),
low (L), optimum (Opt), high (H), and very high (VH). The optimum
category is the most profitable category to maintain over time. The low
and very low categories indicate deficient soil test levels, while the
high and very high categories indicate a higher test level than required
for crop production.

Nutrient applications with soil test levels in the H and VH categories
seldom generate a profitable yield response. The very high soil test
category indicates that the nutrient concentration exceeds crop needs,
and further additions of that nutrient very seldom produce a profitable
yield response and may lead to environmental degradation or potential
water quality problems in the area.

**How to Sample Manure for Nutrient Analysis**

***Why Sample?***

A field-by-field nutrient management program requires that multiple
practices be implemented to maintain adequate fertility for crop growth
and development. The program includes soil sampling for soil test
analysis, crop rotation, and giving appropriate nutrient credit to
legumes in the rotation. Manure sampling and manure spreader calibration
are part of a comprehensive nutrient management program so manure can be
credited effectively as a nutrient source. A well-designed soil sampling
plan, along with manure sampling and nutrient analysis, can reduce input
costs and the potential of environmental pollution.

One of the many factors affecting the nutrient content of manure is how
the manure is handled and stored. Each handling system results in
different types of nutrient losses - some unavoidable and others that
can be controlled to a certain degree. The most important thing in
collecting a manure sample is that it should be obtained in a similar
way to the method used in developing standard nutrient value
recommendations. The following guidelines are designed for collecting
on-farm animal manure samples.

***When do I Collect a Manure Sample?***

Sample manure at the time of land application or as close as possible to
application. Sampling at the time of land application will not provide
manure nutrient recommendations that can be used at that time to adjust
the amount of manure applied. The results, however, can be used for
subsequent manure applications and to adjust commercial fertilizer
application. Take manure samples every three to five years after
establishing a base level or if animal management practices change
significantly from present methods. If you apply manure several times a
year, take samples when you plan to apply the bulk of manure. For
example, sample in the spring when manure that has accumulated all
winter will be used as a nutrient source.

Manure sampling should be done in the field as manure is land applied.
This ensures that losses that occur during handling, storage, and
application are taken into account.

***How do I Collect a Manure Sample from the Field?***

Manure accumulates in different types of livestock holding areas. These
areas include barns and other similar housing - where manure is
collected in gutters or in dry stacks - and open paved feedlots. It is
recommended that manure from holding areas should be sampled during
field application. Collect manure samples according to the following
field sampling procedure.

1.  Spread a sheet of plastic or tarp on the field. A 10 feet by 10 feet
    sheet works well for sampling manure.

2.  Drive the tractor and manure spreader over the top of the plastic
    sheet to spread manure over the sheet.

3.  Collect a manure sample using the hand-and-bag method described in
    the following section.

**[Dry or Solid Sample Preparations]{.underline}**

The technique for collecting all solid manure samples is the
hand-and-bag method. It is recommended a minimum of three subsamples be
taken to obtain a representative sample of manure. When making nutrient
recommendations, use an average of the three subsamples.

To collect samples, place a one-gallon resealable freezer bag turned
inside out over one hand. Grab a handful of manure with the covered hand
and turn the freezer bag right side out over the sample with the free
hand. Seal the bag and place it in another freezer bag to prevent leaks.
Label the bag for identification and **freeze** it immediately to
prevent nutrient losses and minimize odors. Manure samples should be
mailed or delivered to the laboratory as soon as possible.

**[Liquid Manure Sampling]{.underline}**

Every effort should be made when sampling to agitate manure in the
storage facility so a representative sample is obtained for laboratory
analysis.

1.  Immediately after filling the tank spreader, use a clean plastic
    pail to collect manure from the unloading port or the opening near
    the bottom of the tank. Be sure the port or opening does not have a
    solids accumulation.

2.  Ensure that the manure in the pail is well-stirred and immediately
    fill a one-quart plastic sample bottle to within one inch from the
    top. Only one sample is necessary for liquid manure.

3.  Be sure to put your name, date, and storage pit identification on
    the bottle.

4.  If the sample cannot be transported to a laboratory within a few
    hours, it should be frozen. Place the container in a tightly sealed
    bag and keep cool until it can be taken to the laboratory.

Sampling from storage facilities directly is not recommended because of
safety considerations and the difficulty of obtaining good
representative samples. Manure stored outside in a solid waste storage
facility or in a field stack is best sampled using the method described
above for Dry or Solid Manure. Samples from the stack can be taken if
collected from various locations within and along the sides for the
stack, mixed and sampled using the hand-and-bag method described above.
Three subsamples should be collected and averaged for the stack.

***What will the Laboratory Analysis give me?***

Manure samples should be sent to the lab for chemical analysis as
quickly as possible to avoid nutrient losses. Basic manure analyses
determined by the laboratory includes total Kjeldahl nitrogen (TKN),
phosphate (P~2~O~5~), and potash (K~2~O).

Results from commercial laboratories are presented as a percent of the
sample weight, as pounds per ton or in pounds per 1,000 gallons of
manure. In any case, manure values from commercial laboratories express
nutrients as the total amount of nutrient available in the manure
sample. Primary nutrients (N, P, and K) are not all available for plant
growth the first year manure is applied. A portion of some nutrients is
present in manure in an organic form and unavailable for plant uptake.
Organic nutrients require transformation to an inorganic state to be
available for plant uptake.

This transformation is dependent on temperature, moisture, chemical
environment, and time. Availability of nutrients can be limited by field
losses, which are affected by types of manure and by manure application
methods. These losses are not accounted for in laboratory results. Refer
to the NRCS Practice Standard 590 - Nutrient Management for information
on availability based on application and incorporation data.

In New Hampshire, manure samples need to be sent to the following
address for analysis: University of Vermont, Agricultural and
Environmental Testing Lab, 219 Hills Building, Burlington, VT
05405-0082. Phone number is 802-656-3030.

**Appendix C**

**Application Equipment Calibration**:

Include the appropriate calibration procedures and delete those that do
not apply.

**Commercial Fertilizer Application Equipment Calibration:**

The nitrogen applicator, the commercial broadcast spreaders, and corn
planter will be set per the manufacturers recommendations then filled
with an known amount and checked over known acreage. Adjustments will be
made to achieve the planned rates.

**Manure Spreader Calibration**

There are several methods that can be used to calibrate the application
rate of a manure spreader. The two best methods are the load-area method
and the plastic sheet method. It is desirable to repeat the calibration
procedure 2 to 3 times and average the results to establish a more
accurate calibration.

Before calibrating a manure spreader, the spreader settings such as
splash plates should be adjusted so that the spread is uniform. Most
spreaders tend to deposit more manure near the spreader than at the edge
of the spread pattern. Overlapping can make the overall application more
uniform. Calibrating of application rates when overlapping requires
measuring the width of two spreads and dividing by two to get the
effective spread width.

Calibration should take place annually or whenever manure is being
applied from a different source or consistency.

**Load-Area Method**

The load-area method is the most accurate and can be used for most types
of manure handling. This method consists of determining the amount
(volume or weight) of manure in a spreader and the total area over which
it is applied. The most accurate method to determine the amount of
manure in a spreader is to weigh the spreader when it is full of manure
and again when it is empty (portable pad scales work well for this). The
difference is the quantity of manure applied over the area covered.
Spreader capacities listed by the manufacturers can be used to determine
the amount of manure in the spreader. However care must be taken when
using manufactures spreader capacities. Heaped loads, loading methods
and manure type may vary considerably from what is listed by
manufacturers of box and side delivery manure spreaders. Spreader
capacities for liquid tankers are accurate provided the tanker is filled
to the manufactures recommended levels, and no foam is present in the
tank.

The area of spread is determined from measuring the length and width of
the spread pattern. Measuring can be done with a measuring wheel,
measuring tape or by pacing.

The application rate is calculated by dividing the amount of manure in
the spreader (Tons or gallons) by the area it is spread over (square
feet) times 43,560 sq. ft./acre.

**Formula:** [Spreader capacity (tons or gallons]{.underline}) X 43560
sq. ft/acre = Application Rate tons or Gallons/Acre

Distance traveled X Spreading width

**Plastic Sheet Method**

The plastic sheet method can only be used with solid or semi-solid
manure. This method of calibrating spreader application rates involves
**1)** cutting a plastic sheet to the specified dimensions (56 inches X
56 inches), **2)** weighing the clean plastic sheet, **3)** laying out
the plastic sheet on the ground and driving the manure spreader
(applying manure at a recorded speed and spreader setting) over the
sheet, **4)** weighing the plastic sheet with the manure on it, and
**4)** determine the net weight of the manure on the sheet (weight of
manure and sheet - weight of the clean sheet), and **5)** the net pounds
of manure equals tons per acre applied.

When calibrating manure spreaders, all details regarding tractor speed
and manure spreader settings and date(s) of each calibration should be
recorded with manure application information, and directly on the
equipment. Mark equipment to ensure a known application rate is applied
each time the referenced tractor speed and spreader settings are used.
Manure spreader settings can include such things as: fast and slow
settings on some box spreaders, gate position on side delivery spreaders
and splash plate position and fill levels on liquid tankers.
