### process:

Aeration
* Most aeration increases water infiltrations.
* Some aeration affects metabolism.
* allows oxygen to reach microorganisms that break down the organic matter
  - the soil to expand which helps roots to penetrate deeper and further
  - water to penetrate and nutrients to better reach the root zone
* also helps peat sods to survive and become established
  - to raise the pH by reducing the content of dissolved carbon dioxide
  - keeps nutrients trapped in sediment, preventing release and use by algae
  - makes the water release harmful gasses and pick up oxygen as the bubbles rise
  - occurs when live plants release oxygen as they grow
* bottleneck in many processes in minerals refinement and biotechnology.
* breaks up the soil and allows water to penetrate.
* generally utilizes ambient air.
* helps conserve water by reducing soil compaction, water run-off and puddling
  - oxygen, water, fertilizer, and organic matter to reach roots
  - prevent soil compaction
  - the turf in compacted soils and also allows the surface to drain better
  - to alleviate the compaction caused by winter snows and gravity
* improves soil air exchange which improves fertilizer efficiency and turfgrass rooting.
* increases infiltrations
* involves exposing manure to oxygen and air.
* is also important to seedbed preparation
  - an action
  - energy intensive
  - especially effective against viruses in cattle and pig slurry
  - exactly what it sounds like, the addition to air in water
  - most effective when soil cores are removed from the lawn surface
  - natural processes
* is the addition of air to water
  - most important aspect of soil preparation
  - process by which oxygen is transferred from the air to the water
  - recommendation to loosen the compacted soils
  - recommended method for treatment of public water supplies
  - removal of cores of soil from the lawn
  - replacement of oxygen to the center of the compost pile where it is lacking
  - usually a system of jets or fountains of water, or a system of riffles or waterfalls
* key element in composting.
* occurs by pouring the wine into a larger container, such as a decanter or large wineglass.
* permits air and water with nutrients to penetrate the soil.
* preferred method of treatment for radon in water.
* quickly changes the chemistry of the soil.
* reduces moisture content and keeps soybeans in excellent condition.
* releases hydrogen sulfide and provides an acceptable water supply for the household.
* remedy for compacted soil.
* removes plugs of dirt helping increase water retention and air circulation to grass roots.
* replaces oxygen-deficient air in the center of the compost pile with fresh air.
* saturates water with air, usually by spraying fountains of water into the air.
* significantly increases water uptake and improves the lawn s resistance to drought.
* slow process to remove thatch, which stimulates microbial activity.

### process | aeration:

Core aeration
* can also help increase water infiltration on compacted soils.
* is easiest when the soil is moist
  - the process of mechanically removing plugs of thatch and soil from the lawn
* pulls plugs of soil out and lets air, water and fertilizer into the soil.

Mechanical aeration
* ensures that the natural environment is maintained.
* involves pumping air into a storage structure.
* is the easiest way to mange moisture and temperature in stored grain.

Soil aeration
* Most soil aeration increases infiltrations
* Some soil aeration affects metabolism
  - reduces compaction
* involves more than just spreading or piling the soil and letting it sit.
* is important for water storage and air exchanges
  - the process by which soil air is replaced by atmospheric air
