Air is needed for composting bacteria to thoroughly break down plant material. Aeration can be accomplished by regular turnings of the compost pile, preferably weekly. A pitch fork or spading fork can be used to turn a pile.
Plastic perforated pipes can be laid throughout the pile to increase air movement.
If the temperature of a pile drops, the compost needs either moisture or aeration.
Ideal compost sizes range from 3x3x3 to 5x5x5. Smaller piles will not generate the heat necessary for plant material to decompose. Larger piles are harder to manage and may not decompose uniformly.
Fertilizer is needed for organic matter to properly decompose. Aerobic bacteria use nitrogen to multiply and break down the organic material.
A couple cups or handfuls of a complete garden fertilizer such as a 10-10- 10, 12-12-12 or 15-15-15 should be added to the compost pile regularly.
Avoid overfertilizing which can kill the decomposing bacteria.
Grass clippings can be composted if weed killers or herbicides have been applied. Herbicides on the market will decompose within a matter of months and not affect the final product.
Lawn weeds, like other plant material, will decompose in a compost pile. Weeds sprayed with herbicides can also be composted with no fear of plant damage from the finished compost.
Old compost recipes called for the addition of limestone when creating the pile. Research has shown that the finished compost has a pH approaching 7. Limestone needs only be added if the compost contains acidic plant material such as evergreen needles.

the biodegradation, usually aerobic and thermophilic, that: involves a heterogeneous organic substrate in the solid state; evolves by passing through a thermophilic stage with a temporary release of phytotoxins; results in the production of carbon dioxide, water, minerals and stabilized organic matter.

Composting Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
Compost ( or ) is organic matter that has been decomposed and recycled as a fertilizer and soil amendment. Compost is a key ingredient in organic farming. At the simplest level, the process of composting simply requires making a heap of wetted organic matter (leaves, "green" food waste) and waiting for the materials to break down into humus after a period of weeks or months. Modern, methodical composting is a multi-step, closely monitored process with measured inputs of water, air, and carbon- and nitrogen-rich materials. The decomposition process is aided by shredding the plant matter, adding water and ensuring proper aeration by regularly turning the mixture. Worms and fungi further break up the material. Aerobic bacteria manage the chemical process by converting the inputs into heat, carbon dioxide and ammonium. The ammonium is further converted by bacteria into plant-nourishing nitrites and nitrates through the process of nitrification.

EPA Terms of Environment
The controlled biological decomposition of organic material in the presence of air to form a humus-like material. Controlled methods of composting include mechanical mixing and aerating, ventilating the materials by dropping them through a vertical series of aerated chambers, or placing the compost in piles out in the open air and mixing it or turning it periodically.
