decomposition - the process of raw materials being broken down into compost by microorganisms.

nitrogenous - material with high levels of nitrogen

carbonaceous - material with high levels of carbon

2torial #0847: Learn2 Make a Compost Pile (continued) Pick your method   Composting uses naturally-occurring microorganisms to transform organic materials into composted materials, and the microorganisms require oxygen, water, warmth, and materials that aren't overly acidic. Once you've constructed the pile, you have options that effect how much time you'll spend on it : On the effort-intensive side of the continuum, you turn the pile frequently, one to three times a day. This aerates the pile--it mixes oxygen into the decaying material. When there is plenty of oxygen, aerobic decomposition takes place and the materials decompose quickly--in as little as three weeks. If you need immediate results and you can find the time, this way is for you is for you. On the other end of the continuum is the long-term method for easygoing, patient people, those who aren't in a hurry and don't want to work too hard. Most of the work is in the construction of the pile; aside from turning the pile once every week or two, you just let it sit! The compost will be ready in about a year or so. If you live in a cold climate, figure about two years. But if you're continuously adding new material to the top, understand that the whole pile won't be ready at once--and this makes harvesting the compost a little trickier.     Step 2
