Abstract
Composting is the controlled biological process of decomposition and recycling of organic material into a humus-rich soil amendment known as compost. Mixed organic materials such as manure, yard trimmings, food waste and biosolids must go through a controlled heat process before they can be used as high quality, biologically stable and mature compost (otherwise it is just mulch, manure or byproduct). Compost has a variety of uses and is known to improve soil quality and productivity as well as prevent and control erosion.
