ABSTRACT
Compost contains a variety of the basic nutrients that plants require for healthy growth. In addition to the main three; nitrogen, phosphorous, and potassium, of special importance are the micronutrients found in compost such as manganese, copper, iron, and zinc. Composting is a simple way to add nutrient-rich humus which fuels plant growth and restores vitality to depleted soil. In addition, a properly controlled composting environment can ensure production of high temperatures needed for killing weed seeds, diseased plant tissue, and pathogenic organisms. The materials used in compost pile have a major impact on how well the composting process works and the quality of the final compost. There are a number of compostable materials that require special handling before they are put into a backyard pile. Compost additives are not required for successful composting. In some situations, certain additives can be helpful. Here will cover four methods of composting: holding units, turning units, heaps and sheet composting.
