=Introduction=
Compost is a mixture of ingredients used to fertilize and improve soil. Compost is commonly prepared by decomposing plant and food waste and recycling the organic materials. The resulting mixture is rich in plant nutrients and beneficial organisms, such as worms and fungal mycelium.

Compost is used to improve the soil fertility in gardens, landscaping, horticulture, urban agriculture and organic farming. The benefits of compost include providing nutrients to crops as fertilizer, acting as a soil conditioner, increasing the humus or humic acid contents of the soil, and introducing beneficial colonies of microbes that help to suppress pathogens in the soil. The natural interaction of soil, plant roots, and nutrients in compost improves the soil structure, which increases the soil's water retention ability and controls soil erosion. Compost can be used for land and stream reclamation, wetland construction, and landfill cover.
