Compost is composed of organic materials derived from plant and animal matter that has been decomposed through natural processes. The process of composting is simple and practiced by individuals in their homes, farmers on their land, and industrially by cities and factories. Compost is rich in nutrients and improves any type of soil. It is used in gardens, landscaping, horticulture, and agriculture. The compost itself is beneficial for the land in many ways, including as a soil conditioner, a fertilizer, addition of vital humus, and as a natural pesticide for soil.
