This document provides guidelines for the proper use and composition of compost. Compost is made from organic waste that improves soil quality and fertility when used in agriculture. It helps retain soil moisture, promotes plant growth, and reduces the need for chemical fertilizers. Using compost in farming decreases environmental pollution and saves money on fertilizer costs.
