Organic amendment refers to the practice of adding organic materials, such as compost, manure, or plant residues, to soil to improve its physical, chemical, and biological properties. This method of soil amendment is commonly used in agriculture to enhance soil fertility, increase water retention, improve nutrient availability, and promote healthier plant growth. Organic amendments also help to increase soil microbial activity and diversity, leading to better nutrient cycling and overall soil health. Overall, organic amendments play a crucial role in sustainable agriculture by providing a natural and environmentally friendly way to improve soil quality and productivity.
