Organic matter plays a crucial role in enhancing soil health and fertility, primarily by improving soil structure. When organic matter, such as decomposed plant and animal material, is added to the soil, it helps bind soil particles together, promoting the formation of aggregates. This aggregation enhances the porosity and aeration of the soil, allowing for better water infiltration and drainage. Additionally, the improved structure facilitates root penetration, leading to better root development and overall plant growth. Organic matter also provides essential nutrients and encourages beneficial microbial activity in the soil, contributing to a healthy ecosystem that supports plant life.
