Why is organic matter important in soil management?

Organic matter plays a crucial role in soil management primarily because it helps retain moisture and nutrients. This characteristic is vital for healthy soil, as organic matter improves the soil structure, which enhances its ability to absorb water. When organic matter is incorporated into the soil, it creates spaces between soil particles that allow water to seep in and be stored, making it available for plants during dry periods.

In addition to moisture retention, organic matter acts like a sponge, binding nutrients and preventing them from leaching away with water. This ensures that essential nutrients are available for plant uptake, promoting better growth and crop yields. The presence of organic matter also supports beneficial microbial populations that contribute to nutrient cycling and overall soil health.

While organic matter does contribute to soil bulk density, this is typically not seen as a primary benefit in soil management. Instead, the enhancement of moisture and nutrient retention is a key reason why managing organic matter is a priority in sustainable agricultural practices.
