What practice can help improve soil organic matter content?

Planting cover crops is a widely recognized practice that significantly contributes to improving soil organic matter content. Cover crops are typically grown during off-seasons when the main crops are not being cultivated. These crops, such as clover, rye, or vetch, play a crucial role in enhancing soil health through several mechanisms.

Firstly, cover crops add organic matter to the soil when they decompose. Their roots and biomass contribute to the soil's organic matter, which is essential for maintaining soil structure, improving moisture retention, and enhancing microbial activity. An increase in organic matter also aids in nutrient availability and supports overall soil fertility.

Additionally, cover crops can prevent soil erosion, reduce nutrient runoff, and suppress weeds, making them a comprehensive approach to soil management. The positive impact of cover crops on soil health aligns with sustainable agricultural practices, promoting better long-term productivity and resilience.

In contrast, practices such as over-irrigation, minimizing crop rotation, and frequent tilling tend to have negative effects on soil organic matter. Over-irrigation can lead to leaching of nutrients, while minimizing crop rotation may reduce the diversity of organic inputs. Frequent tilling disrupts soil structure and can lead to the breakdown of organic matter rather than its enhancement.
