Which agricultural practice is commonly used to enhance soil fertility?

The practice of applying compost and using cover crops is vital for enhancing soil fertility because both techniques contribute significantly to the nutrient content and overall health of the soil. Compost enriches the soil with organic matter and essential nutrients, improving soil structure, moisture retention, and microbial activity. It introduces beneficial microorganisms that help decompose organic matter and make nutrients available for crops.

Cover crops, on the other hand, are planted during off-seasons or periods when the soil would otherwise be bare. They prevent erosion, suppress weeds, and improve soil structure. Additionally, many cover crops, such as legumes, can fix nitrogen in the soil, which is crucial for plant growth. This dual approach ensures a sustainable and healthy soil ecosystem, promoting fertility and enhancing crop productivity over time.

In contrast, practices like monoculture planting can deplete soil nutrients and increase vulnerability to pests and diseases. Overgrazing can lead to soil degradation, while crop rotation, although beneficial, does not directly involve amending the soil as much as the application of compost and cover crops does.
