Which method is recommended for enhancing soil health in sustainable practices?

Cover cropping is recommended for enhancing soil health in sustainable practices because it contributes multiple benefits that improve soil structure, nutrient content, and biodiversity. When cover crops are grown, they help to protect the soil from erosion, suppress weeds, and enhance water retention. They also contribute organic matter when they decompose, which fosters a healthy soil ecosystem by providing food for beneficial microorganisms. Additionally, certain cover crops can fix nitrogen in the soil, further enriching its fertility without the need for synthetic fertilizers.

In contrast, excessive irrigation can lead to soil erosion and depletion of nutrients, negatively impacting soil health. Crop rotation is beneficial as well, as it can help prevent disease and pest buildup while improving soil fertility; however, cover cropping often has a more immediate impact on soil health when used in conjunction with other sustainable practices. Minimizing organic matter is detrimental to soil health since organic matter is crucial for maintaining soil structure and fertility.
