Maintaining protective soil cover focuses on keeping soil continuously shielded with plant residues, living vegetation, or organic mulches. This cover reduces erosion by softening the impact of raindrops, improves water infiltration, and limits evaporation. It also enhances soil biology by feeding microorganisms and supporting the formation of organic matter. Living covers, such as cover crops, stabilize soil with their roots, suppress weeds, and improve nutrient cycling. By preventing degradation and maintaining moisture and fertility, coverage is a key practice in sustainable soil management.
