Which process is responsible for enriching the soil in grasslands?

The process that enriches the soil in grasslands through grass root decay is crucial for maintaining healthy ecosystems. When grass plants die, their roots decompose, adding organic matter to the soil. This organic matter not only enriches the nutrient content of the soil but also enhances its structure, moisture retention, and overall fertility.

The decay of roots is particularly important in grassland environments, where the majority of plant biomass is below ground. As these roots break down, they release essential nutrients like nitrogen, phosphorus, and potassium into the soil, which are vital for plant growth. Additionally, root decay contributes to soil aeration and provides habitats for soil organisms, further promoting a robust and diverse microbial community.

Overall, grass root decay is a key driver of soil health in grasslands, sustaining the productivity and resilience of these ecosystems over time.
