What is the ecological service that grass performs on a hay field?

Grass in a hay field provides several important ecological services, including soil erosion prevention, carbon sequestration, and habitat for wildlife. Its root systems stabilize the soil, reducing runoff and maintaining soil health. Additionally, grass contributes to biodiversity by supporting various organisms, while also improving air and water quality through its role in the ecosystem. Overall, these services enhance the resilience and sustainability of the agricultural landscape.
