What practice is often recommended to prevent runoff of excess fertilizers into waterways?

Cover cropping is an effective practice recommended to prevent the runoff of excess fertilizers into waterways. This method involves planting crops specifically to cover the soil rather than for harvest. The roots of cover crops help to hold the soil in place, reducing erosion and preventing the nutrients from leaching into nearby water bodies. Additionally, cover crops can improve soil health by enhancing organic matter and increasing biodiversity.

By incorporating cover crops into farming systems, farmers can also reduce nutrient runoff because these plants take up excess nitrogen and phosphorus from the soil, making them less available to be washed away with water during rain events. This practice not only protects water quality but also promotes better nutrient management and enhances overall sustainability in agricultural systems.
