Turf, ornamental grass, and low, spreading shrubs work best since they cover the soil completely. The protective canopy formed by a cover crop reduces the impact of rain drops on the soil surface thereby decreasing the breakdown of soils aggregates. Plant tall trees around fields to buffer the effects of wind. Legume cover crops, including red clover, crimson clover, lentil and pea, reduced soil loss by 38% to 69% as compared to no cover crops. However, burying sufficient cover crop biomass into the soil in the previous year reduced erosion rates 40 to 90% lower in the next year than maize grown on plots left bare during winter.

They make the soil stay in place by providing cover from the wind and rain between harvests. Cover crops also reduce or eliminate erosion. April 1, 2015. No-till agriculture, which leaves residue on the surface and doesn’t destroy soil aggregates with tillage, can also protect from erosion. Providing coverage of the soil surface and protecting it from rain and wind, Rooting into the soil profile and improving soil structure, Encouraging water infiltration to the soil profile. Cover crops produce more vegetative biomass than volunteer plants; transpire water, increase water infiltration and decrease surface runoff and runoff velocity. Cover crops are added to land to help stabilize the soil, and they help prevent erosion in a few ways.

Displaced soil can carry nutrients, like nitrogen and phosphorus, which further pollute waterways. USDA is an equal opportunity provider and employer. They can also have nutrient benefits. If the velocity of runoff water is doubled in a stream, the carrying capacity of water or the stream competence to transport soil sediment and nutrients increases by a factor of 26. This information is for educational purposes only. These concerns are especially acute in areas where water bodies are not protected by vegetative filters or … We can invest in reduced rates of soil loss from agricultural fields, whether in vineyard rows or corn fields, by planting cover crops, maintaining constant ground cover and utilizing no-till management. Studies have shown decreases in soil loss from fields planted into different types of cover crops. When it rains, water hits the soil at a great impact causing soil to be displaced. The key is to scale up farming practices that build and maintain healthier soil. To have a digest of information delivered straight to your email inbox, visit https://extension.msu.edu/newsletters.

Covering the soil also protects the soil from rainfall splatter. Grass Waterways: By planting grass in areas of concentrated water flow, farmers can prevent much of the soil erosion that results from runoff, as the grass stabilizes the soil while still providing an outlet for drainage. Cover crops prevent soil erosion by improving soil structure and permeability (so that water can seep into the ground more easily, rather than run off the top) and covering the ground (a physical barrier between raindrops and the bare ground). A wind break, such as a wall or hedge, will prevent soil erosion due to wind. Classic purpose of cover crops—to cover the soil to reduce erosion Studies have measured reductions in soil erosion and water runoff Protection of soil surface by living plants and dead residues, even in NT Anchor surface residues, reducing their mvmt.
