When managed creatively, cover crops can meet a variety of needs in many different cropping systems. Because many soil and climatic factors will affect the growth and performance of cover crops, growers are urged to conduct small acreage experiments to see which cover crops best meet their local needs. OSU Extension personnel and other University researchers are also good sources for ideas and information. Cover crops can reduce soil erosion from water and wind sources by reducing raindrop impact and water flow rate over the surface. Cover crops increase water infiltration rates and stabilizes soil structure while reducing wind velocity over the soil surface.
Cover crops can also improve soil structure as roots and root exudates promote soil aggregation.
They stimulate microbial activity which also helps to improve soil aggregation. The organic matter provided by cover crops also improves the habitat for earthworms, which create large channels for air and water movement in the soil. This is especially prevalent in reduced-tillage systems. Again, we urge our readers to share their experiences with the entire readership. I again reinterate that this sharing of experineces is the real value of this listserv.
