Keith Berns combines over twenty years of no-till farming with ten years of teaching Agriculture and Computers. In addition to using no-till methods on 2,500 acres of irrigated and dryland corn, soybeans, rye, triticale, peas, sunflowers, and buckwheat in South Central Nebraska, he also co-owns and operates Green Cover Seed, one of the major cover crop seed providers and educators in the United States. Through Green Cover Seed, Keith has experimented with over 100 different cover crop types and hundreds of mixes planted into various situations and has learned a great deal about cover crop growth, nitrogen fixation, moisture usage, and grazing utilization of cover crops. Keith also developed the SmartMix Calculator™, one of the most widely used cover crop selection tools. Keith has a Master’s Degree in Agricultural Education from the University of Nebraska and regularly teaches on cover crops and soil health to various groups and audiences.
