A survey of 759 farmers, including growers that attended last winter’s 21st annual National No-Tillage Conference in Indianapolis, sheds new light on the value of cover crops. Conducted by the USDA’s North Central Regional Sustainable Agriculture Research and Education program (SARE) and the Conservation Technology Information Center, the results demonstrate why investing dollars in cover crops is a good strategy.
While many growers utilize more than one tillage practice, 55% of the farmers are following a continuous no-till program, while 19% do rotational no-till. Strip-tillage and vertical tillage are each used by 12% of the growers.
By comparison, only 10% of the growers that filled out the survey are using conventional tillage, while reduced tillage was used by 19%.
The results showed that corn planted after cover crops had a 9.6% yield boost when compared to side-by-side fields without cover crops. Soybean yields jumped nearly 12% following a cover crop.
But the big news occurred in areas of the Corn Belt that were hit hard by last year’s drought. In an extremely dry year, there was a 14.3%…
