Studies about cover crops from many of the semi-arid Great Plains have been cautionary or conditional, owing to potential concerns about soil moisture or nutrient use from covers seeded ahead of cash crops.
One expected benefit of using legumes as a cover crop is to provide a source of nitrogen (N) to the cropping system, but in certain situations the amount of fixed N may be lower than anticipated, says University of Nebraska Extension.
A study found that legume covers actually supplied little total nitrogen due to low biomass production, while the nitrogen contained in cereal rye residue was likely readily available for the next corn crop.
Manured fields are good candidates for the pre-sidedress soil nitrate test, but nitrogen credit following legume crops is unpredictable and will likely depend on the stand density and timely termination.
With this year's above average no-till corn height and ear placements 6 feet or higher on the plant, do we still want to pick the corn leaving an average stubble height or should stubble height be higher?
Capturing sunlight and keeping living roots in the ground as long as possible is the goal of Beaver Dam, Ws., no-tiller Marty Weiss. The co-chair of the Dodge County Farmers for Healthy Soil & Healthy Water talks about strip-cropping and interseeding cover crops at a field day in the summer of 2020.

Finding solutions to the problems farmers face is what inspired Harry and Etta Yetter to open a small machine shop in west central Illinois in the 1930s. Today, four generations later, Yetter continues the tradition of solving agricultural problems to meet the needs of producers all over the world.
