Research results from a study led by Extension specialist Fabian Fernandez at the Rosholt Research Farm in Westport, Minnesota show data from 2016 to 2019 for two cover crop systems: winter rye and Kura clover living mulch. The farm is in the Bonanza Valley and has an irrigation system. Read more in this press release from the University of Minnesota.

Interseeding cover crops into soybean is not a common practice in North Dakota. A study from North Dakota State University Extension evaluated the impact of interseeded winter camelina and winter rye using two soybean varieties with different relative maturities and row spacing.

Iowa State University and USDA researchers found that corn emergence and early growth was significantly reduced when planted within 14 days after winter rye was terminated.

USDA researchers say that winter rye crops seeded in no-till corn-soybean systems have the potential to reduce annual nitrate loss in field drainage by about 18 pounds per acre.

A wealth of scientific information exists on the benefits of cover crops, yet their use in conventional row-crop farming systems traditionally has been low.
