New Research Shows Planting Cover Crops can Aid in the Destruction of Weed Seeds

I was aware of many benefits of cover crops but recent research has found one I did not know about.

Purdue University Entomologist Ian Kaplan and Carmen Blubaugh, who earned her doctorate at Purdue and is now a postdoctoral research associate at Washington State University discovered that cover crops provide habitat for beetles and rodents that feed on weed seed and prevent it from becoming part of a “seed bank” in the soil. They found that fields planted to cover crops had three to four times as many weed seeds eliminated due to feeding as those without cover crops.
