Cover Crops for Reducing Herbicides in Soybeans

By Practical Farmers of Iowa


Based on previous on-farm research he has conducted, Sam Bennett of Galva has seen evidence that a cereal rye cover crop can suppress weeds and reduce herbicide inputs in soybeans.

As such, he grew soybeans following a cereal rye cover crop and compared three herbicide packages that varied in residual activity and cost.

Bennett recorded similar soybean yields between the low-cost and full (most expensive) herbicide packages he compared.
