Conservation Takes Teamwork

April 2, 2019

The Roadman family owns a farm in Grundy County on a tributary of the Cedar River that has been in the family for five generations. Years ago, Larry Roadman’s grandfather established Roadman Memorial Park to honor his father.

Harvested winter rye energy cover crop: multiple benefits for North Central US

August 15, 2023

A publication in Bioenergy Research Letters by INRC Director Matt Helmers and others, reports findings of a model-based investigation on the potential benefits of growing winter rye as a cover crop as part of corn-soybean rotations in the North-Central Region of the U.S. They concluded that harvesting fertilized rye CCs before soybean planting in this area could reduce nitrogen loads to the Gulf of Mexico by 27% relative to no cover crops, while providing an estimated 18 million Mg yr−1 of biomass-equivalent to 0.21 EJ yr−1 of biogas energy content (3.5 times the 2022 US cellulosic biofuel production).
