Cover crops improve soil health, water quality for Iowa farmer

A southwest Iowa farmer says he continues to see positive results from his implementation of cover crops.
Mark Peterson farms near Stanton in Montgomery County. He tells Brownfield that cover crops have helped him reach some of his environmental goals.
“We have done cover crops for a number of years and have been very happy. That’s a big part of keeping our water clean going on through.”
Peterson says cover crops have a direct impact on improving water quality.
“That would be more for our neighbors downstream,” he said. “We’ve got to think downstream, and we’ve got to think about future generations.”
He says cover crops, like cereal rye, have also boosted the health of his soils.
Peterson spoke to Brownfield at the 2025 NAFB Convention.
