Flooding and water quality degradation are significant challenges in Iowa's agricultural watersheds, driven by intensive farming practices and increasingly extreme weather events. Relay cropping, a regenerative farming practice, offers a solution by keeping soil covered and living roots in the ground year-round to reduce runoff and improve soil health. Plus it provides another source of revenue for farmers. Ross Evelsizer of the Northeast Iowa Resource Conservation & Development, explains how relay cropping integrates cereal grains and soybeans in a single growing season, enhancing soil structure and reducing nutrient loss. Farmers like Loran Steinlage of FLOLO Farms have pioneered this method, demonstrating its profitability and environmental benefits, including increased water infiltration and reduced nutrient runoff. Kate Giannini of the Iowa Flood Center highlights research showing relay cropping could reduce flooding by up to 25% in watersheds while significantly improving water quality. Early data also shows farmers can earn higher profits per acre compared to conventional practices. This episode showcases how farmer-driven innovation and partnerships are advancing nature-based solutions to benefit both agriculture and waterways. waterloop is a nonprofit news outlet.
