A field event held at Iowa State University’s Sorenson Farm near Boone, Iowa, brought together around 40 farmers, researchers, students, and industry experts to learn about relay cropping. This innovative farming method is gaining attention for its ability to increase farm income, improve soil health, and promote sustainability.
The event was organized by Iowa State University and the Iowa Soybean Research Center. Researchers shared their ongoing work on relay cropping systems, which involve planting a second crop before the first one is harvested. This allows farmers to produce two crops from the same land in a single season.
"We are trying to implement new agricultural systems in Iowa to bring biodiversity, provide another profitable option for farmers, and improve soil health," Arias told attendees during opening remarks.
The research focuses on combining soybeans with crops like cereal rye and winter camelina. These systems are studied to understand their effect on plant health, soil quality, and overall productivity.
"Having cereals and oilseeds provides multiple benefits," Navi said. "It helps to minimize weed infestations, reduce soil erosion, improve soil health, and provide additional income opportunities because farmers can harvest two crops from the same piece of land."
Farmers are also seeing practical advantages. Jason Russell, an Iowa farmer, shared his experience. "We've seen lower chemical costs, less need for spraying, and additional revenue from both the rye and soybean crops," Russell said. "In our best years, we've had comparable soybean yields while also harvesting a cereal rye crop. That's a win-win."
He also added, "When people ask how much rain we got, I tell them all of it," Russell joked. "It soaked in instead of running off."
Technology is also playing a big role. Experts demonstrated drones and sensors that help monitor crop health and improve farm decisions. "Technology is getting cheaper and more accessible," said Fernando Mauri Marcos of the Remote Sensing and Imaging Lab. "The challenge now is making data processing faster so farmers can use the information to make management decisions in real time."
Winter camelina is another focus crop. "The goal is to harvest two crops in one season while improving environmental outcomes," Leavitt said.
With growing demand for sustainable fuel, this crop offers new income. "Customers are looking for low-carbon feedstocks, and intermediate oilseed crops like camelina can help meet that demand without taking land away from existing food production systems," Teeter said.
"Our goal is to explore systems that maintain soybean production while improving environmental outcomes," said Mark Licht.
"This is why we do field days," Navi said. "We want to share what we're learning, hear feedback from farmers and industry, and work together to develop systems that can benefit agriculture in Iowa and beyond."
