When producers in north-central Ohio talk about MRI, one thing is certain - they're not referring to the elaborate, million-dollar equipment found in hospitals. In this case, MRI stands for Modified Relay Intercropping - an alternative cropping systemthat involves accurately interseeding soybeans into wheat so that two crops are growing in the same field during a crop season. Steven Prochaska, an Ohio State University (OSU) ag extension educator in Crawford County, has researched this system for nearly 15 years. "Relay cropping has been around a long time," he says. "However, MRI is different since it involves planting soybeans (non-polymer coated) into wider wheat rows. MRI soybean planting normally occurs from around June 1-20 - with the goal ofhaving a well-established soybean plant (V2 to V4 growth stage) at wheat harvest."
