In this episode, guests Kristina TeBockhorst, field agricultural engineer, and Joel DeJong, field crops specialist with Iowa State University Extension and Outreach, join Brian Dougherty to discuss optimal timing for fall manure and commercial N applications. Application strategies, yield effects, and adjustments for dry weather and high fertilizer prices are among the topics discussed.
