A Penney For Your Thoughts

Sean and Andrew are back with two of the leading nitrogen experts in the field, Iowa State University’s Dr. Mike Castellano and the University of Illinois Urbana-Champaign’s Dr. Andrew Margenot, to dig into the science of nitrogen in row crop systems. The crew discusses: ✅ The relationship between nitrogen and phosphorus ✅ Trials used to evaluate nitrogen use and loss ✅ How nutrients are lost from the soil and how soil is lost from the field ✅ Responsibly managing inputs in a tight economy ✅ What happens to nitrogen in the soil after application 🌱 Meet the Guests: Originally from Rhode Island, Dr. Mike Castellano obtained his Ph.D from Penn State in soil science. He now is an agronomy professor at Iowa State University, where his research focuses on biogeochemical cycling and transport within the soil as it extends to the atmosphere and subsoil. His ultimate objective is to maximize sustainable productivity of agricultural systems, specifically looking at nitrogen. Dr. Andrew Margenot is originally from Rhode Island and earned his Ph.D in in Soils and Biogeochemistry from the University of California Davis. He is now an associate professor at the University of Illinois Urbana-Champaign, where his work addresses the literal foundation of all cropping systems: soils. Alongside his team, he evaluates how human activities can enhance or compromise soil services to human societies, with an emphasis on food security from urban and rural agroecosystems in the U.S. Midwest and East Africa. A Penney for Your Thoughts is hosted by Sean Blomgren, agronomist and owner of Blomgren Seed from Boone, Iowa, and Andrew Penney, plant doctor and Preceon agronomy lead for Bayer Crop Science from Ames, Iowa. We cover all things agronomy and high-yield management, share what we're seeing in the field and bring in trusted voices from the industry to deliver timely, relevant insights that matter to your farm. It's ag talk that just makes cents. ⭐️ Like what you hear?

Sean and Andrew are joined by Iowa State University’s Dr. Sotirios Archontoulis to discuss his research on the relationship between different generations of corn hybrids and nitrogen variability. The crew discusses: ✅ Managing the impacts of weather during the growing season ✅ Old era vs. new era hybrid research and data collection ✅ Yield efficiency compared to physiological efficiency ✅ Nitrogen supply in relation to post-harvest management practices ✅ GGD and SDD effects on yields 🌱 Meet the Guests: Dr. Sotirios Archontoulis is a professor of integrated cropping systems in the Iowa State University Department of Agronomy. His research aims to predict impacts, explain causes, and design future strategies to improve crop productivity and environmental sustainability. His approach combines field experimentation and use of agricultural systems process-based models to explain Genotype x Environment x Management interactions and enable prediction and design at scale.
