In this episode of The Crop Science Podcast Show, Dr. John Jones from the University of Illinois Urbana-Champaign explains how phosphorus and potassium recommendations are developed and why nutrient test methods vary by region. He explores nutrient behavior in soils, calibration approaches, and how agronomists can make better data-driven fertilizer decisions. Learn how to fine-tune your nutrient management strategies and why accurate soil testing matters. Listen now on all major platforms!

"We treat phosphorus and potassium as more immobile nutrients that remain in the soil for years or even decades, which makes soil testing a reliable tool for guiding fertilization decisions."

Meet the guest: Dr. John Jones is an Assistant Professor of Agronomy and Soil Fertility Extension Specialist at the University of Illinois Urbana-Champaign. With extensive research experience in soil fertility, plant nutrition, and nutrient management, he focuses on practical strategies for optimizing phosphorus and potassium recommendations in U.S. crop systems.

In this special episode of The Crop Science Podcast Show, celebrating National Corn Month, Dr. Seth Murray from Texas A&M University shares how high-throughput phenotyping and UAV-based data are transforming modern corn breeding. He explores the role of environmental interactions, what drone imagery is revealing about crop traits, and how phenomics is shaping the future of genetic improvement. Listen now on all major platforms!

"We’re starting to model corn height growth over time with UAV data, and it’s more predictive of yield than just taking an end-of-the-season single measurement."

Meet the guest: Dr. Seth Murray holds a Ph.D. in Plant Breeding and Genetics from Cornell University and a B.S. in Crop and Soil Sciences from Michigan State University. As Professor and Eugene Butler Endowed Chair at Texas A&M University, his work focuses on corn breeding, phenomics, and quantitative genetics to improve crop sustainability in challenging southern environments.
