P & K Insights for Agronomists - Dr. John Jones

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   / john-jones-7951b72b   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.
