A half century of nutrient management focused on nitrogen, phosphorus and potassium, as well as liming, for intensive tillage operations have had its consequences, maintains Joel Gruver. The Western Illinois University fertility specialist will not only look at the impact these practices have had on soils, but he will examine the science of secondary elements and trace elements and the combined impact of soil properties, weather and management practices on their availability to crops.
Gruver will share a critical examination of current techniques for predicting nutrient availability to crops, such as soil and tissue testing, and application strategies for optimizing crop health and yield in no-till systems.
