About this event
Crop nutrient removal with harvest is often the largest mechanism for nutrient export from crop fields. Accurate and precise removal estimates are necessary for determining fertilizer rates, maintaining optimum soil-test levels and nutrient budgeting.
During this webinar, Dr. Jones will present recent work examining management effects on grain nutrient concentrations and removal rates for corn and soybean. Specifically, how nutrient removal at high yield levels affects fertilization decisions.
Dr. John Jones is a Soil Fertility and Nutrient Management Researcher & Lecturer in the Department of Soil Science at the University of Wisconsin-Madison. Dr. Jones’ research focuses on measuring and managing soil nutrients for agronomic and water quality benefits through soil-test calibration, identifying in what forms nutrients exist in soil and water, and improving nutrient recommendations. He is an alumnus of Kansas State (BSc.) and Iowa State (MSc. & Ph.D.) Universities. John and his family live on their farm near Columbus, WI.
