This webinar will provide a framework to understand how application timing affects choices of fertilizer form and potential losses due to weather phenomena and loss mechanisms; how crop uptake patterns, soil conditions, nutrient source and form, cover crops affect decisions concerning application timing; and how soil, weather, cropping systems and crop characteristics, tillage practices, application timing, fertilizer form, and potential loss factors on affect nutrient placement choices.

Dr. John Grove
Professor - Plant and Soil Sciences Department
University of Kentucky
Dr. John Grove is Professor of Agronomic Soil Science at the University of Kentucky, responsible for teaching nutrient management at both undergraduate and graduate levels and world food issues in the Honors Program. His research interests are in the management of the chemical and physical properties of soils under grain production. Field research involves inorganic/organic source nutrient management (rate, timing, placement); crop species and tillage rotation; and particularly the no-tillage crop establishment/soil management system. That work includes evaluation of spatial and temporal dynamics in nutrient cycling and crop nutrition to give improved nutrient management with greater sustainability and minimal adverse impacts on water quality. Dr. Grove has directed/co-directed more than 28 graduate students (13 Ph.D., 15 M.S.) to completion.
