Soil Sampling No-Tillage and Minimum Tillage Fields: Make Nutrient Stratification Work for You
Soil sampling of no-till and minimum till fields will be shown. The spatial consequences of the vertical distribution of nutrients, and soil acidity, will be shown and discussed. A number of examples of different nutrient distributions with soil depth, and the consequences to corn or soybean nutrition and yield will be shared. Economic considerations to nutrient stratification, given certain assumptions, will be noted in terms of the resulting value to soil sampling these fields.
Speaker
John Grove
John Grove is a Professor of Plant and Soil Sciences, based at the University of Kentucky Research and Education Center near Princeton, Kentucky, and is responsible for soil fertility and plant nutrition management research and extension. He has taught nutrient management at both undergraduate and graduate levels. He was born in Michigan and joined the UK faculty in 1981, after training in chemistry and soil chemistry at Michigan State and agronomy at the University of Georgia. His research interests are understanding and management of agricultural soil chemical and physical properties and improving our knowledge of; a) spatial and temporal dynamics in soil nutrient cycling and crop nutrition; b) soil, water and atmosphere quality as related to inorganic/organic nutrient source management; and c) crop and tillage rotations with particular emphasis on the no-tillage system. He has directed/co-directed 30 graduate students (14 Ph.D. and 16 M.S.) to the successful conclusion of their programs.
