Keith Kelling, Extension soils scientist and professor at the University of Wisconsin-Madison, has received the Robert E. Wagner Award from the Potash & Phosphate Institute. He was cited for his Extension and applied research programs, which emphasize improved efficiency of purchased nutrients and full crediting of on-farm nutrient sources.

Kelling will donate the $5,000 award stipend to the Leo M. Walsh/Wisconsin Fertilizer and Chemical Association Soil Fertility Distinguished Fellowship (see sidebar).

Kelling”s research on alfalfa responses to potassium rates, sources and timing has created a comprehensive database for determining crop potassium needs based on soil test results. He also studies soil fertility management for vegetable crops, especially potatoes and vegetables grown on organic soils.

Kelling”s work on manure management addresses crucial needs for Wisconsin”s integrated livestock and crop farming systems. He is an authority on non-conventional soil additives; his rigorous field tests of these products allow him to provide producers with accurate information on their effectiveness. For the past 22 years, Kelling has coordinated the Wisconsin Fertilizer, Aglime and Pest Management Conference.

Nominations for the award, which recognizes contributions to profitable, environmentally sound agriculture, were received from throughout the world. Kelling received the award Friday, May 18, from PPI north-central region director Scott Murrell.

The Potash & Phosphate Institute, founded in 1935, is a not-for-profit organization that supports agronomic research and education programs involving sound agricultural use of potash, phosphate and other inputs in a way that is efficient, profitable and protective of the environment.
