Education:

Ph.D.  University of Nebraska-Lincoln, 1982
M.S.   University of Nebraska-Lincoln, 1978
B.S.    Cornell University, 1974

Research/Extension Area of Emphasis:

Dr. Shapiro emphasizes crop nutrient management in research and public education programs.  Managing nutrients for crop production effectively increases profit for the producer and reduces the potential for off-site contamination.  Recommended practices are derived from research conducted at the Haskell Ag. Lab and on cooperating farmer fields.  Nutrient management takes into account the native fertility of the soil resource, credits from many sources and efficient application methods.
