Research Interests :
My primary research interests are nitrogen and phosphorus management in production agriculture.  We conduct field trials to evaluate the use of soil testing, tissue testing, and remote sensing to improve nutrient efficiencies in corn.

I have am also involved in research more directly associated with poultry production including evaluation of sand bedding in poultry houses, tree plantings around confinement units, and evaluation of temporary litter storage structures.

Recent Research

Extension Education Activities:
My primary Extension activity is related to the Delaware Nutrient Management Program.  Along with Dr. Greg Binford, I am responsible for developing and conducting all of the nutrient management training required under the
Delaware law.  As of January, 2004 we have developed 12 different 3-hour classes and have conducted more than 200 classes for this training program.
Other responsibilities include work as Extension Water Quality Coordinator, and Sustainable Agriculture Research and Education (SARE) coordinator.
