I have research and extension interests in the areas of water quality and agricultural drainage. I provide education to diverse groups representing drainage contractors, agricultural producers, water, and the public. My main research goal is to address agricultural water management issues related to non-point source pollution (i.e., excess nitrogen and phosphorous). I am interested in innovative practices that can reduce nutrient load runoff to surface water and conserve water for crop use. Some of these practices are controlled drainage, saturated buffer, drainage water recycling and denitrification bed (a.k.a. woodchip bioreactor). I am also interested in modeling and simulation of the effects of management practices on water quality.
