Current Projects

I oversee all farming and experimental operations at the Wisconsin Integrated Cropping Systems Trial (WICST) in addition to managing a network of bioenergy cropping systems trials throughout WI. WICST is a long-term (29 y), large scale (60 ac) cropping systems experiment designed to evaluate the trade-offs of alternative agricultural productions strategies and issues of agricultural sustainability in organic and conventional farming systems. My current work involves analysis and publication of data from WICST and the bioenergy trials as it pertains to the productivity, profitability, and environmental impact of alternative agricultural production strategies for feed and fuel.

In addition to my research responsibilities I teach two courses for the University of Wisconsin’s 132 year old Farm and Industry Short Course. These courses cover the production and management of grain crops (corn, soybean, wheat) and forage crops (alfalfa, clovers, pasture).

Research and Professional Interests

My primary research interests revolve around the idea of sustainable intensification in Agriculture. Under a model of sustainable intensification the goal is to maintain or increase agricultural productivity while simultaneously improving the ecosystem services provided by an agricultural system (e.g. water filtration, carbon sequestration). There are many approaches and practices that fit this model such as re-integrating crop and livestock production, using cover crops, planting perennial crops such as alfalfa or grasses, and reducing tillage. I am interested in what combinations of such management practices optimize production and sustainability in both organic and conventional cropping systems.
