Research Leader, USDA-ARS Soil & Water Management Unit
Current Research Interests
My research is focused in two major areas.
- The impact of management practices on the cycling of carbon and other greenhouse gases in agricultural systems. Our approach involves field-scale measurement of gas exchange in paired systems, where one field is farmed conventionally while the other is subjected to management practices that are expected to alter greenhouse gas exchange.
- Water management in agricultural systems. This involves a variety of field projects at a number of locations examining the impact of agricultural practices, including cover crops, companion crops, and supplemental irrigation, on water quality and quantity.
