Increasing demand for agricultural commodities such as grain for feed and feedstocks for biofuels are driving rapid land use change. We studied the effect of agricultural land-use change on two historical land use types for three different cropping systems using eddy covariance and ecosystem carbon balance approaches. We quantified the consequences of establishing corn, switchgrass,… More

Eddy covariance measurements were made in seven fields in the Midwest USA over 4 years (including the 2012 drought year) to estimate evapotranspiration (ET) of newly established rain-fed cellulosic and grain biofuel crops. Four of the converted fields had been managed as grasslands under the USDA’s Conservation Reserve Program (CRP) for 22 years, and three had been… More
