Corn stover to sustain soil organic carbon further constrains biomass supply
Sustainable aboveground crop biomass harvest estimates for cellulosic ethanol production, to date, have been limited by the need for residue to control erosion. Recently, estimates of the amount of corn (Zea mays L.) stover needed to maintain soil carbon, which is responsible for favorable soil properties, were reported (5.25–12.50 Mg ha–1). These estimates indicate stover needed to maintain soil ...

USDA amends BCAP
Last week, the U.S. Department of Agriculture (USDA) issued a final rule amending the Biomass Crop Assistance Program (BCAP) to implement changes required by the 2014 Farm Bill. BCAP provides financial assistance to owners and operators engaged in biomass crops, including collection, harvest, storage, and transportation. The final rule does not alter the scope of the BCAP but does reduce the ...

Aquacrop—the FAO crop model to simulate yield response to water
This article introduces the FAO crop model AquaCrop. It simulates attainable yields of major herbaceous crops as a function of water consumption under rainfed, supplemental, deficit, and full irrigation conditions. The growth engine of AquaCrop is water-driven, in that transpiration is calculated first and translated into biomass using a conservative, crop-specific parameter: the biomass water ...
