Project Number: 1902-21000-007-18
Project Type: Specific Cooperative Agreement

Start Date: Oct 01, 2010
End Date: Feb 28, 2012

Objective:
Spatial analysis of N2O emissions, NO3 leaching, and soil carbon of bioenergy cropping systems from farm to regional and national scale.

Approach:
USDA-ARS and Colorado State University (CSU) will conduct systems analysis of bioenergy crops. Spatial analysis of soil carbon, N2O emissions, and NO3 leaching in bioenergy cropping systems will be conducted over a range of landscape scales from farm, state, region, and national scale. This analysis will quantify the impact of the addition of winter double crops, such as barley, wheat, and rye, to corn and soybean rotations in the US on the life cycle greenhouse gas emissions of bioenery crops, in addition to perennial grasses such as switchgrass.
