Abstract:
County level simulations will be carried out for the state of Texas to examine C dynamics and GHG emissions in selected conventional crops in the period of 1982 - 2012. The focus of regional simulations for all Texas counties and the state as a whole during this period will include: (1) yields of major crops (grain corn, upland cotton, winter wheat, grain sorghum, and hay) under conventional field management practices , (2) SOC levels in respective cropping systems, and (3) net GHG budget for each cropping system, including crop/soil system CO2 flux, direct and indirect N2O emissions, CH4 uptake, and the fuel CO2 costs of farm machinery operation and production of N fertilizer input.
