The overall program goals are to: 1) Reduce uncertainty regarding the effects of rising atmospheric CO2 concentration on crops, pastures, invasive weeds, and plant diseases; and 2) Determine the role of agronomic management practices in the production of CO2 and other greenhouse gases (i.e., N2O and CH4), as well as the sequestration of atmospheric CO2 as organic C in soils. Specifically, my assignment focuses on: effects of atmospheric CO2 concentration on plant physiology, biomass allocation patterns, residue quality, the root system (distribution and function), trace gas emissions, soil carbon and nitrogen cycling, and related soil phenomena.
