Project Number: 5402-11000-006-00
Project Type: Appropriated

Start Date: Feb 26, 2001
End Date: Mar 31, 2005

Objective:
Research is to be directed to understanding basic processes of soil carbon and nitrogen cycles, which will allow the results to be used to develop solutions to a broad spectrum of problems.

Approach:
Field and laboratory studies will be used to: 1) determine regional effects of climate and management on soil organic-C pools; 2) estimate of soil C storage in historic grasslands; 3) determine impact of elevated CO2 on the shortgrass-prairie; 4) determine relative contribution of microbial, physical and chemical processes of N loss and soil N conservation; 5) characterize magnitude and mechanisms of C and N emission pulses that follow system pertubation; and, 6) develop/validate process-basedsimulation models that permit regional scale prediction of changes in soil C, trace gas fluxes and N retention.
