                                Technical Abstract: The mission of the Labex - ARS/Embrapa Cooperation Program is to promote opportunities for institutional cooperation in agricultural research.  A two-year project was initiated in June 2002 with the Environmental Quality Laboratory to examine the dynamics of soil microbial biomass and metabolic quotient within agricultural landscapes, to assess measurement techniques for greenhouse gas (CO2, N2O, CH4) emissions, and to develop soil management strategies to sequester carbon and decrease greenhouse gas emissions.  Despite some divergence in climate policy between the U.S. and Brazil, there is convergence on many research issues related to global change.  Embrapa and EQL have established the following activities with additional collaborators:  (1) Cesium-137 used as a tracer for soil movement due to agricultural practices in Brazilian landscapes (USDA-ARS/Hydrology and Remote Sensing Laboratory); (2) development of Spectral libraries based on NIR/MIR (near and mid infrared) for the Brazilian soil collection (USDA-ARS/Animal Manure and By-products Laboratory); and 3) establishment of cooperation in animal waste management research (USDA-ARS/Coastal Plain Soil, Water and Plant Conservation Research Unit).  Other research opportunities include examining no-tillage management and soil carbon characterization, as well as a soil carbon dating and paleoclimate project in Brazil (USDA-ARS/Soil-Plant-Nutrient Research Unit).  A workshop is planned on "Opportunities for Scientific Cooperation between Brazil and the United States" and will be held at the Woodrow Wilson Center in Washington, DC.
