National Program 212: Soil and Air
GRACEnet Introduction
headline bar

GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) is a research program that has been initiated by the USDA-ARS. The primary objective of GRACEnet is to identify and further develop agricultural practices that will enhance carbon sequestration in soils, promote sustainability and provide a sound scientific basis for carbon credits and trading programs. This program will generate information concerning carbon storage in agricultural systems that is needed by producers, program managers and policy makers. GRACEnet also addresses the other greenhouse gases, nitrous oxide and methane that may be emitted by agricultural practices. Agricultural lands to be studied by GRACEnet scientists include both grazing lands (range and pasture) and crop lands (irrigated and dryland). Coordinated multi-location field studies will follow standardized protocols to compare net GHG emissions (carbon dioxide, nitrous oxide, methane), carbon (C) sequestration, and broad environmental benefits under different management systems that:

  1. typify existing production practices,
  2. maximize C sequestration,
  3. minimize net GHG emissions,
  4. meet sustainable production and broad environmental benefit goals (including C sequestration, net GHG emissions, water, air and soil quality, etc.).

ARS Portal to GRACEnet, REAP and Stewards multi-location team data

You will need to have Microsoft Silverlight installed for the portal to launch properly.

This application is an ongoing effort of the USDA Agricultural Research Service (ARS) to increase the availability of research data to the broader research community.  The data contained within this application represents complex data relationships amongst hundreds of scientific measurements. See Del Grosso et al 2013 for background information.
