Service Description: The Rapid Carbon Assessment (RaCA) was initiated by the USDA-NRCS Soil Science Division in 2010 with the following objectives: To develop statistically reliable quantitative estimates of amounts and distribution of carbon stocks for U.S. soils under various land covers and to the extent possible, differing agricultural management. To provide data to support model simulations of soil carbon change related to land use change, agricultural management, conservation practices, and climate change. To provide a scientifically and statistically defensible inventory of soil carbon stocks for the U.S. To accomplish these objectives, 144,833 samples were collected from the upper 1 meter of 32,084 soil profiles at 6,017 randomly selected locations for measurement of organic and inorganic carbon by visible and near infrared (VNIR) spectroscopy and bulk density by traditional methods. NRI sites were used as the basis for random selection of sample sites stratified by soil group within RaCA Region and land use/land cover (LULC) within soil group. Soil morphology and landscape characteristics were described at each site and limited vegetation and agricultural management information was collected from each location. Sample collection and analysis involved more than 300 soil scientists and assistance from 24 universities.
