Soil Organic Carbon (STATSGO2) 0-100cm

SOC gC/m2 US General Soil Map or STATSGO2 source

Soil Organic Carbon was computed for a 100cm soil depth (units are g C per square meter) using the methods previously published (Bliss, Waltman, and Petersen, 1995 Preparing a Soil Carbon Inventory of the U.S. Using GIS In. Soils and Global Change, Advances in Soil Science, CRC-Lewis Publishers Boca Raton., pp. 275-295; Bliss, Waltman, and Ping. 2002. Eos Transactions American Geophysical Unit, 83, 47, F0743) using a 12/30/2009 snapshot of the Digital General Soil Map of the United States for the Conterminous U.S. (Rapic Carbon Assessment or RaCA Project). The U.S. General Soil Map consists of general soil association units. It was developed by the National Cooperative Soil Survey in 2006 and supersedes the State Soil Geographic (STATSGO) dataset published in 1994. It consists of a broad-based inventory of soils and non-soil areas that occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped.
