Soil Organic Carbon Map

Soil Organic Carbon Map

  • Key Words: soil carbon, organic carbon, soil carbon map
  • About the Map: The Soil Organic Carbon map is based on a reclassification of the FAO-UNESCO Soil Map of the World combined with a soil climate map. The soil organic carbon map shows the distribution of the soil organic carbon to 1 meter depth.
  • Possible Uses of the Map: Useful for teachers and students who are interested in the global distribution of soil carbon. Climate change modelers may be able to use the data for small scale analysis.
Data
  • Sources: FAO-UNESCO, Soil Map of the World, digitized by ESRI. Soil climate map, USDA-NRCS, Soil Science Division, World Soil Resources, Washington D.C. Soil Pedon database, USDA-NRCS National Soil Survey Center, Lincoln, NE.
  • Data Aggregation and Reliability: The soil carbon map data is rasterized on a 2 minute grid cell.
  • Data Definitions: Six classes of soil organic carbon volume ranges. Kg/m/m2
  • Data Disclaimer: Country boundaries are not authoritative.
