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.
