Soil bulk density for the world

Jan 19, 2011 (Last modified Apr 18, 2011)
Description:
This file contains soil data for 3 depths (0-0.5 meters, 0.5-1.5 meters, and greater than 1.5 meters) for percent sand, clay, and rockiness for the entire globe at a half degree grid resolution. A single bulk density value and mineral depth are also provided for each gridcell. Bulk density values came from the the International Geosphere Biosphere Programme (IGBP). Mineral depth, clay, sand, and rockiness values came from the International Satellite Land Surface Climatology Project (ISLSCP).
