GLOBAL DATA SET OF DERIVED SOIL PROPERTIES, 0.5-DEGREE GRID (ISRIC-WISE)
Global Data Set of Derived Soil Properties, 0.5-Degree Grid (ISRIC-WISE)
The World Inventory of Soil Emission Potentials (WISE) database currently contains data for over 4300 soil profiles collected mostly between 1950 and 1995. This database has been used to generate a series of uniform data sets of derived soil properties for each of the 106 soil units considered in the Soil Map of the World (FAO-UNESCO, 1974). These data sets were then linked to a 1/2 degree longitude by 1/2 degree latitude version of the edited and digital Soil Map of the World (FAO, 1995) to generate GIS raster image files for the following variables:
- total available water capacity (mm water per 1 m soil depth),
- soil organic carbon density (kg C/m**2 for 0-30cm depth range),
- soil organic carbon density (kg C/m**2 for 0-100cm depth range),
- soil carbonate carbon density (kg C/m**2 for 0-100cm depth range),
- soil pH (0-30 cm depth range), and
- soil pH (30-100 cm depth range).
