The data set is hwsd soil texture data set of Shule River Basin
The main fields of soil attribute table include:
SU_ Sym90 (soil name in fao90 soil classification system)
SU_ Sym85 (fao85 classification)
T_ Texture (top soil texture)
DRAINAGE(19.5)；
Roots: string (depth classification of obstacles at the bottom of soil)
SWR: string (soil water content characteristics)
ADD_ Prop: real (specific soil type related to agricultural use in soil unit)
<>T_ Grave: real (volume percentage of gravel); t_ Sand: real (sand content)
T_ SIL T: real (silt content)
T_ Clay: real (clay content)
T_ USDA_ Tex: real (USDA soil texture classification)
T_ REF_ Bulk: real (soil bulk density)
T_ OC: real (organic carbon content)
T_ PH_ H2O: real (PH)
T_ CEC_ Clay: real (cation exchange capacity of clay soil)
T_ CEC_ Soil: real
T_ BS: real (basic saturation)
T_ TEB: real (exchangeable base)
T_ Carbonate content (CA3: real)
T_ CaSO4: real (sulfate content)
T_ ESP: real (exchangeable sodium salt)
T_ ECE: real (conductivity).
≪ P where t_ The attribute field at the beginning represents the upper soil attribute (0-30cm), with S_ The beginning attribute field represents the subsoil attribute (30-100cm) (FAO 2009).The data can provide model input parameters for earth system modelers, and agricultural perspective can be used to study eco agricultural zoning, food security and climate change.
The data comes from the world soil database (hwsd) built by FAO and IIASA in Vienna, which was released on March 26, 2009
The main soil classification system used is fao-90
