I need soil erodibility (K) factor values assigned to soil type according FAO soil classification for the evaluation of soil loss using RUSLE. Thank You.
I think not. I refer both to FAO, and it's continuation - WRB (last edition 2014). Some soil types (WRB Soil Reference Groups) may occur in different landscape positions, for example Cambisols, Regosols, Luvisols etc. and may have different texture (loams, silts etc). Consequently their erodibility factor depends both on terrain attributes (slope) and soil texture.
Some soil occur mainly in plain landscapes (Fluvisols, probably also many Vertisols) so we can assign them rather small susceptibility to erosion. At least water erosion, because some Fluvisols with great content of silt might be susceptible to wind erosion.
Best regards.
Dear Jeevan Kumar Van and Michał Stępień:
I agree with those reported by Stępień about the distribution of different soil types in a particular landscape, just point out that there are many factors that may favor or stop soil erosion, it is necessary to know very well the climate of the region, topography and geomorphology of the area dynamics, geology and vegetation. Besides having clear texture of the soil, the type of clay and organic matter content, as these influence their retention, lighter materials move faster or are put in suspension by water, but if there vegetation is It is slowed.
One element that forms hard layers such as calcium (Calcium hydrogen carbonate Ca (HCO3) 2 or the silicon (SiO2) can prevent total soil erosion. On the other hand, If the soil is on limestone material must remember erosion Vertical produced by the dissolution of limestone forming small or large holes, but still cracks penetrating the soil material deeper.
It is also necessary to regionalize, taking into account the dynamic geomorphology of the area under study.
what of according to colour.
for example silandic andosols,albic lubisols,
There is any data base to extract the RUSLE factor K from soil classification?
