The Erodibility Of Some Ghanaian Soils In Relation To Their Physical And Chemical Properties.

ABSTRACT

The erodibility of soils from six different rainfall

erosivity areas in Ghana were investigated. The soils were

sampled and packed into wooden boxes maintained at 9%

slope. Soil erosion was measured by applying simulated

rainfall storms over the soil samples. The erodibility

factor K for each soil type was calculated from USLE,

K=A/EI30LSCP. The results showed a variability in

erodibility factor values which ranged from 0.36 to 0.62.

The physical and chemical properties of the soils were also

measured and correlated with K values using regression

techniques. The statistical analysis showed that the most

important properties which related and predicted the K

values for the soils studied were, permeability , pH and

percentages of fine sand, clay and very fine sand .
