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.
