The influence of cultivated measures on soil loss in watershed area
Farmer practice without soil conservation methods is a reason causing severely soil erosion on the watershed. Using appropriate cultivation approaches such as hedgerow by con tour lines reducing considerably soil loss in comparing with farmer practice about 38-43%. Mixed cropping, alley cropping intercropping, hedgerow by contour lines are good approaches: they are not only protected against soil erosion reducing 77-81%, but also improve soil moisture, increase crop yields eventually on the watershed. Intercrop between cassava and acacia mangium reduced soil erosion about 71-75%. Appropriate cultivation methods are not only maximum reducing soil erosion but also maintaining and improving soil fertility.
