Summary
Soil erosion on hilly land, Ninh Son district, Ninh Thuan province
Study in area of 31,791 ha in 5 communes in hilly and mountainous area in Ninh Thuan. Aim is to calculate certain constituents of the equation A = R.K.SL.C.P. (A: soil loss, R: rainfall erosivity, K: soil erodibility, SL: lope steepness and slope length, C: crop management, P: practice factor). Results showed that soil is vulnerable due to its physical characteristic or soil has high soil erodibility factor. Soil erosion was classified as medium soil erosion because of low rainfall but in some parts (high mountain or steep slope) have high potential erosion. Hence, farmers should pay attention in reforestation and upland cultivation with soil conservation measures to avoid high risk from soil erosion.
