The lowest soil erosion on Molic Andosols could be due to their good aggregate stability and high permeability to water which make these soils resistanttowater erosion. Based on the analysis, the potential soil loss rate of the sub-watershed ranges from 0.89 to 5.29 ton/ha/year. Particularly in the northern provinces, which have been settled with sedentary agriculture for millennia, population density has caused major damage to the soils physical base, to its organic and chemical nutrients, and to the natural vegetation cover. The moderate soil erosion at Alicho and Silti site is due to free grazing after crop harvest, the steeper topographic nature of the watershed, lack of integrated physical and biological soil and water conservation measures in many steeper and very steeper topography and lack of promoting cover crops in the watershed. Lithosols are azonal soils with an incomplete solum and/or without clearly expressed morphological features. 9 0 obj Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. 0000001951 00000 n Oxford University Press, Oxford, pp 326341, Sutcliffe JP (1993) Economic assessment of land degradation in the Ethiopian highlands: a case study.

Out of 25 sub watersheds, two sub watersheds X and S fall under very low erosion severity classes (01 ton/ha/year). Based on the finding, the following points should be recommended, The Moderate and Low soil erosion severity areas should be managed through terracing, inter-cropping, contour farming, strip cropping, conservation tillage, mulching and biological stabilizers based on their slope range, soil type and land use type. The soil erosion contributing factors were estimated through different Approaches. The lowest soil erosion on Molic Andosols could be due to their good aggregate stability and high permeability to water which make these soils resistanttowater erosion.
