Land Degrad Dev 15:499512, Merritt WS, Letcher RA, Jakeman AJ (2003) A review of erosion and sediment transport models. 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. The soils of Ethiopia can be classified into five principal types.

The annual average soil loss rate was estimated for effective watershed management intervention. household uses due to increasing population ultimately lead to severe soil Therefore, the soil erosion could be reduced if the current land use land cover scenario is considered. In addition, the gelada monkey is under threat. Without their hospitality and collaborative approach this work would have never seen the light. endobj As the slope steepness increases from level slope (<1%) to very steep slope (>45%), soil erosion increases (Fig. The mean annual soil loss rate was analyzed based on the sub-watersheds, soil types, land uses, slopes and woreda basis. examining different topographic and anthropogenic factors for the planning and However, many authors estimated the rate of soil erosion in different parts of the regions; their result could spatially vary. This paper tries to put together soil acidity concept, causes, extent and management practices. Podzols having a thin iron pan in or over the spodic B horizon, Other Podzols showing hydromorphic properties within 50 cm of the surface, Other Podzols having a B horizon in which a subhorizon contains dispersed organic matter and lacks sufficient free iron to turn redder on ignition, Other Podzols in which the ratio of percentage of free iron to percentage of carbon is 6 or more in all subhorizons of the B horizon, Other Podzols lacking or having only a thin (2 cm or less) and discontinuous albic E horizon; lacking a subhorizon within the B horizon which is visibly more enriched with carbon. It is also one of the biggest threats in Ethiopian highland which threatens agricultural productivity.
