The role of integrated watershed management on soil-health in northern Ethiopia
Integrated watershed management (IWSM) technologies have been implemented around the world, including in the northern highlands of Ethiopia during the last few decades. However, their role in improving soil-health along different geological formations is not well studied. This study was, thus, aimed...

| description | Integrated watershed management (IWSM) technologies have been implemented around the world, including in the northern highlands of Ethiopia during the last few decades. However, their role in improving soil-health along different geological formations is not well studied. This study was, thus, aimed at quantifying the impact of IWSM on soil-health under dolerite and sandstone geological formations. Twelve soil samples were taken from two watersheds with IWSM and another 12 soil samples from two watersheds without IWSM at 30 cm soil depth. Physical, chemical, and biological properties of these soil samples were then analysed in a laboratory. Soil moisture content, Soil organic matter, total nitrogen, available phosphorus (Pav) and arbuscular mycorrhizal fungi spore density of soils were significantly high in watersheds with IWSM as compared to watersheds without IWSM. Although insignificant, total porosity, cation exchange capacity, Exchangeable bases and micronutrients also had higher mean value on watersheds with IWSM practices than watersheds without. Thus, this study reviled that an introduction of these IWSM practices has a positive impact in improving soil-health. Moreover, IWSM practices implemented on dolerite geological formation showed a higher impact on soil-health as compared to management practices implemented on sandstone geological formation. |
