Soil Acidity affects soil ecology and plant growth. It influences soil productivity by elemental toxicity, reducing nutrient solubility and availability as well as microbial activity. Moreover, deficiency of elements (Ca, Mg, Mo), Phosphorous - fixation, incidence of plant disease (fungal) and poor bacterial growth are also observed. Activities such as mismanagement of agricultural practice, depletion of base cations, weathering of acidic parent material and organic matter dissociation boost soil acidification processes. However, the magnitude and rate of soil acidification...

Ethiopia is endowed with abundant natural resources and biodiversity. Yet the sustainability of these resources is under threat. The initial alarming projections of environmental scarcity, inadequate supplies of minerals to sustain industrialization and agricultural production are too limited to meet the needs of a growing population.Environmental services are inadequate to disperse increasing quantities of waste and have given way over time to a broader view of growing insecurity. Resource scarcity poses new challenges, it also encourages the development of technologies that allow for the...
