Soil Acidity Effect and Management in Different Land Uses: Soil Acidity Effects on Productivity and Environment

The function of soil is generally threatened by the increasing and often conflicting demands of a constantly growing human population and its activities, as well as by land use and climate change. This leads to a number of physical, chemical, and biological degradation processes that affect the sustainable functioning of soils (EEA, 1999). Soil acidity is a serious constraint for crop production in many regions of the world, Ethiopia included. So liming soil acidity can increase the productivity of soil in sustainable way.
