Soil Acidity Formation and its Amelioration Methods in Ethiopia: A Review

Abstract

Soil acidification is one of the problems of chemical soil degradation affecting soil productivity in the world. This paper attempts to explain the concept of soil acidification, the causes of soil acidification and the methods to remedy it. Farmers need simple and sustainable techniques to improve acidic soils and increase yields of their chosen crops. Recommendations for reclamation of acid soils need to be adapted to new developments, such as liming, use of acid-tolerant crop varieties, integrated soil fertility management, and application of organic fertilizers. This review addresses the causes and management mechanisms of soil acidification and the resulting effects on soil fertility and crop yield. It also provides important information on management options to address soil acidity and improve overall soil fertility, as well as other organic amendments that can be applied to bring soil acidity to the desired pH and improve soil quality and health. Integrated management of acidic soils increases yield stability and maximizes nutrient use efficiency.
