Vol. 2 No. 2 (2019): Effect of Applied Lime and Mineral Phosphorus Fertilizer on Phosphorus Transformation in Acid Soils of West Wollega, Ethiopia

ABSTRACT
Prevalent occurrence of P deficiency in strongly acid soils is one of the major problems limiting crop production in high rainfall regions of Ethiopia where Phosphorus (P) fixation, nutrient leaching and soils erosion are common. This work investigated effect of liming and applied mineral P on the P transformation of acid soils of West Wollega, Ethiopia. To study the P transformations, P fractionation was carried out to determine distributions of P in the various P pools. The soils were categorized as strongly acidic in which the pH (H2O) values varied between 4.35 and 4.82.
