Fertilizer application as a soil management practice improves crop quality and yield. Costs and environmental concerns often compel farmers to re-evaluate application rates so as to optimise the utilization of applied fertilizer and maximise crop production. Chemical perturbations as a result of human activity are particularly likely in agroecosystems because of the intensity of that activity, which include nutrient inputs intended to supplement native nutrient pools and to support greater biomass production and removal. An experiment was conducted to assess the long-term effect of nitrogenous based fertilizer on soil acidity. The trial consisted of three land used types, which are cultivated, fallow and forest respectively in the study area. Effects of ammoniacal N- fertilizer on cultivated land increase significantly (P<0.05) exchangeable acidityEA (1.5 cmol kg-1) with a decreases in cation exchange capacity(3.2cmol kg-1),(CEC). Percentage base saturation, decreases significantly (57%) in cultivated land with exchangeable Ca2+ and Mg2+respectively as compared to fallow land and forest land, under the application of ammoniacal Keywords: N N-fertilizer.
