Soil acidity is a series problem in south western part of Ethiopia due to high rain fall that aggravate the concentration of toxic elements like Al3+ and Fe2+. This study was conducted to evaluate the effects of lime with different fertilizer sources on soil chemical properties at Seka chekorsa area. Seven different treatments were applied with randomized complete block design along three replications. The study pointed out the response of soil pH (5.01) which was increased by 91.8% when compared to control plot (4.60), H+(0.25 cmol/kg), Al3+(0.19 cmol/kg), Exchangeable Acidity (0.44 cmol/kg), Available Potassium (1.96 Cmol/kg) and CEC (22.76 Cmol(+)/Kg) were attained significantly different result at (p<0.05) on CompL treated plot. However, OC (2.14%) and OM (3.69%) were attained the highest result on HCHNP and TN (0.1%) and Available K (2.00Cmol/kg) was significantly different at (p<0.05) on HCHNPL treated plot. The combined application of compost with lime was better than other combination including solely applied treatments to enhance different soil chemical properties in most of soil parameters. The integration of lime with organic and inorganic nutrient sources generally increased soil pH when compared with sole applied and control plot. Finally, the Integration of full recommended compost and Lime of agriculture could be promising alternative to amend acidic nitosol.
