A field experiment was conducted at Alasulige village located in Sakleshpur taluk, Karnataka to study the influence of application of basic slag and lime along with different doses of chemical fertilizer on soil chemical properties using paddy as a test crop in an acidic soil. The experiment was laid out in RCBD pattern with ten treatments and three replicates. In general, the results revealed that the application of basic slag and lime at the rate of 2 t ha-1 increased the soil pH, available P2O5 content, decreased the DTPA extractable Fe and Mn content, exchangeable aluminium content and exchangeable acidity of soil. The study clearly indicated that in acidic soils, basic slag can be used as an alternative to lime for the amelioration of acidic soil and it can also be utilized as a nutrient source in acidic soil.
