A field experiment conducted to evaluate the effect of soil amendments on the chemical properties of vertisol revealed that application of organics viz., poultry manure, farm yard manure and inorganics like furance slag and lime sludge improved the organic carbon, available nitrogen and phosphorus status. The total cation exchange capacity of soil was positively correlated with organic carbon content. The exchangeable calcium and magnesium status were improved by time sludge and magnesite treatments, respectively. Application of poultry manure, farm yard manure and lime sludge significantly improved the yield of finger millet (CO 10). Organic amendments were superior to inorganics in improving the chemical properties of soil and yield of finger millet.
