Effect of fly ash combination with and without organic fertilizer on physico-chemical properties of vertisol

Field experiment were conducted in farmer field around National Thermal Power Corporation (NTPC) Sipat, Bilaspur (C.G.) during kharif season 2013 to evaluate different doses of fly ash(20,40,60 t ha⁻¹) combination with and without organic fertilizer on physico-chemical properties of soil. The results generated showed that fly ash integrated with recommended fertilizers and FYM imprinted significant positive effect on major nutrient availability in soil. Higher soil organic carbon content of soil recorded in fly ash applied with organic fertilizer. Application of increasing doses fly ash with and without FYM was found to increase water holding capacity and the highest recorded under application of 75% GRD + 60 t ha⁻¹ fly ash + 5 t FYM ha⁻¹ and tended to marginal decrease bulk density and particle density of soil and there effect was non significant.
