The incubation study was conducted to know the extent of P solubility by microorganisms in fly ash added soil. This experiment was done by adding microbial culture ie, Pseudomonas straita and PGPR along with fly ash to soil. Significantly higher saloid-P and Ca-P fractions were recorded in the T9 treatment (Fly ash @ 80 t ha-1 + PGPR) which was followed by T7 treatment (Fly ash @ 20 t ha-1 + PGPR) as compared to control. Application of fly ash with Pseudomonas straita also increased saloid-P fractions in acid soil but its effectiveness is less than the inoculation of PGPR with fly ash. Higher values of Al-P, Fe-P, reductant-P, occluded-P, organic-P and total-P fractions were recorded in treatment that received only RDF and FYM (T1) as compared to the application of fly ash with P solubilizers. The T9(Fly ash @ 80 t ha-1 + PGPR) recorded lower value of Al-P, Fe-P, reductant-P, occluded-P, organic-P fractions and total-P in acid soil which was on par with T13 (Fly ash @ 40 t ha-1 + Pseudomonas straita).
