Abstract:
The experiment was carried out to study the effect of microbial culture on phosphorus release in fly ash amended soil. The four levels of fly ash 10, 20, 40, and 80 t ha-1 with and without PGPR and P. straita were tried in a completely randomized design (CRD) with 13 treatments. Results of laboratory incubation study revealed that higher levels of fly ash with and without PGPR and P. straita increased soil pH up to 90 DAI (soil pH was increased from acidic to neutral) except 10, 20, and 30 DAI which showed non-significant. Higher values of available phosphorus were recorded in the treatments that received higher levels of fly ash with PGPR and PSB treatments as compared to the control. However, a significantly higher value of available phosphorus was observed in the treatments T9 which received Fly ash @ 80 t ha-1 + PGPR which found on par with T13 (Fly ash 80 t ha-1 + P. straita) and significantly lower available phosphorus was observed in control where fly ash and P solubilizers were not applied. Under incubation study, the maximum phosphorus fixation capacity of acid soil was observed in the treatment T1 and lower P fixation capacity was recorded due to the application of a higher dose of fly ash 80 t ha -1 with PGPR.
