To study the effect of sulphur levels and biofertilizer on solubility of rock phosphate


Author(s): SP Rakhunde, PP Kadu and PK Rathod

Abstract: The available and total P content increased in all the treatments with microbial incubation and elemental sulphur application. It can therefore be concluded that the release of phosphorus from rock phosphate can successfully be done by application elemental sulphur @ 60 kg ha-1 along with incubation of PSB and EM solution. The available and total phosphorus content of soil was increased with increase in the incubation period stage up to 90 days. The alkaline phosphatase activity was highest at the 30 day incubation stage. The phosphatase activity was decreased slightly at the 60 days stage and was observed to be lowest at the 90 days incubation stage. The higher phosphatase activity at 30 day and 60 day stage indicated higher microbial population at the initial stages of incubation of the microbial treatments.
