ABSTRACT
The phosphorus incubation was conducted for 0, 3, 7, 14, 28, 56 and 90 days in a Completely Randomized Design with three fertilizer treatments Triple Super Phosphate (TSP) Phosphate Rock (PR) and Bone Material (BM) applied @ 40 and 80 mg kg-1 in an alkaline calcareous soil. Generally maximum phosphorus was available at d0(day zero) and decreased with increase in incubation time. At day 0, the mean available phosphorus was 42.5% in TSP treatment followed by 5.5 and 4.8% P solubility in phosphate rock and bone material treatment. At day 90, only 10.12% phosphorus was available in TSP treatment followed by 0.0% phosphorus availability in PR and BM treatments. The minimum TSP sorption was observed at d0 and increased with the increase in incubation time. The results indicated a rapid initial sorption of TSP and the decrease in the sorption intensity with time. The sorption saturation (maximum sorption) was attained at 14 days incubation of 80 mg P kg-1 as TSP. The increase in incubation time did not further affect P fixation of upper TSP level however the lower level (40 mg P kg-1) decreased constantly up to 90 days incubation.
