Phospho compost application is important with respect to
soil fertility and plant nutrition. Therefore, the objective was to evaluate
the influence of phospho compost application on P availability and uptake by
maize in red soil. The phosphorus
applied in the form of phospho compost, as compare to rock phosphate and super
phosphate at a rate of 50 and 100 mg P2O5 Kg-1 soil. The application was done as spot and mix
application. Results indicate that, spot application of 100 mg P2O5 kg-1 soil as phospho
compost (b) registered significantly higher P uptake (2.1 and 5.31 mg·pot-1)
and available soil P (19.1 and 21.0 mg·kg-1) as compare to Rock
Phosphate alone (0.60 and 0.97 mg·pot-1) and (5.6 and
6.0 mg·kg-1) at 30 and
60 day after sowing, respectively. The probable chelating effect from phospho
composting increased the phosphorus use
