Abstract
The relative efficiency of different forms of P in relation to their time of application for growing rice on different soil types has been studied by using /sup 32/P tagged mono-, di-, and tri-calcium phosphate, ammonium nitrate phosphate containing all the P in the citrate-soluble form and potassium meta-phosphate. P-deficient acid laterite soil from Burdwan, red loam soil from Peramanpur and calcareous black soil from Hyderabad were used in the study. The different P forms were found to be compatible in the acid, red and laterite soils when the phosphorus forms were primed to moist acid soils 2 weeks prior to flooding. On application at flooding, fertilizers containing citrate-soluble phosphate were found to be less effective as compared to those containing water-soluble phosphate. In the calcareous black soil, however, the fertilizers, containing insoluble or citrate-soluble phosphates were not as efficient as the water-soluble forms, possibly because of lack of dissolution process. Potassium meta-phosphate was found to be effective in all the soil types whether applied at flooding or primed to the moist soil.
