Effect of different sources of phosphatic fertilizers on P availability and its transformation in submerged rice soil



Effect of different sources of phosphatic fertilizers on P availability and its transformation in submerged rice soil



Mysore Journal of Agricultural Sciences 39(2): 234-239



This study was conducted to determine the effect of bone meal on nutrient availability and transport in a submerged rice soil (Inceptisol). Results showed an increase in crop yield, Olsen's P and all other estimated P fractions. The effect was comparable with the combined addition of organic and inorganic P sources to supply the recommended P in equal proportion. Among the various P fractions, 50-60% of the applied P was converted into Ca-P, which was followed by the Fe-P, Al-P and saloid-P.
