Abstract
The distribution of forms of phosphorus in an acid ferruginous soil after application of superphosphate is studied. Of the P2O5 added as superphosphate, 88% was retained by the soil 3 days after application. Most of the superphosphate added was converted into sesquioxide‐bound P2O5 and adsorbed P2O5. Liming the soil increased the Truog's sulphuric acid‐soluble P2O5 by about 10%. Adsorbed P2O5 (hydroxyl‐replaceable P2O5) rather than Truog's soluble P2O5 appeared to be utilised by the jute crop.Keywords
