Indian soils are deficient in nitro-gen and phosphorus and hence a good crop response may be expected for these nutrients. The utilisation of nitrogen and correspondingly the uptake pattern of the seme in crops will be in proportion to the uptake of the phosphorus from the soil as these two go together always (Menkinar 1956. Stefan and Boti. 1960). The role of phosphobacter in augmenting P uptake in plants has been recognised.
