Effect of immobilized phosphate solubilizing bacteria on wheat growth and phosphate uptake

A study was performed to investigate the efficiency of rhizobacteria on solubilization of rock phosphate and their assimilation by wheat plants in quartz sand potted experiments. Two phosphate solubilizing bacteria, P.fluorescens and Serratia sp. were encapsulated in sodium alginate and potato starc...
