Organic acids production by rhizosphere microorganisms isolated from a Typic Melanudands and its effects on the inorganic phosphates solubilization
It has been established that organic acid secretion by rhizosphere microorganisms is one of the mechanisms to solubilize the phosphorus (P) attached to insoluble mineral compounds in soil. This action is an important biotechnological alternative, especially in those soils where high fixation of this...
