). Consequently, soil fertility and its edaphic microbiota’s capacity to carry out biogeochemical cycles are decreasing (Dawwam et al. 2013; Sivasakthi et al. 2014).
Plant roots uptake inorganic P is as orthophosphate through non-symbiotic physiological mechanisms; however, through symbiosis with “plant-growth promoting Rhizobacteria” (PGPR), it facilitates, even more, their absorption (Richardson 2001; Richardson et al. 2009). PGPR solubilize P precipitated in the soil by synthesis and secretion of organic
