Question

Role of microorganism to increasing phosphorus availability

Answer 1

The concept of microbial enhancement of P availability to plants is not new. Gerretsen (1948)showed that pure cultures of soil bacteria could increase the P nutrition of plants under controlled conditions through solubilization of precipitated forms of calcium (Ca) phosphates. Since this study, many examples of microbially mediated P mobilization and characterization of different microorganisms have been reported (for review, see Richardson, 2001; Gyaneshwar et al., 2002; Khan et al., 2007, 2010; Harvey et al., 2009; Richardson et al., 2009a; Zaidi et al., 2009). However, despite considerable promise microbial products for P mobilization have not had major application to broad-acre farming systems. An exception to this is the commercialization of fungal-based inoculants in North America and more recently in Australia and Europe.
