Figure 1.
Schematic representation of the importance of microorganisms to P availability in soil. Microorganisms and their interactions in soil play a critical role in mediating the distribution of P between the available pool in soil solution and the total soil P through solubilization and mineralization reactions, and through immobilization of P into microbial biomass and/or formation of sparingly available forms of inorganic and organic soil P.

Figure 2.
Key biological processes associated with microbially mediated plant growth promotion through mechanisms that may either directly or indirectly increase the availability of soil P or enhance a plant’s capacity to acquire P from soil.
Figure 3.
Figure 3.
Microbial biomass and depletion of soil P in the rhizosphere of perennial ryegrass (white circles) and radiata pine (black triangles), as compared to control (unplanted; black circles) soil. Shown are: microbial biomass C (A) and NaOH-extractable inorganic P (B) and organic P (C) following a sequential extraction procedure. Plants were grown in a rhizobox system using an Orthic brown soil (Dystrochrept) from Hurunui in New Zealand (pH 5.6; soil-water extract) and analyzed as reported by Chen et al. (2002). For each panel the error bar (lsd) shows lsd (P = 0.05).
