Thermodynamics predict that in calcareous soils where the equilibrium activity of solution orthophosphate (Pso) is controlled by any calcium-phosphate mineral, calcium oxalate (CaC2O4) precipitation will increase Pso by depressing Ca2+ ion activity in soil solution and enhancing dissolution of the P-controlling mineral. Plants and/or associated microflora capable of imparting effective levels of oxalic acid (H2C2O4) to soil solution, may significantly improve their phosphorus nutrition via this mechanism. In previous work, we presented evidence for calcium oxalate (CaC2O4) formation in the rhizosphere of vesicular-arbuscular mycorrhizal (VAM) western wheatgrass (Agropyron smithii Rydb.). Herein, we report on further...
