Abstract/Contents:"Pot trials using phosphated-goethite (bridging complex) as the source of P for ryegrass were established. No P was readily available to ryegrass until the surface was > 40% covered with phosphate ions. Availability increased as the P level in solution increased up to 2 µM. Maximum availability was attained when the initial concentration of P in solution was 2 µM which occurred at about 75% coverage on goethite. Mycorrhiza increased the availability of phosphate at a level of about 0.5-2 µM P (60-70% coverage of the goethite surface). Laboratory experiments showed that citrate ions were particularly effective in displacing P from goethite and the Olsen reagent was a good predictor of P availability to ryegrass."
