The 'Phosphorus availability' fact sheet contains information to help growers make informed phosphorus application decisions.

Soils across cropping areas in Australia may be deficient in phosphorus (P) and require phosphorus fertiliser application to secure productivity.

This fact sheet covers measuring phosphorus availability; the difference between phosphorus fertilisers; application of phosphorus DGT in the paddock; phosphorus availability and root architecture; and the implications for phosphorus fertiliser management.
