With recognition that increased consumption of N and P fertilisers and the augmentation in soil Olsen-P levels is unsustainable, there is impetus to identify micro-organisms capable of delivering these elements to plants. Phosphate solubilising bacteria present in the rhizosphere or in nodules have the capacity to convert immobilized soil P into plant available P, and promote plant growth. The potential to identify strains with dual activity of N-fixation and P-solubilisation makes them a promising group for research efforts.en© The Authors.P fertilisersN fertilisersRhizobiumPseudomonasBurkholderiaConference Contribution - unpublishedANZSRC::079902 Fertilisers and Agrochemicals (incl.
