A preferred composition incorporates a phosphate solubilising fungus, microorganism or reproductive material therefor, along with a nutrient capable of supporting same, into a phosphate material. Protein based nutrients, including fish based fertilising compositions have been found quite suitable. Variations include the introduction of free ammonia releasing microorganisms. Preferred embodiments of a composition are substantially dry, flowable, particles which may be coated with various agents. Also disclosed are methods for the preparation of such a composition, and the use of such compositions in increasing plant available phosphorus in soil.
