Abstract
The present invention relates to a method of enhancing growth conditions for plants by growing the plants in soil containing, in proximity to the plant roots, both a phosphorus source and at least two strains of the fungus Penicillium, particularly P. bilaiae, more particularly strains NRRL 50162 and NRRL 50169.
Claims19
A method of increasing the availability of phosphorus for plant uptake from soil, which method comprises introducing into the soil inoculums of at least two different strains of the fungus Penicillium selected from the group consisting of P. bilaiae, P. gaestrivorus, and combinations thereof.
A method of enhancing growth conditions of plants, which comprises growing the plants in soil containing, in proximity to the plant roots, both a phosphorus source and at least two strains identified by the deposit numbers NRRL 50169, NRRL 50162.
A composition for application to soil, which comprises:
- i) inoculums of at least two strains of the fungus Penicillium selected from the group consisting of P. bilaiae, P. gaestrivorus, and combinations thereof, and ii) a soil-compatible carrier for the fungus.
A plant seed having a coating comprising inoculums of at least two strains of the fungus Penicillium selected from the group consisting of P. bilaiae, P. gaestrivorus, and combinations thereof, and a solid soil-compatible carrier therefore.
