CLAIMS

What is claimed:

1 . A composition for enhancing the rate at which organic soil phosphorus is converted to orthophosphate comprising two or more isolated bacterial strains selected from the group identified in Table 2.1 , and a carrier.

2. The composition of claim 1 , wherein the two or more bacteria strains includes a sequence of greater than 200 nucleotdes that has 97% identity to one of SEQ ID NOs: 1 -4.

3. The composition of any of claims 1 to 2, wherein bacteria is selected from the group consisting essentially of Enterobacter cloacae, Citrobacter fruendii, Comamonas testosteroni, Psuedomonas putida, and combinations thereof.

4. The composition of any of claims 1 to 3 comprising a Phosphorus Mobilizing Consortia and/or a Mineralizing Consortia, wherein the two or more bacteria are selected from bacteria with NRRL Accession numbers NRRL B-67136, NRRL B-67137, NRRL B-67138, and NRRL B-67139 .

5. The composition of any of claims 1 to 4, wherein the carrier comprises one or more compounds extracted from alfalfa.

6. The composition of any of claims 1 to 5 wherein said composition is a liquid.

7. The composition of any of claims 1 to 6 wherein said composition is concentrated to remove water.

8. The composition of claim 7 wherein said composition is diluted with water before use.

9. A method for enhancing the rate at which organic soil phosphorus is converted to orthophosphate comprising:

contacting two or more bacterial species selected from the group identified in

Table 2.1 , with a soil.

10. The method of claim 9 wherein said two or more bacterial species each comprises an rRNA 16S sequence of greater than about 200 nucleotides with at least 97% identity to one of SEQ ID NOs: 1 -4.

11 . The method of any of claims 9 to 10, wherein the soil comprises a seed or plant.

12. The method of any of claims 9 to 1 1 wherein the two or more bacteria are selected from bacteria with NRRL Accession numbers NRRL B-67136, NRRL B-67137, NRRL B-67138, and NRRL B-67139.

13. The method of any of claims 9 to 12 further comprising the step of allowing a seed or plant within the soil to grow.

14. The method of any of claims 9 to 13 wherein a seed or plant is added to the soil after contacting the soil with the two or more bacteria.

15. The method of any of claims 9 to 14 wherein the soil is contacted with by spraying the soil with the two or more bacteria.

16. The method of any of claims 9 to 15 wherein the two or more bacteria are comprised in a powder or granulated composition that is applied to the soil.

17. The method of any of claims 9 to 16 wherein the two or more bacteria are mixed with water before contacting the soil.

18. A method of increasing the growth rate of a plant comprising;

contacting a soil with two or more bacterial species selected from the group with NRRL Accession numbers NRRL B-67136, NRRL B-67137, NRRL B-67138, and NRRL B-67139;

allowing the two or more bacterial species to solubilize one or more phosphorous compounds;

allowing the plant to take up the solubilized phosphorous, thereby increasing the growth rate of the plant.

19. The method of claim 18, the soil is contacted with all four bacterial species.

20. The method of any of claims 18 to 19, wherein the height, weight, color, or yield of the plant is measured to determine growth.

21 . The method of any of claims 18 to 20, wherein the growth of the plant is at least 2% greater than a similar plant grown in soil that has not been contacted by the two or more bacterial species.
