Abstract

The present invention relates to a fertilizer comprising at least one microbe selected from the group consisting of Trichoderma viride (NRRL B-50520), Scopulariopsis brevicaulis (NRRL B-50521), Scopulariopsis brevicaulis (NRRL B-50522), and combinations thereof, and a substrate which is acted upon by the at least one microbe to release nitrogen. The invention also relates to a fertilizer comprising at least one microbe selected from a keratin degrading microorganism and a keratin substrate which is acted upon by the at least one microbe to release nitrogen. The invention further relates to a method for enhancing growth of plants with the fertilizer, and methods of making a fertilizer. The invention further relates to an isolated Trichoderma viride strain (NRRL B-50520) and two isolated Scopulariopsis brevicaulis strains (NRRL B-50521, NRRL B-50522).

Claims (47)

1. A fertilizer comprising:

at least one microbe selected from the group consisting of Trichoderma viride (NRRL B-50520), Scopulariopsis brevicaulis (NRRL B-50521), Scopulariopsis brevicaulis (NRRL B-50522), and combinations thereof and

a substrate which is acted upon by the at least one microbe to release nitrogen.

2. The fertilizer of claim 1 , wherein the substrate is a protein selected from the group consisting of feather, feather meal, and a derivative of urea.

3. The fertilizer of claim 1 further comprising:

a supplemental microbe in the form of a Trichoderma species.

4. The fertilizer of claim 1 further comprising:

a supplemental microbe selected from the group consisting of Piriformospora indica, a plant growth promoting rhizobacteria, mycorrhizal fungi, and combinations thereof.

5. The fertilizer of claim 1 , wherein the fertilizer is in granule, pellet, dust, powder, slurry, film, and/or liquid suspension form.

6. The fertilizer of claim 1 , wherein the fertilizer further comprises:

a nonproteinaceous binding agent selected from the group consisting of dextrans, starches, polyvinylchloride, and combinations thereof.

7. The fertilizer of claim 1 , wherein the fertilizer further comprises:

a soluble nitrogen source selected from the group consisting of nitrate, ammonia, ammonium salts, amino acids, urea, fish meal or extract, compost extract, kelp extract, shrimp extract, shellfish extract, and combinations thereof.

8. The fertilizer of claim 1 , wherein the fertilizer further comprises:

a source of phosphorus selected from the group consisting of rock phosphate, sodium phosphate, potassium phosphate, bone meal, and combinations thereof.

9. The fertilizer of claim 1 , wherein the fertilizer further comprises:

a source of potassium selected from the group consisting of potassium chloride, potassium phosphate, potassium sulfate, Jersey green sand, organic sources of potassium, and combinations thereof.

10. The fertilizer of claim 1 , wherein the fertilizer further comprises:

minor nutrients selected from the group consisting of salts, substances that contain iron, cobalt, manganese, magnesium, copper, calcium, boron, zinc, and combinations thereof.

11. The fertilizer of claim 1 , wherein the fertilizer further comprises:

a growing media.

12. The fertilizer of claim 1 , wherein the fertilizer further comprises:

a carrier selected from the group consisting of water, aqueous solutions, slurries, and powders.

13. The fertilizer of claim 1 , wherein the fertilizer further comprises:

an additive selected from the group consisting of insecticide, fungicide, nematicide, additional organic fertilizer, bioinsecticide, biofungicide, bionematicide, agricultural or horticultural adjuvants, stickers, spreaders, surfactants, dispersants, humectants, UV protectants, and mixtures thereof.

14. The fertilizer of claim 1 , wherein the fertilizer further comprises:

a source of organic carbon selected from the group consisting of compost and biochar.

15. A fertilizer comprising:

at least one microbe selected from the group of Trichoderma viride (NRRL B-50520), Scopulariopsis brevicaulis (NRRL B-50521), Scopulariopsis brevicaulis (NRRL B-505822), and combinations thereof and

a keratin substrate which is acted upon by the at least one microbe to release nitrogen.

16. The fertilizer of claim 15 further comprising:

at least one microbe selected from the group consisting of Streptomyces avermitilis, Streptomyces coelicolor, Streptomyces violaceoruber , and combinations thereof.

17. The fertilizer of claim 15 further comprising:

a supplemental microbe in the form of a Trichoderma species.

18. The fertilizer of claim 15 further comprising:

a supplemental microbe selected from the group consisting of Piriformospora indica, a plant growth promoting rhizobacteria, mycorrhizal fungi, and combinations thereof.

19. The fertilizer of claim 15 , wherein the fertilizer is in granule, pellet, dust, powder, slurry, film, and/or liquid suspension form.

20. The fertilizer of claim 15 , wherein the fertilizer is in the form of a liquid suspension comprising amino acids and ammonia.

21. A method of enhancing growth of plants, the method comprising:

providing a fertilizer comprising:

at least one microbe selected from the group consisting of Trichoderma viride (NRRL B-50520), Scopulariopsis brevicaulis (NRRL B-50521), Scopulariopsis brevicaulis (NRRL B-50522), and combinations thereof and

a substrate which is acted upon by the at least one microbe to release nitrogen; and

contacting the fertilizer with plants or plant seeds under conditions effective to enhance the growth of the plants or plant seeds compared to plants or plant seeds to which the fertilizer was not applied.

22. A method of making a fertilizer comprising amino acids and ammonia, the method comprising:

providing at least one microbe selected from the group consisting of Trichoderma viride (NRRL B-50520), Scopulariopsis brevicaulis (NRRL B-50521), Scopulariopsis brevicaulis (NRRL B-50522), and combinations thereof;

providing a substrate which is acted upon by the at least one microbe to release nitrogen; and

contacting the at least one microbe and the substrate under conditions effective to cause the at least one microbe to act on the substrate and produce a liquid suspension comprising amino acids and ammonia.
