Plant growth-promoting rhizobacteria infused fertilizer
The present invention is a plant fertilizer product comprising at least one organic potassium source and at least one bacillus strain of rhizobacteria.
1. A composition comprising potassium acetate and at least one bacillus -based plant growth-promoting rhizobacteria and thiosulfate, wherein the composition is a fertilizer.
2. The composition of claim 1 wherein the fertilizer is storage stable for at least twelve months.
3. The composition of claim 1 wherein the bacillus -based plant growth-promoting rhizobacteria is added to deliver at least 5×10 3 cfu/mL of aqueous solution, wherein the cfu/mL reflects the viable concentration at the time of fertilizer composition preparation.
4. The fertilizer of claim 1 wherein the bacillus -based plant growth-promoting rhizobacteria are selected from the group consisting of bacillus amyloliquefasciens, bacillus licheniformis, bacillus marinus, bacillus megaterium, bacillus methylotrophicus, bacillus oleronius, bacillus pumilus, bacillus subtilis , or a combination thereof.
5. The composition of claim 1 further comprising soluble nitrogen, wherein the source of the soluble nitrogen is nitrate, ammonia, ammonium hydroxide, ammonium nitrate, ammonium thiosulfate, urea, ammonium salts, amino acids, or a combination thereof.
6. The composition of claim 1 further comprising soluble phosphate, wherein the source of the soluble phosphate is rock phosphate, sodium phosphate, potassium phosphate, phosphoric acid, monopotassium phosphate, dipotassium phosphate, tetrapotassium pyrophosphate, orthophosphate, ammonium phosphate, calcium phosphate, potassium phosphate generated by reaction of potassium hydroxide with phosphoric acid, or a combination thereof.
7. The composition of claim 1 further comprising soluble potassium from potassium formate, potassium citrate, potassium malate, potassium succinate, potassium propionate, organic sources of potassium, or a combination thereof.
8. The composition of claim 1 further comprising sulfur, zinc, boron, calcium, manganese, iron, copper, cobalt, sodium, magnesium, molybdenum, chloride, or a combination thereof.
9. The composition of claim 1 further comprising water.
10. The composition of claim 1 wherein the fertilizer is in granule, pellet, dust, powder, slurry, film, or liquid suspension form.
