Anti-caking fertilizer compositions
A particulate fertilizer coating composition or a coated fertilizer containing a solid acidic particulate material and a solid basic particulate material. The coating composition and coated fertilizer are each stable, chemical compatible with other fertilizers, and/or are abrasion resistant.
1. A fertilizer composition comprising a urea and/or phosphate containing fertilizer particle having at least a portion of its surface coated with a bacteria and with a nutrient, wherein the nutrient comprises at least one of an amino acid, a nitrogen source, a phosphorous source, or a sulfur source.
2. The fertilizer composition of claim 1 , wherein the bacteria and the nutrient are comprised in two different layers.
3. The fertilizer composition of claim 2 , wherein the fertilizer particle has at least a portion of its surface coated with a micronutrient.
4. The fertilizer composition of claim 3 , wherein the micronutrient is comprised at least in part in a layer different than the layer comprising the bacteria and the layer comprising the nutrient.
5. The fertilizer composition of claim 4 , wherein a first coating layer comprises the bacteria, a second coating layer comprises the nutrient, and a third coating layer comprises the micronutrient.
6. The fertilizer composition of claim 2 , wherein at least a portion of the bacteria is comprised in a layer between the fertilizer particle and a layer comprising the nutrient.
7. The fertilizer composition of claim 1 , wherein the fertilizer particle has at least a portion of its surface coated with a micronutrient.
8. The fertilizer composition of claim 7 , wherein the micronutrient comprises a metal oxide.
9. The fertilizer composition of claim 8 , wherein the metal oxide is MgO, ZnO, CuO, or blends thereof.
10. The fertilizer composition of claim 8 , wherein the micronutrient comprises MgO.
11. The fertilizer composition of claim 7 , wherein the micronutrient is comprised in a solid particulate material.
12. The fertilizer composition of claim 7 , wherein at least two of the bacteria, the nutrient, and the micronutrient are comprised in a single layer.
13. The fertilizer composition of claim 1 , wherein the nutrient comprises at least two of an amino acid, a nitrogen source, a phosphorous source, or a sulfur source.
14. The fertilizer composition of claim 1 , wherein the bacteria and/or nutrient is comprised in a particulate material.
15. The fertilizer composition of claim 1 , wherein the fertilizer particle comprises urea.
16. The fertilizer composition of claim 1 , wherein the fertilizer particle comprises a phosphate.
17. The fertilizer composition of claim 1 , wherein the bacteria and the nutrient are comprised in a single layer.
18. The fertilizer composition of claim 1 , wherein the composition is a blended fertilizer composition comprising a plurality of the coated fertilizer particles and a plurality of uncoated fertilizer particles.
19. A method of producing the fertilizer composition of claim 1 , the method comprising:
coating a urea and/or phosphate containing fertilizer particle with a bacteria and a nutrient comprising at least one of an amino acid, a nitrogen source, a phosphorous source, or a sulfur source,
wherein the urea and/or phosphate containing fertilizer particle is a solid particle.
20. A method of fertilizing, the method comprising applying the fertilizer composition of claim 1 to at least one of a soil, a crop, a liquid carrier, a liquid solvent, or a combination thereof.
