Abstract

An improved composition comprising a non-UFP solid carrier and an active agent, such as NBPT, and optionally other components is used as an additive for liquid and solid fertilizers, typically containing urea. Methods of making the compositions and their use are also disclosed.

Claims

1. A composition comprising

a) from about 30% to about 70% of an active agent and

b) from about 70% to about 30% by weight of non-UFP solid carrier based on the total weight of the composition.

2. The composition of claim 1, wherein the active agent is a urease inhibitor.

3. The composition of claim 1, wherein the active agent is N-(n-butyl)thiophosphoric triamide (NBPT).

4. The composition of claim 1, wherein the active agent is a nitrification inhibitor.

5. The composition of claim 1, wherein the nitrification inhibitor is dicyandiamide (DCD).

6. The composition of claim 1, wherein the active agent is a pesticide.

7. The composition of claim 5, wherein the NBPT in the range of about 0.4% to about 15%, the amount of the non-UFP solid carrier is about 0.6% to about 40%, and the amount of the DCD is from about 40% to about 95% based on the total weight of the composition.

8. The composition according to claim 1, further comprising one or more components selected from the group consisting of a conditioner, a dye, and xanthan gum.

9. The composition of claim 1 wherein the non-UFP solid carrier comprises one or more components selected from the group consisting of an ammonium salt, an inorganic salt, a vegetable flour, a diatomaceous earth, a natural clay and elemental sulfur.

10. The composition of claim 8, wherein the inorganic salts is selected from the group consisting of copper sulfate, iron sulfate, magnesium sulfate, hydrated calcium sulfate (gypsum), aluminium sulfate and silicon sulfate.

11. The composition of claim 8 wherein the grain flour is selected from the group consisting of corn, rice, wheat, barley, sorghum, millet, oat, triticale, rye, buckwheat, fonio and quinoa.

12. The composition of claim 8 wherein the natural clay is selected form the group consisting of tonsteins, bentonites;

kaolinites; and

montmorillonites.

13. The composition of claim 8 wherein the diatomaceous earths is selected from the group consisting of Celatom MN84, Tripolite, Perlite, Zeolite and Celite.

14. The composition of claim 1 where a majority of the non-UFP solid carrier has a particle diameter in the range of about 150 μ

m to about 10 μ

m, possibly having a small population below 10 μ

m.

15. The composition of claim 1, made by a process comprising contacting the non-UFP solid carrier with a solution of said active agent active agent in a solvent under conditions including elevated temperatures and sub-atmospheric pressures thereby forming said composition.

16. The composition of claim 15, wherein the solvent is selected from the group consisting of an amide, a glycol, an amine, an alcohol, a hydroxy alkyl amine, an alkylene glycol alkyl ether, a carboxylic acid, a carboxylic ester, or derivatives thereof.

17. The composition of claim 1, further comprising urea, wherein said urea is present in an amount between about 90% and about 99% by weight, said active agent is present in an amount between about 0.02% and about 0.5% by weight.

18. The composition of claim 1, further comprising an aqueous solution of urea ammonium nitrate (UAN), wherein said urea is present in said aqueous solution in an amount between about 24% and about 32% by weight, said ammonium nitrate is present in an amount between about 34% and about 42% by weight, said active agent is present in an amount between about 0.01% and about 0.4% by weight, and said dicyandiamide is present in an amount of about 0.01% to about 2.0% by weight.

19. The composition of claim 14 prepared by blending or mixing the composition of claim 1 with the other components.

20. The composition of claim 14, wherein the composition is a granular fertilizer.

22. A method of making a composition of claim 1 by contacting the active ingredient with the non-UFP solid carrier.

23. A method of enhancing the growth of plants by applying to soil a composition of claim 20.

21. The composition of claim 21, wherein the diameter of the granules of said granular fertilizer ranges from about 0.80 to about 4.8 millimeters.
