Abstract

Generally, the instant disclosure relates to fertilizer compositions and methods of making and using the same. More specifically, the instant disclosure relates to blast suppressant and/or blast resistant ammonium nitrate fertilizer compositions, as well as methods of making and using the same.

Claims (24)

1. A fertilizer composition, comprising:

an ammonium nitrate material; and

an effective amount of a stabilizer material to result in a specific impulse of not greater than 13.5 kPa*ms/kg when measured in accordance with a blast propagation test;

wherein the stabilizer material comprises a layered double hydroxide, wherein the layered double hydroxide is hydromagnesite, and

wherein the stabilizer material is at least 5 wt. % of the fertilizer composition.

2. The composition of claim 1 , wherein the stabilizer material in the fertilizer composition comprises an additive.

3. The fertilizer of claim 1 , further comprising a filler material, wherein the filler material is selected from the group consisting of: bauxite residue, fire clay, red lime, and combinations thereof.

4. The fertilizer composition of claim 1 , wherein the stabilizer composition is at least 10 wt. % of the total fertilizer composition.

5. The fertilizer composition of claim 4 , wherein the stabilizer composition is at least 12.5 wt. % of the total fertilizer composition.

6. The fertilizer composition of claim 5 , wherein the stabilizer composition is at least 15 wt. % of the total fertilizer composition.

7. The fertilizer composition of claim 6 , wherein the stabilizer composition is at least 20 wt. % of the total fertilizer composition.

8. The fertilizer material of claim 1 , wherein the stabilizer material is no greater than 25 wt. % of the total fertilizer composition.

9. The fertilizer composition of claim 1 , wherein the fertilizer composition is configured as a mesh size of not greater than 100.

10. The fertilizer composition of claim 9 , wherein the fertilizer composition is configured as a mesh size of between 4 and 20.

11. The fertilizer composition of claim 1 , wherein the fertilizer composition comprises a form selected from the group consisting of: pellets; prills; granules; powder; disks; and combinations thereof.

12. The fertilizer composition of claim 1 , wherein the fertilizer composition comprises a homogenous mixture.

13. The fertilizer composition of claim 1 , wherein the fertilizer composition comprises a heterogeneous mixture.

14. The fertilizer composition of claim 1 , wherein the fertilizer composition comprises at least one coating.

15. The fertilizer composition of claim 1 , wherein the fertilizer composition comprises a blast suppressant fertilizer.

16. The fertilizer composition of claim 1 , further comprising a desensitized fertilizer.

17. The fertilizer composition of claim 1 , further comprising a plant nutrient selected from the group consisting of: N, P, K, Mg, Ca, Fe, Mn, and combinations thereof.

18. The fertilizer composition of claim 1 , further comprising a binder.

19. The fertilizer composition of claim 1 , wherein the stabilizer material is a Bayer process byproduct.

20. The fertilizer composition of claim 1 , wherein the stabilizer material is naturally occurring.
