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 (21)

1. A fertilizer composition, comprising:

an ammonium nitrate material;

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 apatite, wherein the stabilizer material is at least 12.5 wt. % of total fertilizer composition.

2. The fertilizer composition of claim 1 , further wherein the fertilizer composition comprises not greater than 25 wt. % of stabilizer material.

3. The fertilizer composition of claim 1 , wherein the fertilizer composition is configured to result in a specific impulse of not greater than 2.12 kPa*ms/kg when measured in accordance with a blast propagation test.

4. The fertilizer composition of claim 1 , wherein the apatite is a hydroxyapatite material.

5. The fertilizer composition of claim 4 , further comprising hydroxyapatite in an amount of 12.5 wt. % of total fertilizer composition, wherein the fertilizer composition results in a specific impulse of not greater than 9.58 kPa*ms/kg when measured in accordance with a blast propagation test.

6. The fertilizer composition of claim 4 , further comprising hydroxyapatite in an amount of 17.5 wt. % of total fertilizer composition, wherein the fertilizer composition results in a specific impulse of not greater than 4.7 kPa*ms/kg when measured in accordance with a blast propagation test.

7. The fertilizer composition of claim 1 , further comprising a filler material.

8. The fertilizer composition of claim 7 , wherein the filler material is selected from the group consisting of: bauxite residue, red lime, fire clay, and combinations thereof.

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

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

11. The fertilizer composition of claim 1 , wherein the fertilizer composition is configured as a mesh size of between 4 and 20.

12. 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.

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

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

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

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

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

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