First claim
Opening claim text (preview).
What is claimed is: 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.
