6 . The composition of claim 4 , wherein the crop nutrition active ingredient includes the nitrification inhibitor, the nitrification inhibitor including at least one selected from the group of dicyandiamide and 2-chloro-6-(trichloromethyl)-pyridine.
7 . The composition of claim 1 , further including a surfactant.
8 . The composition of claim 1 , further including a second solvent, the second solvent including at least one selected from the group of an aromatic hydrocarbon solvent and an aliphatic hydrocarbon solvent.
9 . The composition of claim 1 , wherein a concentration of the crop nutrition active ingredient is from 5 weight percent to 75 weight percent of the composition.
10 . The composition of claim 1 , wherein when stored at 4° C., the composition is stable for at least 13 days.
11 . The composition of claim 1 , wherein when stored at 50° C., the composition is stable for at least 34 days.
12 . A composition comprising:
a first solvent including a caprolactam-derived solvent, the caprolactam-derived solvent according to the general formula:
wherein R is a linear, branched, or cyclic alkyl group of 1 to 6 unsubstituted or substituted carbons and R 1 are independently selected from the group consisting of: H or an alkyl group with substituted or unsubstituted carbons;
a crop nutrition active ingredient dissolved in the first solvent
a second solvent; and
a surfactant.
