Disclosed are compositions and methods of making a liquid fertilizer additive solution of polymeric and/or oligomeric heterocyclic nitrogen containing nitrification inhibitors comprising a non-aqueous polar, aprotic organo liquid (NAPAOL) as the reaction medium for the reaction of aldehyde(s) with heterocyclic nitrogen containing nitrification inhibitors that have one or more aldehyde reactive groups selected from the group consisting of a) primary, b) secondary amines, c) amides, d) thiols, e) hydroxyls and f) phenols. Fertilizer compositions are disclosed comprising of a) one or more polymeric and/or oligormeric heterocyclic nitrogen containing nitrification inhibitors adducts from the reaction of aldehyde(s) with heterocyclic nitrogen containing nitrification inhibitors that have one or more aldehyde reactive groups selected from the group consisting of a) primary, b) secondary amines, c) amides, d) thiols, e) hydroxyls and f) phenols b) a non-aqueous organo solvent delivery system (NOSDS), and c) one or more nitrogen sources.

Hydrate inhibitor and corrosion inhibitor composition are disclosed and include from about 10 wt-% to about 99.9 wt-% of an anti-agglomerant low dose hydrate inhibitor (AA-LDHI), wherein the AA-LDHI is a zwitterionic compound or a cationic ammonium compound; from about 0.01 wt-% to about 50 wt-% of a corrosion inhibitor, and at least one additional functional ingredient, solvent, or a combination thereof. Methods for inhibiting corrosion and formation of gas hydrate agglomerants in a fluid are disclosed and include contacting the fluid with a hydrate inhibitor and corrosion inhibitor composition or contacting the fluid with an AA-LDHI, wherein the AA-LDHI is a zwitterionic compound or a cationic ammonium compound, and a corrosion inhibitor, wherein the AA-LDHI and corrosion inhibitor are provided at a weight ratio of about 1:0.001 to about 1:1, and wherein the composition inhibits general and localized corrosion and formation of gas hydrate agglomerants in the fluid.
