Claim 16:
17. A fertilizer composition comprising:
a) one or more nitrogen sources selected from the group consisting of i) ammonia, and ii) pressurized anhydrous ammonia gas,
b) a liquid fertilizer additive composition comprising i) one or more liquid biodegradable polymeric and/or oligomeric nitrification inhibitors selected from one or more of structures consisting of:, wherein R43, R44, R45, and R46 are one or more members independently selected from the group consisting of: H and —CH2OH wherein at least one of R43, R44, R45, and R46 is —CH2OH,, wherein R47, R48, R49, R50, R51, and R52 are one or more members independently selected from the group consisting of H, and —CH2OH,, wherein R53, R54, R55, R56, R57, R58, R59, and R60 are one or more members independently selected from the group consisting of: H and —CH2OH, and, wherein R61, R62, R63, R64, R65, R66, R67, and R68 are one or more members independently selected from the group consisting of H and —CH2OH, wherein x is 2-20, and

ii) a reaction medium comprising one or more non-aqueous polar, aprotic organic liquids,
iii) one or more organo polyorganic acids and/or their salts, wherein the organo polyorganic acids and/or their salts is a homopolymer of aspartic acid, and
iv) one or more biologically active agents, wherein the one or more biologically active agents comprise (1) 2-chloro-6-(trichloromethyl)pyridine, and (2) dicyandiamide
wherein the fertilizer composition comprises 0.05-10% of the liquid fertilizer additive, wherein said one or more liquid biodegradable polymeric and/or oligomeric nitrification inhibitors are made by using non-aqueous reaction conditions including said reaction medium, and wherein the fertilizer composition comprises more than 10% by weight of the one or more liquid biodegradable polymeric and/or oligomeric nitrification inhibitors.
