Disclosed are compositions and methods of making a liquid fertilizer additive of biodegradable polymeric and/or oligomeric nitrification inhibitors comprised of utilizing a non-aqueous polar, aprotic organo liquid (NAPAOL) as the reaction medium for the reaction of aldehyde(s) with cyano-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.

A system and method for providing fertilizer for crop production in an aqueous solution comprising nano-sized fertilizer particles, which are free of any chemical side chain and free any micelle to protect the nano-sized particle from re-agglomeration, suspended therein for improved uptake by the population of the crop.

A method for fabricating a dry composition is disclosed including combining a solid carbonate or a solid bicarbonate compound, a solid acid yielding compound, a biostimulant, and a plant nutrient. The dry composition may be processed into a tablet, dry powder, meal, or pellets and produce effervescence when a liquid, such as water or a water-based liquid is mixed with the dry composition.
