Abstract
In embodiments, the present invention relates to liquid formulations containing hydrophobic, biodegradable polymers dispersed within a Non-aqueous Organic Solvent Delivery System (NOSDS) that is designed to coat fertilizer granules with a hydrophobic film utilizing simple application equipment such as mixers, blenders and tumblers. This film can impede the dissolution of fertilizer components by water improving fertilizer efficiency. The NOSDS can be aprotic solvents, protic solvents and mixtures of protic and aprotic solvents which are environmentally friendly, have flashpoints above 145° F., and are inherently rated safe for contact with humans and animals. The hydrophobic polymers are the reaction product of aldehyde(s) and nitrogen containing compounds.
