The present invention relates to novel urea-formaldehyde polymers coated with an active ingredient, a method of making the same, and their use.

Process for coating an active ingredient with a urea-formaldehyde polymer

A dry flowable additive for aqueous urea-based fertilizers made of solid urea formaldehyde polymer (UFP), N-(n-butyl)thiophosphoric triamide (NBPT), and, optionally, dicyandiamide (DCD), wherein the liquid fertilizer containing the additive provides reduced nitrogen loss from the soil. Optionally, the dry additive may also be blended with molten or solid urea to form a solid urea-based fertilizer with reduced nitrogen loss from the soil.
