Abstract
An improved composition comprising substantial spherical UFP particles and an active agent, such as NBPT, and optionally other components is used as an additive for liquid and solid fertilizers, typically containing urea. Methods of making the compositions and their use are also disclosed.
Claims18
A composition comprising
- a) from about 30% to about 70% of an active agent and
- b) from about 70% to about 30% by weight of substantially spherical urea-formaldehyde polymer (UFP) particles based on the total weight of the composition;
- wherein a majority of the substantially spherical UFP particles have a particle diameter from about 10 μm to about 150 μm.
