Abstract
An improved nitrification inhibitor composition comprising UFP particles and a nitrification inhibitor, and optionally other components, is used as an additive for liquid and solid fertilizers, typically containing urea. The nitrification inhibitor particularly can be nitrapyrin and/or DMPP. Methods of making the compositions and their use are also disclosed.
