Abstract: Fertilizer particles described herein include a powder composition that can contain one or more urease inhibitors and/or nitrification inhibitors and a filler material embedded within a solid urea matrix. Methods of producing the fertilizer particles involve contacting a powder composition that can contain one or more urease inhibitors and/or nitrification inhibitors and a filler with molten urea under conditions sufficient to form a fertilizer particle having the powder composition embedded within a solid urea matrix.

Abstract: Particulate fertilizer compositions that include nitrification inhibitors and urease inhibitors are described herein. The inhibitors are separated from each other by being in separate particles. Fertilizer particles in the composition include particles having a core-shell structure, with an inhibitor included in the core particle.
