Abstract: The present invention relates to increasing and/or maintaining nitrogen content in soil by administration of nitrogen sources particles coated with urease inhibitors. In one embodiment, urease inhibitors are dispersed in an improved organo liquid delivery system at concentration levels of 60-95%.

Abstract: Animal waste contains most of the essential nutrients required for plant growth. However, animal waste also contains microbes that convert urea to ammonium ions, nitrification of the ammonium ions to NO2 and NO3 and denitrification of NO2 or NO3 to N2. N2O is produced as an intermediate of nitrification and denitrification processes and N2O is a 300 times more potent greenhouse gas than CO2. The instant invention discloses low-cost, fluid suspension compositions comprising a combination of urease, nitrification and denitrification inhibitors that decrease the loss of nitrogen from animal waste and lessen the biological formation of the greenhouse gas N2O. These compositions comprise nitrogenous phosphoryl compounds and nitrification inhibitors that utilize manufacturing processes for the formation of low cost, fluid suspensions comprising one or more inhibitor particles selected from the group consisting of urease inhibitor particles, b) nitrification inhibitor particles, and c) fused particles.
