The present invention relates to increasing and/or maintaining nitrogen content in soil by administration of granular or powdered nitrification inhibitors coated with urease inhibitors. In one embodiment, urease inhibitors are dispersed in an improved organo liquid delivery system at concentration levels of 50-90%. In another embodiment, urease inhibitors were applied in a non-aqueous, organo liquid delivery system coating solid nitrification inhibitors utilizing simple blending equipment at temperatures of 20-70 C. Another embodiment discloses a dry, flowable additive containing a nitrification inhibitor coated with a urease inhibitor which can be administered directly to the soil, to a dry natural and/or a manmade fertilizer or to a liquid fertilizer which provides for the reduction of nitrogen loss from the soil.

The present invention relates to a field of chemical engineering and in particular to a method for continuously pelletizing water-soluble solids, comprising steps of: a) feeding raw material and seed particles to a pelletizing disc; b) pelletizing water-soluble solids during wetting with an aqueous phase; c) removing pelletized product from the pelletizing disc; d) drying the pelletized product from step c); e) dividing the dried pelletized product from step d) into fractions; e) removing the commercial fraction from the process, characterized in that in step e), the dried pelletized product from step d) is divided into four fractions: a commercial fraction having a pellet diameter in the range of D.sub.1 to D.sub.2; a coarse fraction having a pellet diameter>D.sub.2; a recycled fraction having a pellet diameter in the range of

[00001]$\frac{D_1+D_2}{9}$

to D.sub.1; and a fine fraction having a pellet diameter in the range of

[00002]$<\frac{D_1+D_2}{9};$

wherein the recycled fraction is fed as the seed particles to the raw material feeding step a), the coarse fraction is fed for grinding to a particle diameter in the range of

[00003]$\frac{D_1+D_2}{9}$

to D.sub.1 and then recycled to the process at the raw material feeding step a), the fine fraction is fed for grinding until there are no pellets having the size exceeding the particle size of the raw material, and also recycled to the raw material feeding step a), wherein the raw material particle diameter is

[00004]$<\frac{D_1+D_2}{44}.$
