Zusammenfassung:Use of an oil-based composition comprising boron-containing particles, for the reduction of ammonia volatilization upon application of urea-based fertilizer particles to soil, wherein the urea-based fertilizer particles are coated with the oil-based composition comprising boron-containing particles prior to their application to soil; characterized in that the boron-containing particles essentially consist of a material with a low water solubility of less than 10 g/L at 25 DEG C; and at least 95 % of the boron-containing particles have a particle size in the range of 0.1 and 60 [mu]m, as measured by laser diffraction analysis. Use of urea-based fertilizer particles coated with an oil-based composition comprising boron-containing particles for the reduction of ammonia volatilization upon application of the urea-based fertilizer particles to soil, characterized in that the boron-containing particles essentially consist of a material with a low water solubility of less than 10 g/L at 25 DEG C; and at least 95 % o
