FIELD: agriculture.
SUBSTANCE: method of producing a composition of sulphur-urea fertilizer includes: feeding a first feedstock containing molten elemental sulphur, a second feedstock containing molten urea and a third feedstock containing a multifunctional ionic surfactant; combining first and second feedstock to obtain combined feedstock; direction of combined raw material to mixing stage for production of mixed raw material; wherein mixing step is carried out using several mixers, including static mixer and dispersion mill with high shear rate, and direction of mixed raw material to treatment step to produce sulphur-urea fertilizer composition.
EFFECT: invention reduces biuret formation in fertilizer compositions.
