Abstract RU 2193018 C1

FIELD: agriculture. SUBSTANCE: method involves using suspension carbon finely dispersed in aqueous solution; introducing suspension into boiled out fertilizer pulp prior to feeding pulp to pelletizer in an amount of 0.2-1.0 kg per 1 t of product. Fertilizer has stable color of required intensity, which does not disappear during pelletizing and drying of phosphorous and nitrate fertilizers without deteriorating physicomechanical properties of fertilizers. Method is used in production of fertilizers with distinctive color, in particular, compound nitrogen-phosphate fertilizers. EFFECT: increased efficiency and simplified method. 1 tbl, 3 ex
