FIELD: technological processes.
SUBSTANCE: invention relates to the production of encapsulated fertilizers. Method for preparing nanocapsules of ammonium nitrate phosphate fertilizer involves the adding of ammonium nitrate phosphate fertilizer to a suspension of sodium alginate in butanol in the presence of 0.01 g of preparation E472c as a surfactant and stirring at 1,200 rpm. Mass ratio of the core: the shell when recalculating to dry matter is 1:3, or 1:1, or 1:2. Then 5 ml of chloroform are added to the resulting mixture. Produced suspension is filtered and dried at the room temperature.
EFFECT: proposed method of the preparation of nanocapsulated ammonium nitrate phosphate fertilizer provides a simplification and acceleration of the process of obtaining nanocapsules and an increase in yield by mass.
