FIELD: nanotechnologies.SUBSTANCE: invention relates to the field of nanotechnology, in particular, to a method for producing nanocapsules, and describes a method for producing nanocapsules of ammonium nitrate phosphate fertilizer in a carrageenan shell. Method is characterized by the fact that ammonium nitrate phosphate fertilizer is slowly added to a suspension of carrageenan in ethanol in the presence of 0.01 g of E472c as a surfactant with stirring at 1,200 rpm, the mass ratio of core: shell in terms of dry matter is 1:3, or 1:1, or 1:2, then 6 ml of hexane are added, the resulting suspension is filtered and dried at room temperature.EFFECT: method provides a simplification and acceleration of the process of obtaining nanocapsules, reducing losses in the production of nanocapsules, and can be used in crop production.1 cl, 3 ex
