Moreover, granules have a size in the range of 0.1-2.5 mm and contain particles, a size of which is in the range of 0.1-20 microns. A method for the production of the nutritional and enriching composition for agricultural crops in the form of granules dispersed in water includes: grinding of the mixture of elementary sulfur in the range of 1-90% by the weight of the entire composition, at least one of iron salts, complexes, derivatives, or mixtures thereof in the range of 1-70% by weight of the entire composition, and at least one dispersing substance in the range from 1-30% by weight of the entire composition in water to obtain a suspension or a wet mixture. Next, the wet mixture is dried to obtain a composition in the form of granules dispersed in water. Moreover, composition granules are in the range of 0.1-2.5 mm and contain particles, a size of which is in the range from 0.1 micron to 20 microns.

EFFECT: invention allows for an increase in bioavailability of granules for absorption by plants, as well as an increase in the yield of agricultural crops.
