Method for Obtaining Biocompatible Organic Nanostructures, Biocompatible Organic Nanostructures, Agrochemical Composition and Their Uses The present invention is for a method of obtaining biocompatible organic nanostructures by the steps of (a) preparing an aqueous solution with high concentration of micronutrients and / or nutritional elements and controlled temperatures and pressure; (b) adding the encapsulation system to the aqueous solution of step (a) in a ratio of from 3.0% to 20.0% by weight of the final mixture, under slow agitation at 30 to 60 rpm, wherein the encapsulation system It is composed of natural, synthetic and / or semi-synthetic phospholipids and, optionally, surfactants, stabilizing organic elements, among others; (c) a first mechanical agitation for about 30 to 120 minutes at speeds between 20 and 60 rpm and then a second agitation at speeds greater than 1,300 rpm and a pressure greater than 5 bar until complete homogenization and, returning mixing at the conditions of the first stirring at ambient pressure; (d) cooling the mixture to temperatures below 20 ° C for about 3 to 6 hours, (e) diluting the mixture to about 15 to 50% of the final total solids concentration and (f) adding non-toxic microbiological preservatives . In addition, the patent application relates to a biocompatible organic nanostructure obtained by the method described above, said nanostructure comprising natural, synthetic and / or semi-synthetic phospholipids and optionally surfactants, water soluble and organic stabilizing elements and / or agents. non-toxic microbiological preservatives. Also, the invention provides an agrochemical composition containing said nanostructure of the present invention and its uses in the agricultural environment as vectors of transport of bioactive substances.método de obtenção de nanoestruturas orgânicas biocompatíveis, nanoestruturas orgânicas biocompatíveis, composição agroquímica e seus usos a presente invenção é destinada a um método de
