The present invention relates to compositions of micronutrients and organic compounds to be used in the treatment, coating and encrustation of seeds of cultivated plants, such as: a Brachiaria spp. (Brachiaria brizantha, Brachiaria decumbens, Brachiaria humidicola, Brachiaria mutica, Brachiaria ruziziensis, Brachiaria arrecta, Brachiaria dictyneura), Panicum spp. (Panicum maximum), Sorghum spp., Pennisetum americanum, Glycine max, Zea mays, Gossypium hirsutum, hortaliças (Solanum lycopersicum, Allium cepa, Lactuca sativa, Daucus carota, Capsicum annuum), florestais (Eucalyptus spp., Tectona grandis, Hevea brasiliensis, Pinus sp.), Nicotiana tabacum, ornamentais, Crotalaria spp. (Crotalaria juncea, Crotalaria spectabilis, Crotalaria ochroleuca, Crotalaria paulina, Crotalaria breviflora). Pertaining to the technical field of agricultural technology, these compositions are associated with the assistance and stimulation of the process of biological nitrogen fixation in the crop cycle, and advantageous in the event of abiotic stresses, mainly in the establishment and germination of the crop and stimulation of the plant growth provided by the components thereof. Particularly, the formulations are combinations of cobalt, molybdenum, nickel, amino acids, plant extracts and algae extracts, within the variations and proportions thereof, together with additives and excipients for improving the formulation of the product.Le présent brevet d'invention concerne des compositions de micronutriments et de composés organiques à utiliser dans le traitement, le recouvrement et l'incrustation de graines de plantes cultivées telles que : Brachiaria spp. (Brachiaria brizantha, Brachiaria decumbens, Brachiaria humidicola, Brachiaria mutica, Brachiaria ruziziensis, Brachiaria arrecta, Brachiaria dictyneura), Panicum spp. (Panicum maximum), Sorghum spp., Pennisetum americanum, Glycine max, Zea mays, Gossypium hirsutum, légumes (Solanum lycopersicum, Allium cepa, Lactuca sativa, Daucus carota
