The article presents the results of the study of micro fertilizer based on nanoparticles of insoluble compounds of the elements Co, Mn, Cu, Fe on meadow grasses. This fertilizer in doze 100+100 ml/ha added before mowing with NPK increase productivity of cereals and legume grasses as well as a mass of its root system. Seed treatment of hybrid clover and everlasting pea using nanofertilizer stimulate the growth by 27.5-31.3 % compared with a control sample and enhance the energy growth of ryegrass by 30.3 %. Nanofertilizer increases stress resistance of the plants by stimulating the growth of root mass.
