The influence of organic and mineral elements of nutrition on the ratio of the essential oil components of Mentha piperita L. cultivars growing on sodpodzolic soils of the Moscow region was studied. The essential oil from raw materials Mentha piperita L. high-menthol and low-menthol cultivars (Medichka, Lekarstvenaya 4, Jantarnaya, Zgadka, Kubanskaya 6, Moskvichka) was investigated. The organic fertilization in the form of peat compost in the dose 125 t/ha was applied. The lime (CaCO3) was applied in the form of dolomite flour at the dose 5 t/ha. The mineral fertilizers (NPK) namely Universal -2 enriched with trace elements in the dose N51.4P34.3K60 kg/ha was used. The contents of more than one hundred terpenoid compounds with a concentration from 80 to 0.001 % in the M. piperita L. essential oil was found. The ratio of components in the essential oil varies due to Mentha piperita cultivar-specifically. There at, all identified components present in the oil of all cultivars indicating genetic stability of this species essential oil composition. The sod-podzolic soils cultivation has a positive effect on the essential oils quality of studied mint varieties. Notably, set the main components of peppermint oil remains constant with some changes in their quantitative content upon application of organic and mineral fertilizers and lime. The elongation interphase periods and deadlines for the phenological phases under the action of fertilizers for low-menthol cultivars (Kubanskaya 6, Jantarnaya) is observed. Resulting, the genetic potential accumulation of menthol in the essential oil was not fully realized. The application of mineral fertilizers has a positive effect on the essential oil qualitative composition of high-menthol cultivars (Medichka, Lekarstvennaya 4, Moskvichka, Zgadka).
