The content of mineral and mineralizable N in soils (predominantly loam chernozems) in three sites of the beet-growing regions at different fertilization in spring and autumn was investigated. Soil samples were taken from a layer 0 to 25 cm and 25 to 50 cm in autumn and in spring. To determine mineralizable N, aerobic incubation method was used. Lower values of mineral and mineralizable N were found in site where fertilizers were not applied long time and only cereals were cultivated. A marked growth, particularly of mineralizable N, is after manuring together with mineral fertilization and after pea.
