ABSTRACT
This study provides original data on the impact of human activity on vegetation under the specific conditions of the Kastanozem from the Kostanay region (northern Kazakhstan). Radical changes in land use are provoking deposition in vegetation. The question remains whether natural vegetation will return or whether a different type of vegetation will be created under the specific conditions of the Kastanozems soils. The evaluation of vegetation took place in the fields that were abandoned in different time horizons. Height, cover, biomass weight and species composition of vegetation were monitored. The vegetation of abandoned fields is characterized by low species diversity. Succession runs from annual species to a stage where perennial dicotyledonous species with a deep root system dominate. Spontaneous vegetation leaves a sufficient amount of biomass on the soil surface, which assumes that the land will be protected from undesirable phenomena such as erosion and desertification processes.
