Abstract

In 1920s, systematical and very intensive studying and exploitation of natural resources of Far North of Russia has been started. Due to the development of industry and growth of the population, necessity in localization of food support products was growing intensively and arable soils became typical component
of the subject of study. Nowadays, however, almost all the former agricultural lands are abandoned or exposed to various anthropogenic activities from time to time. Abandoned agricultural soils in sub-urban territories of Salekhard were studied with the aim to evaluate the alteration of soil morphology and
chemistry under agricultural practices and to clarify its specificity in case of permafrost-affected soils. Predominance of sandy textured parent materials was found as one of the main reason for favorable agricultural using of land in the north of Western Siberia in previous years. Soil organic carbon content
depended mainly on the character of current land use and varied significantly in the studied soils. Most of the soil samples showed the highest levels of nutrients in topsoil horizons. Former arable horizons were stable in time in terms of morphological features and agrochemical state. In spite of the high level of soil
acidity, content of nutrients in anthropogenically affected topsoils was still high after 20 years of abandonment. This indicated that agrosoils with relatively high fertility of arable topsoils could exist during long time in case of sandy textured parent materials.
