Abstract

The nutrient concentration of nitrogen, phosphorus and potassium in a soil cover can be considered as a soil fertility indicator and diagnostic characteristic of the changes because of the influence of technogenic pollution in the urban environment. The study of the total content of labile soil nutrients, their migration ability in the soil profile and seasonal content dynamics reveales some special soil features of industrial, residential, grassland and forest landscapes in Arkhangelsk in dependence to the level of human impact. The maximal anthropogenic load in the industrial landscape causes the change of total nutrient content, especially labile soil potassium: 90 % of sampling areas have a high content of it, and 10 % – a very high content. Decreasing series of nutrient accumulation in soils of the unpolluted territory, in forest and residential landscapes is as follows: P > K > N. Potassium predominates in soils of industrial and grassland landscapes in terms of accumulation: K > P > N. This may be due to the anthropogenic impact of industrial landscape and features of floodplain soils in the grassland landscape. The nature of elements migration in the soil profile significantly changes: the proportion of humus-illuvial accumulation increases in soils of industrial landscape, while the less polluted landscapes are characterized by the accumulation in the surface humic layers. Seasonal dynamics of nutrients distribution changes. In soils of the industrial areas by the end of a growing season the accumulation of phosphorus and potassium is observed, which seems to have a technogenic origin. A steady decline in the concentration of these elements is marked in the unpolluted and natural-anthropogenic territories.
