The study concerns with biogeochemistry of landscapes in the Yamal Peninsula, including the trace-element composition of different soils and abundances of plant nutrients. The sustainability of plant-soil systems in permafrost terrains has been recognized to have two major controls: the biosorption activity of plants and contents of biogenic elements in soils. The former factor stabilizes the material composition of landscapes and shows up especially in zonal systems. The other factor controls the rate of revegetation in industrially disturbed areas, the azonal soils being best provided with mineral nutrients.
