Sorption and migration of zinc in taiga zone soils in laboratory and field experiments

The parameters of the zinc sorption and migration were experimentally determined under laboratory and field conditions for soils of forest and meadow biogeocenoses of Tver?? oblast. Two methods gave relatively close values for the parameters of the metal??s sorption by an almost neutral loamy sandy soddy soil of a meadow biogeocenosis. The potential capacity of an acid sandy loamy soddy-podzolic soil for zinc sorption determined under laboratory conditions was not completely realized under the field conditions, which was related to the properties of the biogeocenosis (the forest plants, the organization of the soil pore space, and the soil reaction) and the experimental conditions.
