Sorption, Transformation and Migration of Zn in Some Soils with Percolated Water Regime

There were determined the parameters of applied Zn sorption by two taiga soils with different properties, composition of their formed species and the migration of their available ones. The laboratory and field experiments were used in this work. Laboratory experiments have identified the great potential absorption capacity of soils (especially of the upper organic horizons) towards applied zinc and ability to retain it relatively firmly. But this ability is not fully realized in artificial pollution under field conditions. This proves that the upper soil horizons are indeed a “critical area” of the crust even in the soils with percolated water regime.
