Forest plantations in soil protection from man-made pollution

Pollution of the soil in the course of degradation of lands is caused by presence of anthropogenic chemicals and other changes in the natural soil environment. It is, as a rule, caused by agricultural chemicals, industrial emissions, or often wrong recycling. The most widespread chemicals are hydrocarbons, polycyclic aromatic hydrocarbons (such as benzo (a) pyrene), solvents, pesticides, lead and other heavy metals. Pollution correlates with extent of industrialization and intensity of migration of chemical [3,4,5]. Concern about pollution of soils is connected mainly with risks for health, direct contact with the polluted soil, evaporations from pollutants and secondary pollution of sources of water supply in the soil, transformation in food chains. Restoration of the polluted sites of soils and the cleanings connected with it are the labor-consuming and expensive tasks demanding the large volume of geology, a hydrology, chemistry in the field of environmental pollution. The protective forest plantings landed along farmlands for improvement of a microclimate, snow retention, protection against a ravine education, etc. in certain conditions could protect soils from distribution of technogenic toksikants about whom it was noted above. Biogeocenological researches of protective plantings are directed to a research of the main types of the soils distinguished on the morphological building in various on specific structure of plantings. Work, shows change of structure of soils under a canopy of the protective woods Pre-Volga region and as a result acquisition of new buffer functions by them in an ecosystem. Restoration of the polluted sites of soils and the cleanings connected with it are the labor-consuming and expensive tasks demanding the large volume of geology, a hydrology, chemistry in the field of environmental pollution. Target change of structure of soils in protective strips, selection of the landed species of trees, can become one of methods in the field of decrease in environmental pollution.
