Soil contamination - a problem that concerns everyone!

Soil - a natural formation, which has a set of specific properties. The structure of the soil, its composition and the mold formed by complex biological processes over manycenturies. Its main characteristic is the fertility level of which determines whether the soil is able to ensure proper growth and development of plants growing on it. Is there such a thing as natural fertility of the soil, by which is meant the level of nutrients, looseness of the structure and the presence of living organisms in all layers of the soil.


Also, the mold is formed by the accumulation of solar energy that enters into it at the expense of plant photosynthesisImproving soil fertility, remains to be a fairly important issueAt the level of soil fertility has always affected people, and often this effect isdevastating. To date, soil pollution is global in nature and can lead to irreparable consequences. The destruction of topsoil leads inexorably to a breach of natural balance,metabolic in nature. On this basis, we can say that soil contamination can result in the destruction of other ecosystems.
Bulk soil pollution by pesticides
Since ancient times people tried to get the maximum amount of the harvest and used fora variety of tricks. However, if in ancient times, methods of influence on the soil were reduced to tricks and making the processing of some organic fertilizers, today methods of influence on the soil out on a completely different level.













The problems of soil contamination are the result of uncontrolled use of pesticides and herbicides. For the cultivation of various crops are widely used by a variety of chemicals, which lead to the accumulation of toxic substances in the soil layers. It can not affect human health, because the harvest, collected from plants grown in the poisoned soil, also contains particles of these poisons. Based on the increasing incidence of people, and the intensity of soil contamination - biodiagnostika. Pesticides to protect plants from various diseases and allow them to save the harvest. Pesticides directly into the soil, along with seeds and processed for further processing of different cultures. Soil contamination by pesticides is the most widespread. They can be for many years to be in the soil, even if it is clay soil, while not losing its destructive properties. In this land of new microorganisms will not appear for a long time. Current trends are such that people stop using so harmful to the soil and the human body, and prefer to work with pesticides to increase crop yields by other methods. Other methods of soil contamination by pesticides is not only capable of increasing levels of soil contamination. To date, treatment of soil in a variety of technical devices, which leads to the inexorable elements of soil contamination of heavy metals such as lead and mercury. These substances can enter the soil and, together with industrial waste and decomposition products of the pulp and paper industry.


Fine particles of lead can also enter the soil from vehicle exhaustIt is therefore notrecommended to cultivate the land and break the gardens next to the highways.Characterization of sources of soil pollution shows that the main enemy of the soil is aprocess whose products ruthlessly destroy it. But not always for the destruction of thetopsoil has to do with people. For example, soil erosion - a natural phenomenonAt the same time on a regular basis leads to erosion of washout of humus, leaching of nutrientsand disturbance of soil structure. Protection of soil contamination in this case should be the creation of dams and the correct placement of the different cultures that will preventsoil erosionThe soil is fertile layer recovers by self-regulation, but this process can takehundreds of years, and regular soil contamination reduces the results to zero. It is therefore necessary to take measures to restore and cleanse the soil. Only in this case,the mold will not be lost.
