soil - one of the elements of the biosphere, providing circulation of chemicals in the surrounding ecosystem.This applies to both endogenous and exogenous to the chemicals that enter into it with waste water, emissions of industrial enterprises, road and air transport, as well as fertilizers.
a consequence of anthropogenic activity of man, the soil becomes a place to store a large amount of harmful substances.Because she, unlike other natural environments, has no mobility, it is much more susceptible to contamination.In addition, getting the soil, many of the compounds as a result of microbiological and chemical transformations are even more toxic than the original.
The danger is that the ground can be a source of pollution of air, water, food and other elements of the biosphere radioactive and carcinogenic substances.It is therefore important to carry out regular monitoring of the soil envelope, and especially the analysis of the soil, which is a set of laboratory tests to determine the physical-chemical, chemical, mechanical, biological and agrochemical properties.
The main types of soil analysis: microbiological, chemical, mineralogical, mechanical (particle size).Their main purpose is to ascertain the number and type of pollutants, as well as to determine their source.Sometimes, however, a soil analysis is performed to detect the presence of disease-causing parasites in it.This analysis is called bacteriological, and its main task is to detect different pathogens of humans and animals.
more complete sanitary-bacteriological test is carried out for a deep and detailed characterization of soil suitability to accommodate housing, child care, recreation, water supply facilities, for epidemiological studies, the definition of general health condition of the soil.
One of the most basic types of research is a chemical analysis of the soil, which helps to identify its content of metals, including heavy (C, Mg, Fe, Co, Cr, Zn, etc), chemicals (carbonates, sulphates, chlorides).It is very important from the point of view of ecology.
In order to determine the level of fertility of the land, held agrochemical analysis of the soil.It allows you to assess whether the plants are provided with batteries, there is a need for fertilizers, in conducting chemical reclamation and other activities.These figures help to clarify the potential of the fertile layer.
complete soil analysis involves a lot of research.To assess specific land obtained results are compared with the optimum standard indicators of content items that for this type of soil was determined experimentally and tested in a production environment.Soil analysis ends with the issuance of conclusions about its actual condition and recommendations for the use and improvement.
