abstract


It is shown that the рН values of water extracts of seven names of the studied soils are within the limits regulated by technical regulations. For a sample «The dream of the botanist» рН is equal to 4,68 and less than admissible value 5,5.

The greatest value of specific conductivity and the general mineralization of a water extract is characteristic for a soil sample «Gaspadar. Wonderful tomato », used for cultivation of the tomatoes seedlings.

The content of Hg, Zn, Cd, Pb and Cu in extracts of artificial soils was investigated by stripping voltammetry method. It is established that in extracts of all studied samples of soils the content of Zn, Cd, Pb and Hg does not exceed the regulated values. Copper in small amounts is found only in extract of a sample of TERRA VITA soil.
