ФИЗИЧЕСКИЕ, ВОДНО-ФИЗИЧЕСКИЕ И АГРОХИМИЧЕСКИЕ СВОЙСТВА ПОЧВЫ ОПЫТНОГО УЧАСТКА, ЗАЛОЖЕННОГО НА ТЕРРИТОРИИ РИДДЕРСКОГО ЦИНКОВОГО ЗАВОДА

Abstract

As a result of research have revealed that the main source of pollution of a skilled site is the zinc plant. The area of distribution of emissions of plant in circles makes 2 km, with special influence on a wind rose in east direction from plant towards the city. In the territory in a radius of 2 km strong influence of emissions of plant on a soil and vegetable cover which is subjected to strong erosive processes is revealed. Analyses of water physical properties have shown that humidity of soils increases with depth (20 - 30 cm). Increase in volume weight in soils near zinc plant is explained by significant influence of TM. They destroy composition of organic acids that respectively influences an aggregate state, there is an increase in thin fractions, from PPK the absorbed calcium is forced out, units collapse and there is a consolidation, especially top horizons. The low maintenance of a humus is explained by the fact that on a surface of chernozems practically all vegetable communities have disappeared. Security of soils with absorbing forms of nitrogen and mobile phosphorus is low. Content of mobile potassium is high.
