ENVIRONMENTAL ASSESSMENT OF CHEMICAL PROPERTIES OF SOIL OF FOREST ECOSYSTEM

Abstract

The article presents the results of the soil survey of protected area, situated within the pine forest of the Semipalatinsk Irtysh. Soil assessment of index plot has been conducted on a number of chemical parameters, including humus content, pH of the aqueous extract, cation-anion composition, the total amount of water-soluble substances. According to the results of laboratory experiments, the soil of the State Forest Nature Reserve “Semey ormany” can be described as non-saline, non-toxic, neutral or slightly alkaline, with a low humus content.
