The assessment of the content of copper and zinc in the system soilplanton the example of Oktyabrsky district of Khanty-Mansi autonomous area - Yugra

Copper and zinc are the most important trace elements involved in many biochemical and physiological processes of plants, animals and humans. For living organisms, both their excess and lack are dangerous. The purpose of the study was to determine the content of copper and zinc in the soils and vegetable crops of the territory of Oktyabrsky district of Khanty-Mansi Autonomous Area - Yugra. The study area was Oktyabrsky district of Khanty-Mansi Autonomous Area - Yugra, localities: Ob, Peregrebnoe, Unyugan and Bolshye Leushi. The research was conducted in 2018-2019. In these territories, soil samples were taken from homestead plots and agricultural plants (potatoes, carrots, table beets). The soils used for cultivation of agricultural crops on the homestead plots are agropodzolic. The average content of mobile forms of copper and zinc in the studied soils is characterized as low for Cu, and optimal for Zn close to permissible concentration. The values of copper in plants vary in the following ranges 0.04-0.13 mg/kg. Zinc content is 0.2-0.83 mg/kg. Based on all the data obtained, one can make the conclusion that there is a deficit of copper and zinc in vegetable crops. The coefficient of biogeochemical mobility of copper and zinc is studied, which varies widely from 0.01 to 0.8. The content of copper and zinc and their biogeochemical mobility depend on the type of soil, the biological characteristics of the culture, the level of anthropogenic load in the study area.
