Semenova I.N., Suyundukov Ya.T. EVALUATION OF SIBAY SOIL TOXICITY BY AZOTOBACTER CULTUREWith the culture of Azotobacter assess the toxicity of ordinary chernozem of the Republic of Bashkortostan Sibai which are subject to influence from the mining factory. Nitrogen-fixing Azotobacter culture grows in soils analyzed in different ways, the differences observed in the growth rate, the percentage of fouling soil lumps and the diameter of the colonies. This difference may be due to different levels of heavy metals in soils of the city.Key words: black soil, heavy metals, the biological activity of soils, Azotobacter and mining.
