The study of soil agrochemical characteristics of zone soils of coal-mining enterprises of Kemerovo region

In the study the results of soil and agrochemical characteristics of zone soils research were stated (June, 2016). By the results of research of sites of coal mine of the territory of JSC ‘Mine No. 12' of Kiselevsk, Kemerovo Region it was revealed that the surface of a soil cover of sites No. 1 and No. 3 was presented by deep-cespitose deep and thin sod-podzolic heavy loam soils, and site No. 2 was represented by light gray undeveloped skeleton sandy loam soils. The particle size distribution was presented by rather large and dusty silty heavy loam and loam to light. The whole territory of the studied sites of the field was occupied by the birch (Betula pendula) forming close forest stands on the edge of the field extensive thickets of the caragana (Caragana pygmaea). The analysis of these tests shows that the maintenance of humus in the top soil horizon A was 3.1-6.2 %, with depth sharply falls. In the transitional horizon of VS only humus traces were found. The content of gross phospho-rus in the soil was low (0.13 %), with sharply falling depth. The content of gross potassium was an av-erage on the whole profile, and the content of nitro-gen on all sites varied from 0.12 to 0.48 % which was undoubtedly connected with climatic arrange-ment of sites in the district. The reaction of soil so-lution was from weak to strongly acid in lower hori-zons. The maintenance of mobile forms of heavy metals in soil samples did not exceed maximum concentration limit (mg/kg) of their contents in the soil taking into account Clark's classification. Thus, it was revealed that fertile layer of earth (FLE) of the studied sites near operating coal mine was characterized as fertile, but not suitable for removal and storing as the surface of the whole studied field of the territory of the enterprise of Mine No. 12 coal mine strongly wooded, crumpled, with gullies and with a lot of windbreak.
