The treatment of winter wheat, grown on ordinary carbonate chernozem with humic fertilizer «BIO-Don»

, , , , &
A comparative analysis of the two methods of determining the total humus content in the soil was carried out: an indirect Tyurin’s method (modification by Simakov), and modification according to State Standart 26213-9 were compared with a method of high-temperature catalytic combustion in the analyzer of total organic carbon (TOC-L CPN Shimadzu). It is shown that the determination of the total soil humus content by Tyurin’s method and as described in State Standard 26213-9 gives...

Soil-like formation in technogenic landscapes history of study, terminology, modern aspects (review)

Intensive mining and industrial processing are inevitably accompanied by withdrawal of agricultural and forest land from the turnover. Alienation of land under mining in Siberia is accompanied by loss of the most fertile soils. Within historically formed soil areas technogenic landscapes appear, most of them result from piles of waste rocks. Their surface is weathered, leached, and gets populated with biota over time. Soil-like bodies are formed of these mineral substrates. They are characterized by...
