Biological mineralization of organic matter in the modern virgin and plowed chernozems, buried chernozems, and fossil chernozems

Eurasian Soil Science, 2009
The phenomenon of mineralization (biological mineralization) of organic matter in chernozems has been studied. A decrease in the content of Corg with time can be considered an index of the organic matter mineralization. It is suggested that the humus horizons of modern chernozems contain the pools of organic matter of different ages: easily ...

Water–salt regime of chernozems in the Central Chernozem Region

Arid Ecosystems, 2015
With the recent increase in the factor of risky farming in the Central Chernozem Region, there has been a tendency to restore old irrigation systems or create new irrigational systems in many farms of Voronezh oblast. Therefore, a detailed analysis of the water–salt regime of chernozems, which are basic agrocenose components, is of current interest.

Concretions in typical chernozem, gleyed chernozem-like, and solonetzic chernozem-like soils of the southern Tambov Lowland

Eurasian Soil Science, 2014
A system for the diagnostics of chernozemic soils of the Tambov Lowland based on concretions is proposed for agricultural and reclamation purposes. The relationships between the structure and composition of the carbonate concretions, the long-term water regime of the soils, and the productivity of the crops have been established.

The Chernozem Family

2011
Chernozem are well-drained soils with a thick, black topsoil characterized by an extraordinary accumulation of humus, granular structure that renders them friable even when dry and high base saturation, overlying a limey subsoil. They occupy some 230 million hectares in the steppes of Eurasia and Prairies of North America; they grade to chestnut soils (

Chernozem: Soil of the Steppe

2013
Chernozem is the predominant soil of Moldova and the country’s greatest natural treasure. Its profile is very thick, well humified and well structured – properties inherited from the steppe. Only grassland with its many-branched and deeply-ramified root system is able to produce abundant organic matter and humification throughout the solum.

Succession of Chitinolytic Microorganisms in Chernozem Soil

Microbiology, 2005
The chitinolytic prokaryotic and eukaryotic microbial complex of chernozem soil has been investigated in the course of a succession initiated by the introduction of chitin and humidification. The dynamics of the cell numbers of chitinolytic microorganisms and of their biomass was assessed by fluorescent microscopy and by inoculation of selective media.

Phyto-Amelioration of Podzolised Chernozem

2021
Degradation of weakly acidic soils can be counteracted at low cost by phyto-ameliorant crops such as perennial grasses and legumes. This helps to solve three big problems of modern agriculture: the maintenance of soil fertility, improving the agricultural-ecological status of the soils, and providing forage for livestock.

KAMENNAYA STEPPE – THE MEMORY OF CHERNOZEM

Materials of the international youth scientific school-conference "Reproduction, monitoring and protection of natural, natural-anthropogenic and anthropogenic landscapes", 2022
This article discusses the origin of the Kamennaya Steppe Nature Reserve in the Voronezh Region. The reasons for the preservation of this area in an untouched form are analyzed, the importance and relevance of the activities carried out at this object is shown.
