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.

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 ...

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.

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.

Mobile Phosphorus Presence of Typical Chernozems on Fertiliser System

Rural Sustainability Research
Due to the systematic utilisation of substantial amounts of phosphorus fertilisers on agricultural crops in crop rotation, the amount of available phosphate compounds increases in the soil. It ensures the maximum increase in crop yields. The study of the

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 (

Mineralogical properties of chernozem and chernozem-like soils in Eastern Croatia

7th Croatian Geological Congress with international participation: book of abstracts, 2023
The subject of this study are the soils near the Dalj settlement and Zmajevac settlement (Eastern Croatia). The aim of this work was to determine the mineralogical properties of chernozem and chernozem-like soils in order to observe possible differences between the soils and their parent material and to better understand weathering processes in them ...

Assessing the vegetation history of european chernozems through qualitative near infrared spectroscopy

Quaternaire, 2019
Chernozems are considered to be typical soils of continental steppe environments. Nonetheless, they exist in many areas in Central Europe, where the climate is convenient for the growth of trees and forest vegetation.

Origins of hard carbonate nodules in arable Chernozems in the Central Russian Upland

European Journal of Soil Science, 2020
The genesis of hard carbonate nodules in the lowermost horizons (180–200 cm) of arable soils in the southern part of the forest‐steppe region of the Central Russian Upland was associated with a change in soil water regime.

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.
