The basic regularities of the distribution of heavy metals’migration pedogeochemical barriers in soil profile of the chernozems ordinary and southern at Kryvy Rih mining and metallurgical regions were analyzed. It was pointed out that heavy metals’migration pedogeochemical barriers is a part of the soil horizon or soil profile, where there is a significant concentration of individual chemical elements as a consequence of the substitution-reaction phenomenon. Pedogeochemical barriers are classified into five types: mechanical, physical, physical and chemical, chemical and biological. The spread

Modern studies of chernozem soils in the northwestern Black Sea region have shown intense dehumification due to disruption of biogeochemical cycles caused by anthropogenic removal of organic matter and associated biophile elements. At former time, the humus zoning was typical for southern chernozems and now we noted the smoothing of this zoning. Acid-base buffering has a significant role in counteracting degradation processes, the buffering parameters could be integral indicators of soil chemicals balance. We studied the automorphic soils (arable chernozems) of the northwestern Black Sea regio

Changes in soil carbon stocks have a significant impact on atmospheric CO2 concentrations and the global carbon balance. Despite the proven effectiveness of agroforestry in erosion control and prevention of soil fertility loss, there are many controversial data suggesting that the impact of afforestation on Chernozem soils should be further investigated. The Kamennaya Steppe site (arable land surrounded by shelterbelt forests) is a reference site for monitoring studies at the Voronezh Carbon Test Site, where the carbon balance of agro-ecosystems is being studied and the ecological role of shel

The goal was to conduct an environmental assessment of chromium and nickel content in agroecosystems of the southwestern part of the Central Chernozem region using the example of the Belgorod region. All analytical studies were carried out in an accredited testing laboratory using generally accepted methods. During the research, it was found that the average gross content of chromium and nickel in the arable layer in leached chernozems is 19.8 and 24.5, in typical chernozems – 20.0 and 24.9, in or

The study aimed to identify the impact of shelterbelts on cultivated soils at three key sites in the forest-steppe zone of the southern part of the Central Russian Uplands. Automorphic chernozems were studied under 30 m wide longitudinally oriented broad-leaved shelterbelts; their plowed analogues – near the shelterbelts. The research was carried out in the area with heavy loamy and clayey typical chernozems.

The article presents the results of a comparative assessment of zonal soil conservation and zero tillage systems in the conditions of the moderately arid steppe of Northern Kazakhstan, on ordinary heavy loamy chernozome. As a result of the research, it was found that zero technology is not inferior in productivity to zonal soil protection technology. Under these soil and climatic conditions, an important criterion for choosing technology is the volumetric mass of the soil.

Timothy grass began to be used as a fodder crop in the north of the Non-Chernozem zone of Russia more than 400 years ago, most often it was sown together with meadow clover. These two species have quite similar biorhythms of development. Then this culture began to spread widely, first in Europe, and then around the world. The main advantages of Timothy grass are high ecological plasticity, good adaptability to heavy soils, and longevity. Modern varieties are characterized by good resistance to diseases, adverse weather conditions and relatively good quality indicators of the resulting feed.
