Abstract:

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

Abstract:

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

Abstract:

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

Abstract:

Sea buckthorn cultivation in the Republic of Moldova represents a young but profitable branch with development perspectives due to the nutritional value of the products, to the protection qualities of eroded soils and to the accumulation of biosynthesized nitrogen in the soil by the plant root system. The current sea buckthorn plantations in the Republic of Moldova occupy a very wide spectrum of soils and their textural varieties, from typical chernozems in Balti steppe (Sangerei district - Dobrogea Veche), to the gray and brown forest soils in the Central Moldavian Plateau - Codrilor Plateau

Abstract:

One of the most justified and applied approaches to isolating pools of soil organic matter is fractionation in heavy liquids. The main problem with this approach is rather large losses in the separation of fractions at the stage of washing fractions from heavy liquids. The paper presents a densimetric fractionation protocol that can significantly reduce these losses. It is suggested to use 0.001 M HCl for washing. This approach, in comparison with distilled water, allows reducing losses of weight from 15 to 5% and of carbon from 7.5 to 2.5%. The paper provides a detailed protocol, used by the
