“…For example, in the steppe zone during the Holocene, human economic activity and climate change led to the activation of the solonetz process and the general degradation of the soil cover up to erosion as a result of which the upper soil horizons were destroyed. [7]. This led to the loss of chemical elements associated with the humus horizon of the soil (Fe, Al, K, Mn, P, Ti, Zn, V, Cr, Rb, Zr), and an increase in the concentration of elements associated with the underlying carbonate and gypsum horizons (Ca, Na, Mg, P, S, Sr) (Table 1) [8].…”

The cultural layer (CL) is a layer of soil at the sites of human settlements that contains traces or remnants of human activity. From the point of view of geochemistry, the CL is a complex object of study. For a long time, impurities that are not characteristic of the natural soil come to be here, such as hair, nails, ceramics, ash, leather, fabric, wool, bones, manure, straw, coal, and food. The penetration of these objects into the soil leads to an increase in the content of biogenic elements: nitrogen, carbon, phosphorus, sulfur, calcium, iron, and a decrease in the proportion of elements, which mainly consists of the mineral matrix of the soil: silicon, aluminum, and potassium. As a result, the CL acquires properties different from those of the soil. It increases the weight loss on ignition and decreases the proportion of the solid phase, which creates significant difficulties for X-ray fluorescence analysis.

“…It is noteworthy that in the B2 horizon the content of mobile sulphur remains very high, while in the parent rock it decreases by 2 times compared to the solonetz horizon and by 3 times compared to the solonetz horizon. Consequently, in the initial stage of soil evolution there was purely chemical weathering of pyrite [8] to iron sulphate and eventually, judging by the colour, to limonite. The sulphuric acid produced in the reaction reacts with the carbonate group minerals with the accumulation of readily soluble sulphates.…”

The main objective of the work was to identify the evolutionary changes in the profile of recent and buried soil in the Holocene, the content of humus and the composition of mobile forms of nutrients in the solonetzol- silted black soil in the insufficiently wetted zone of Stavropol Krai. The research was carried out near the village of Inozemtsevo, Stavropol Krai. The soils of the study area are formed on marine sediments. A 1.5-metre-high grave was erected more than 5,000 years ago. At a distance of 150 metres, an incision was made on recent virgin soils. According to morphological characteristics, recent soils are medium saline fused medium powered black soils, while the buried soils evolved into weakly saline fused low powered black soils. They are distinguished by lower profile thickness and brown, rather than black, colouring. There is a BC horizon in recent soils, which is absent in paleosoils. New formation of carbonates and gypsum is noted only in recent soils in B2 and BC horizons. The organic matter content in recent soils is 5-6% and decreases 6-7 times in paleosoils in the upper horizons. Recent soils are depleted in mobile phosphorus, but enriched in mobile potassium. Differences in the content of mobile sulphur are due to some salinity of the paleosoils. In the content of mobile trace elements, the differences between the studied soils are significant, especially zinc, cobalt and molybdenum. Consequently, during the evolutionary period of 5 thousand years, the soil-absorbing complex was impoverished by these microelements.

“…В силу небольшого уровня накопления биомассы степные ландшафты по уровню самоорганизации и устойчивости уступают многим другим природным зонам, что при изменении климата может привести к нарушению и достаточно трудному восстановлению их стационарного состояния [1]. Отмечают, что почвы степей представляют собой довольно консервативные образования и в течение голоцена климатические изменения не приводили напрямую к смене их типов [3]. В то же время выявлено, что произошло значительное изменение флористического разнообразия растительности евразийских степей, которое чаще всего уменьшается со снижением влагообеспеченности [4].…”

В этом исследовании была оценена взаимосвязь между реакцией растительности на аридизацию климата и ее влияние на геохимические свойства почв, что имеет большое значение для понимания устойчивости степных ландшафтов при дальнейших тенденциях к потеплению климата. В результате исследования показано влияние климатических факторов на свойства растительных сообществ и их влияние на скорость возврата химических элементов в верхние горизонты почвы. Так же изучен химический состав каштановых и бурых полупустынных почв и оценен эффект от изменения растительного покрова на вариативность их геохимических параметров. Показано, что аридизация климата приводит не только к уменьшению продуктивности ландшафтов и развития таких дегазационных процессов, как эрозия и опустынивание, но и к смене их биогеохимических свойств.
