Associated data on the physicochemical properties of pedosediments, climatic and dendrochronological indicators for palaeogeographic reconstructions

Abstract

Palaeogeographic markers can be justified among a large number of geochemical indicators in separate layers of pedosediments. This determines the need to develop a system of most information-rich pedogenetic indicators for reconstruction of the dynamics of erosion-accumulative processes based on dated earthen defensive constructions of the historical period. We demonstrated this solution at the example of a frontier rampart with a ditch of the mid-17th century (“Catena linking of landscape-geochemical processes and reconstruction of pedosedimentogenesis: a case study of defensive constructions of the mid-17th century, South Russia” [1]). Using individual of macroelements and trace elements as part of complex geochemical relationships and indicators allows us to determine the geochemical associations of elements that diagnose migration of the sediments at the trans-eluvial catenas. It is shown that in the forest-steppe conditions the determined system of pedogenic indicators, such as content of particles (%) with the size >0.01 and < 0.005 mm, pHH2O, CO2, (CaО+MgO):Al2O3, Si:Al, CaO:TiO2, the eluviation coefficient, the association of mobile (Ca, Na, Mg, Sr) and weakly mobile (K, Ba, Rb) elements, the sum of the elements accumulated in the soil (P, Ca, K, Mg, Mn, Cu). They can be the basis of this classification and chronostratigraphy of pedosediments. The data obtained in these investigations are aimed at the establishment of soil-geomorphologic interrelations and calibration of mathematical models of natural processes.

Spatiotemporal patterns and vegetation forecasting of sunflower hybrids in soil and climatic conditions of the Ukrainian Steppe zone

“…Since the 2000s, the number of abnormal climatic conditions has tripled, which caused a rise in the average annual temperature by 2.6°C and a higher number of torrential precipitations in the spring-summer period (Pichura et al, 2022). This results in: a decreasing precipitation-productivity (Lisetskii et al, 2020;Oti et al, 2020), an increase in wind erosion (Dudiak et al, 2021), local torrential precipitations and water erosion processes (Özşahin, 2023), as well as higher risks of terrestrial runoff, disruption in transpiration and increased evaporation of moisture in the summer-autumn period, water deficiency for agrocenoses (Assan et al, 2020). Under such extreme climatic conditions, moisture is a limiting factor in the productivity of agricultural crops (Török et al, 2020), therefore the agrotechnological conservation of pre-sowing soil moisture and the effective use of its reserves during the vegetation period of plants are utterly important (Domaratskiy et al, 2020;.…”

Modeling of Trace Elements and Heavy Metals Content in the Steppe Soils of Ukraine

“…Manganese (Mn) is involved in the process of photosynthesis and synthesis of vitamin C, the content of which is an indicator of fruit quality. The Mn deficiency is most often observed in the soils with a neutral or alkaline pH, especially on sandy and loamy soils (Lisetskii et al, 2020a) Copper (Cu) promotes normal growth and development of the plant. With insufficient supply of Cu plants stop growing due to violation of the insemination process of cereals and fruit trees.…”
