Spatiotemporal Dynamics of Soil Penetration Resistance of Recultivated Soil

Abstract

Zadorozhnaya G.: Spatiotemporal dynamics of soil penetration resistance of recultivated soil.This article examines changes in the spatial distribution of soil penetration resistance in ordinary chernozem (Calcic Chernozem) and in the recultivated soil in 2012 and 2014. The measurements were carried out in the field using an Eijkelkamp penetrometer on a regular grid. The depth of measurement was 50 cm, the interval was 5 cm. The indices of variation of soil penetration resistance in space and time have been determined. The degree of spatial dependence of soil penetration resistance has been determined layer by layer. The nature of temporal dynamics of soil penetration resistance of chernozem and technical soil has been described. A significant positive relationship of the structure of chernozem in the two years of the research has been shown. Significant correlations between the data of different years in the technical soil were found to be mostly negative.

The Relationship Between Soil Heterogeneity and Cellulolytic Activity

“…These soil morphological structures extend beyond the genetic horizons' limits and extend to the entire thickness of the soil. Their distribution in space is consistent with changes in environmental conditions and the plant community structure Zadorozhnaya et al, 2018). New soil elements have been found in all types of natural and technogenic soils that we studied.…”

“…The soil penetration resistance was studied in the field environment to a depth of up to 50 at 5 cm intervals. A hand penetrometer Eijkelkamp was used in the study (Medvedev, 2009;Medina et al, 2012;Zhukov, Zadorozhnaya, 2016, 2017Zadorozhnaya, 2018). The average error of the measurement results of the device is ± 8%.…”

Diversity, dynamics and ecological analysis of flora of reclaimed soil

“…The transformation of the environment here is relatively slow, the habitat capacity is higher. In anthropogenic soil, soil formation processes proceed at an increased rate (Gerasimova et al, 2003;Zadorozhna, 2018). This is confirmed by accelerated changes in the species composition of the plant cover.…”

“…A complex generalized characteristic of environmental conditions can be obtained using the ecological characteristics of species of flora (Diduh, 2011; Andrusevich and Shtirts 2014). The course of ecosystem and soil formation is generally reflected in the dynamic rearrangement of the plant community (Zadorozhna, 2018;Zadorozhna et al, 2018.). Studies on this theme have great prospects for use because they are practical and relatively simple to carry out.…”

Potential Possibilities of Soil Mesofauna Usage for Biodiagnostics of Soil Contamination by Heavy Metals

“…The dependence of the decrease of the mesopedobionts' vitality index on the total indicator of soil contamination level indicates the presence of the stability in the groups of soil invertebrates. With increased level of pollution, the decrease in the vitality of mesopedobionts is inhibited, which can be explained by the activation of homeostatic mechanisms in the group (Zhukov, Shatalin, 2016;Zadorozhnaya, 2018).…”
