“…These characteristics depend on the structure, the ratio of para-, dia-, ferromagnetic components, mineral and chemical composition of the soil. The magnetic properties of the rock must be taken into account because of its effect on the deposition of rocks, the formation of structure and texture, and the mechanical properties of suspensions and sediments [33][34][35][36][37].…”

According to the information contained in the works of some research groups, magnetic soil cultivation can be used to protect crops from frost [49][50][51], however, the results obtained on the basis of assessing the germination of biotest objects in previously moistened soil make us look at this fact in a comprehensive manner, namely: while changing the freezing temperature of the soil, a magnetic field, especially quasi-stationary, can significantly reduce the germination and slow down plant growth.…”

The article presents the results of studies that allow us to assess the environmental impact of various types of electromagnetic fields on the effectiveness of subsequent remediation measures and the inclusion of areas that have been exposed to electromagnetic effects in residential areas, as well as the use of agricultural land. The growth dynamics of biotest objects of vegetation planted in technogenic soil that has undergone preliminary treatment with electromagnetic fields of various nature was evaluated. An assessment was also made of the effect of magnetization on the structure of the soil and its filtration ability, including the change in the state of soil layers caused by the action of electromagnetic fields on inherent moisture. As a result of the research, data were obtained that make it possible to assess the degree of influence of electromagnetic fields of various kinds on the effectiveness of subsequent reclamation measures and the use of the inclusion of zones exposed to electromagnetic effects in the composition of residential areas, as well as for agricultural land. Thus, plants planted in technogenic soil, previously subjected to electromagnetic influence, demonstrate a pronounced inhibition of ontogenesis, this effect is enhanced if the soil was previously in a moist state. It was found that the introduction of fertilizers into the soil, previously subjected to electromagnetic action, has a beneficial effect on plant growth, but their effectiveness is significantly reduced.

“…The MS was assessed with a KT-10, that measures the susceptibility that a given sample has to be magnetized by induction (Figure 1d), which depends on its composition and is mainly associated to the Fe and clay contents (Kanu et al, 2019). The "zero" susceptibility was registered in the air.…”

“…This is a powerful tool based on specific electronic transitions induced by an X-ray source and can be used even on field measurements (portable XRF) (Stockmann et al, 2016). The magnetic susceptibility can provide information about the soil mineralogy, texture and other soil attributes (Fine et al, 1992;Camargo et al, 2016;Asgaria et al, 2018;Kanu). This property is important on the study of soil parent materials and is associated mainly to pedogenetic formation of ferrimagnetic minerals as the maghemite (Asgaria et al, 2018).…”

Proximal and remote sensing on the soil processes: from punctual to spatial approaches

Soil layers and horizons have been described in the field by Pedologists who have enough knowledge about a given region. Although limited alternatives have been used to describe the soil by equipments under natural conditions. Therefore, we must expend efforts on applying the newest technologies on these studies. We have proposed to use Vis-NIR and X-Ray Fluorescence (portable) equipments to predict soil horizonation and its process. The main objectives were: i) Identify mineralogical differences between horizons, with inferences about translocations and geochemical alteration by proximal sensors; and ii) Expand the punctual information with RGB images and Digital Surface Model obtained by unmanned aerial vehicle. Seven soil profiles (Acrisol, Cambisol and five Ferralsols) were analyzed in a São Paulo, Brazil region. The data were vertically collected in the field with a Vis-NIR-SWIR (350 -2,500 nm) spectroradiometer and with a Portable X-ray Fluorescence (pXRF). Dried samples from each layer were analyzed by a Middle Infrared (MIR) (2,500 -20,000 nm). When with exposed soils, images were taken by UAV and Terrain derivatives were built by stereoscopy. Proximal sensors allowed to perform more robust hypothesis about soil formation processes. On-the-go proximal sensor allows to describe and better understand how soil bodies behave on the landscape. The clusterization with high density data from sensors allows to better describe soil profiles horizonation. The Vis-NIR-SWIR spectral range relationship together with soil color, provides better correspondence with traditional field observation. The combined use of Vis-NIR-SWIR, MIR and pXRF allows to identify the horizon boundaries more appropriately. There was a limit between the surface color of each profile and relief which took an important spatialization by UAV data. From profiles to spatial dimension, relief plus RGB of UAV indicated important delineation of soil units.
