Abstract
The article provides information about the possibility of monitoring the reclamation situation of agricultural land by studying the soil-lithological profile by means of electrometric methods. The essence of the applied resistance method is the study of the soil layer using constant or variable electric fields. For engineering geophysical works in sand-clay sections typical of the Stavropol Territory, various variants of research technologies are presented. The conducted studies have shown the effectiveness of the electrometric method of vertical electrical sounding, which allows, based on surface observations with a minimum amount of control drilling and analytical work, to obtain operational information about changes in the area and depth of such an important parameter for assessing the reclamation state of soils as their specific electrical resistance, depending on humidity and salinity. The VEZ method, in addition to the available information about waterlogged and saline wetlands observed on the earth’s surface by traditional methods, allows us to obtain information about hidden unfavorable zones: about changes in their configuration in area and depth.
Highlights
IntroductionThe main condition for the favorable reclamation situation is that the mineralized ground water does not have its depressing effect on the root system of plants
The main indicator of the reclamation situation that affects the soil-forming processes of artificially irrigated lands is the level of ground water, or rather the depth of its occurrence.The main condition for the favorable reclamation situation is that the mineralized ground water does not have its depressing effect on the root system of plants
The soil layer consists of an aquifer and an aeration zone; in turn, each of them is divided into separate parts in accordance with the formed value of the gradient of the soil moisture ratio to the depth of the ground water level (UGV)
Summary
The main condition for the favorable reclamation situation is that the mineralized ground water does not have its depressing effect on the root system of plants. This condition is met if the capillary rim does not reach the root layer during its upward movement from the aquifer, i.e. it does not come into contact with it. The soil layer consists of an aquifer and an aeration zone; in turn, each of them is divided into separate parts in accordance with the formed value of the gradient of the soil moisture ratio to the depth of the ground water level (UGV). The minimum on the moisture curve, marked in the roof of the capillary border, determines the thickness of the supracapillary-border thickness-– NHKK. It should be noted that in our example, there is no mineralized ground water
