“…• in the absence of actions on the part of farmers, humai and pigs will cover the ground with a dense "carpet", closing the rest of the plantings. Analysis of theoretical and experimental studies on the application of electrical action on living organisms and plant tissues [4][5][6][7][8][9][10][11][12][13][14][15], as well as discharges of electric current pulses for processing CMC based on the technology proposed by us, made it possible to formulate the requirements for the design of a mobile setup and electrodes, forming sown areas, which are as follows:…”

“…Along with changes in the electrical potential observed in the stimulation zone, water and salt stress induce propagating root-to-shoot signals, including hydraulic signals, ROS and Ca 2+ waves, and electrical signals [ 3 , 155 ]. In particular, drought induces the VP propagation to the shoot of Vitis vinifera [ 175 ]; and a wave of depolarization that propagates along the phloem in Zea mays [ 176 ]; irrigation after drought induces the AP propagation in the phloem [ 176 , 177 ].…”

“…The mechanisms of the specificity of VPs in plants have to be elucidated in future studies, but they can be hypothesized, based on the mechanisms of propagation of this distant stress signal. VP propagation is quite complex, due to VPs being composite signals of cross-interacting electric, hydraulic and chemical waves [ 3 , 6 , 17 , 175 ]. A hydraulic wave can act as a trigger for electrical changes during VP propagation, which is convincingly evidenced by VP induction using an artificial increase in pressure [ 190 , 255 ].…”

Plants have developed complex systems of perception and signaling to adapt to changing environmental conditions. Electrical signaling is one of the most promising candidates for the regulatory mechanisms of the systemic functional response under the local action of various stimuli. Long-distance electrical signals of plants, such as action potential (AP), variation potential (VP), and systemic potential (SP), show specificities to types of inducing stimuli. The systemic response induced by a long-distance electrical signal, representing a change in the activity of a complex of molecular-physiological processes, includes a nonspecific component and a stimulus-specific component. This review discusses possible mechanisms for transmitting information about the nature of the stimulus and the formation of a specific systemic response with the participation of electrical signals induced by various abiotic factors.

“…Multivariate analyses and other statistical methods have been widely applied in studies to determine the sources of elements found in soil, such as total soil salt content and heavy metals [16] – [18] . The spatial variation model and spatial distribution are used to make a hazard risk map of soil salt properties in regions of interest.…”

In order to evaluate the soil salinization risk of the oases in arid land of northwest China, we chose a typical oasis-the Yanqi basin as the research area. Then, we collected soil samples from the area and made comprehensive assessment for soil salinization risk in this area. The result showed that: (1) In all soil samples, high variation was found for the amount of Ca2+ and K+, while the other soil salt properties had moderate levels of variation. (2) The land use types and the soil parent material had a significant influence on the amount of salt ions within the soil. (3) Principle component (PC) analysis determined that all the salt ion values, potential of hydrogen (pHs) and ECs fell into four PCs. Among them, PC1 (C1-, Na+, SO4 2-, EC, and pH) and PC2 (Ca2+, K+, Mg2+and total amount of salts) are considered to be mainly influenced by artificial sources, while PC3 and PC4 (CO3 - and HCO3 2-) are mainly influenced by natural sources. (4) From a geo-statistical point of view, it was ascertained that the pH and soil salt ions, such as Ca2+, Mg2+ and HCO3 -, had a strong spatial dependency. Meanwhile, Na+ and Cl- had only a weak spatial dependency in the soil. (5) Soil salinization indicators suggested that the entire area had a low risk of soil salinization, where the risk was mainly due to anthropogenic activities and climate variation. This study can be considered an early warning of soil salinization and alkalization in the Yanqi basin. It can also provide a reference for environmental protection policies and rational utilization of land resources in the arid region of Xinjiang, northwest China, as well as for other oases of arid regions in the world.
