Abstract: A topical issue in the harvesting of forage grasses is to preserve the nutrients in the harvested forage and reduce the cost of its production. An efficient means to solve this problem is provided by the processes of electrotechnology, where the working body is strong electrical fields. In such electrotechnological processes as electro-osmosis and electroplasmolysis, the plant material is an element of an electrical circuit, in which the electrophysical properties of the processed object can be reasonably simulated by an electrical equivalent substitution circuit. The elements and configuration of the substitution circuit and the main directions of increasing the energy efficiency of the electrotechnological processes can be substituted via analysis of the physical processes in the stem wall of forage grasses. The goal of this study was to establish the analytical relationship between the rate of moisture and electrical current transfer through the stem wall of plant tissue for implementation in electrotechnological processes in agriculture applications. The object of study is the stem wall of forage grasses (Bromus inermis). The main provisions from the theory of electrotechnology, biophysics, electrochemical kinetics, ion exchange, and electrochemical alternating current circuits are used. The mathematical model establishes the relationship between the process of moisture transport through the plant tissue in the transverse direction under the influence of electrical current. The stages of current and moisture transfer through the stem wall are considered by using a stem wall selected arbitrarily from a grass mass as an example with consideration for the adopted assumptions and the presumed distribution of electrical potentials at the phase interface. The role and place of the technological component of the current through the plant tissue wall are established. The set of derived equations describing the process of moisture transfer through the plant tissue in the transverse direction under the influence of electrical current determines the prerequisites for the synthesis of a substitution circuit. The ways of increasing the technological component of the current are determined. Improving the efficiency of electrotechnological processes in the processing of plant materials (in particular, electroosmotic dehydration) should be considered as a process of increasing the share of the technological component of "direct" current in the total current and decreasing its thermal effect.
