On August 27, 2024, a delegation of the leading domestic developers visited the KubSAU’s Nanobiotechnology Center to demonstrate new radiophysical equipment - LET and Planar. The guests have demonstrated the operation of a recently developed unique domestic radio measuring complex for determining the dielectric properties of sheet materials. The complex includes a vector circuit analyzer of the Cobalt C2220 series and a SPLIT-1 slot resonator. This equipment is actively used in classical radiophysical applications and been first used in the agro-technological field. The new instrument complex, using digital methods for vector analysis of microwave electric circuits created by domestic developers, allows determining the proportions of "bound" and "free" water in the tissues of tree leaves and fruit and vegetable crops in the natural environment in a short time (up to 10-15 seconds). This is necessary to assess the quality of water exchange in agricultural crops. This is very important in practice for studying the physiology of water exchange in the issue of drought resistance of plants in the Krasnodar Territory. Thus, in ecological and physiological studies of cultivated plants, the key indicator for characterizing the water regime of plants is the water content in their leaves. Changes in the ratio between the “free” and “bound” forms of water in plant leaves indicate the nature of the changes occurring in the protoplasm, the intensity of the processes of mineral salt consumption and indicating the degree of adaptability of this plant to surviving water deficiency in changing climate conditions, – said Igor Sukhno, Head of the Center for Nanobiotechnology at KubSAU. The demonstrated capabilities of the new domestic radio measuring complex for determining the dielectric properties of plant leaves open up broad prospects for conducting laboratory and field research in the field of physiology of water exchange in plants and the development of methods for economical targeted irrigation of fruit trees in the developing concept of “digital farming”. In the near future, the parties plan to continue joint scientific and practical research within the framework of the federal grant.
