The aim of the work is to establish the relationship between the composition of soil air and soil fertility indicators, which will be the basis for creating a method for determining their quality. The report focuses on the relationship between soil type, soil quality and soil air composition. Emphasis is placed on the use of sensor sensors as a promising direction in the development of soil agricultural technologies. The relevance of remote monitoring of soils and soil air in real time using the e-nose system is indicated. A remote monitoring system is proposed using existing commercial sensors to detect CO2, O2, NOx, CH4, CO, H2 and NH3, which can be moved by a quadcopter, which can allow parallel scanning of soils and land. The effect of yttrium (III) oxide modifier on the electrical properties of the stanum (IV) oxide (synthesized by the CVD method) in the atmosphere of air, carbon dioxide and acetone has been studied. The sensitivity of modified and unmodified samples in the medium of these gases is calculated. The influence of the ZnO modifier in TiO2/ZnO nanocomposites synthesized on the basis of the commercial product TiO2/P90 by the impregnation method on the adsorption-structural, photocatalytic and electrical properties of the nanocomposite was revealed. TiO2/ZnO systems are characterized by XRD, X-ray fluorescence, XPS and low-temperature nitrogen adsorption-desorption. Within this stage of the project, sensors were purchased and adjusted to determine the composition of the gas phase of soils, namely the content of CO2, NO2, oxygen, etc.; synthesis and modification of 1D-nanostructures of stanum (IV) oxide (IV), and titanium (IV) oxide were carried out and studied as sensitive layers of future sensory elements.
