The paper considers the urgent problem of increasing the efficiency and accuracy of field research of soil tillage units in the Strip-Till technology. Modern requirements of intensive farming involve optimizing energy costs and ensuring the stability of technological processes, which necessitates the creation of specialized control and measuring systems. An analysis of recent studies and publications has been conducted, which consider various designs of units and systems for automatic adjustment of the depth of cultivation, and their advantages and disadvantages have been identified. In particular, the complexity of multi-component systems and the limited ability to adjust in a wide range have been noted.

Within the framework of the paper, a design of a cultivator section for strip tillage is proposed, equipped with strain gauge sensors for determining traction resistance. A measuring system based on an analog-to-digital converter mDAQ-12 and a microprocessor platform has been developed, which provides registration, storage and processing of data in real time. The sensors were calibrated using crane scales, calibration characteristics were constructed and the results were approximated, where the cubic dependence was found to be the most adequate.

Field tests were carried out using the FENDT 900 Vario tractor. The results obtained showed the correspondence of the experimental data to the mathematical modeling with a discrepancy of no more than 8%. This confirms the operability of the proposed system and its ability to provide reliable control of traction resistance, which allows determining the optimal design and operational parameters of the unit. The use of the system contributes to minimizing fuel consumption, increasing the accuracy of research and forming substantiated recommendations for improving soil tillage machines.

Thus, the developed control and measuring system is an important scientific and practical solution for increasing the efficiency of Strip-Till technologies and ensuring energy saving in modern agriculture.
