The article presents the results of the development of an information-measuring system for monitoring the sanitary status of tree stands. The main purpose of such a system is to minimize the impact of the operator on the results of monitoring the sanitary status of tree stands by indirectly controlling the quality characteristics of the tree sap (by establishing the dependence of these characteristics on climatic factors) with the possibility of remote monitoring and control of the process of express control. The developed monitoring system allows to conduct a contactless (remote) survey of sensors, which are recorded in close proximity to the root system of selective trees from an array of tree plantations, and further, by mathematical treatment of climatic characteristics (acidity and salinity index, air temperature) zoning temperature health status. The system also allows you to predict the dynamics of extending the areas of tree planting. This enables those responsible for tree planting to take preventative measures to prevent such droughts. The main advantage of the developed information measurement system is its complete computerization, which eliminates a number of external subjective influences by the operator or the responsible person (necessity of visual inspection of the maximum number of trees in the array, erroneous perception of visual information, etc.). This, in turn, avoids systematic methodological errors, thereby improving the accuracy, speed and reliability of the monitoring and control results of this system.
