A large-scale analysis of the condition of melioration systems of Belarus was carried out taking into account the terms of their operation. Dependencies of the deterioration of the melioration condition on the time elapsed after the commissioning of the facility were established. The proposals were made for conducting a cadastral assessment of meliorated objects.

In Russia, drip irrigation is considered the most watersaving and environmentally friend-ly method of irrigation, and the most automated in its technical implementation. For industrial production, drip irrigation tapes and tubes are produced in the amount of about 1 billion linear meters per year. The characteristics of the tubes allow you to select the necessary irrigation pa-rameters for any crop and soil characteristics. With the modern requirement for saving water and energy resources, preserving and increasing soil fertility, protecting plants and agrolandscapes in general have been confirmed specifically when growing plants "Patriarch's Garden" in the central part of the city of Vladimir. On the slopes of the ravine, terraces are created in difficult terrain conditions, where the entire irrigation complex of the agro-landscape is located for watering flower plants, apple trees, cherries, etc. It provides moisture and creates conditions for people to relax, delighting with its design.

The article presents new designs of drainage and cleaning elements with filtration filing of suspended containers (containers) at the end of the drain. The effectiveness of their work on removing contamination of mineralized drainage and waste waters is shown, which will ensure a significant improvement in water discharge and its reuse for irrigation.

Conducting surveys of hydraulic structures is a basic determining nature for assessing: the technical condition and safety of hydraulic structures (HS) and their complexes, forecasting their changes over time; the adequacy of measures taken (or being taken) by the owner of the structure to prevent emergency situations; compliance by the operating organization of the rules, instructions and other regulatory documents on the technical operation of the HS; the possibility of their further trouble-free operation or the need for restoration and strengthening. Such measures are the basis for developing recommendations for improving the safety of HS and an inalienable part in the design of their major repairs or reconstruction. The article presents the provisions of the methodology for surveys of HS of hydro-engineering facilities in operation, which increase the efficiency and reliability of their operation.

A study of the water permeability of sod-podzolic light loamy soils and the formation of surface runoff during sprinkling in the conditions of eastern Belarus was shown that the amount of surface runoff is directly dependent on the intensity of rain, the irrigation rate, and the slope of the plot, and is inversely proportional to the development of the leaf surface of Sudan grass. A design of a finemist sprinkler nozzle with two reflective discs has been developed to optimize the size of droplets and reduce the risk of erosion. An empirical equation has been obtained for calculating the rain capture radius depending on the pressure and nozzle diameter. The results of the study allow us to recommend the use of low-intensity sprinkling systems and irrigation during the development phase of crops with sufficiently developed leaf surfaces to minimize surface runoff.

This article examines the practice of using artificial intelligence (AI) as a fundamental element of the smart agriculture paradigm. Studying the experience of implementing AI in agriculture in different countries allows us to identify the advantages of AI, identify the factors constraining the development of AI in agriculture and the most effective ways of its further development. The use of AI in agriculture involves the integration of innovative solutions, including machine learning, computer vision, robotics and the Internet of Things (IoT), in order to modernize agricultural work. These tools allow farmers to accumulate and process information, automate routine operations and make reasonable decisions, which in turn helps to increase productivity and optimize the use of resources. This article summarizes the global experience of applying innovative methods and technologies using AI in agriculture.

When forecasting crop yields, it is necessary to take into account the complex of soil and hydrological conditions of individual areas and the provision of agricultural producers with chemicals. Information and reference decision support system for arable and meadow agrophytocenoses on reclaimed mineral and peat lands allows, based on the balance of nutrients in the “soil-plant” system, to calculate the expected yield of agricultural crops(winter rye, wheat, triticale and spring crops ‒ barley, wheat, triticale, alfalfa, hay) on reclaimed lands, taking into account possible losses due to violation of the water regime with an accuracy of 1.5‒14,8 %.
