The study of ecosystems, biological and ecological features of perennial grasses, soils, groundwater and monitoring of their dynamics are impossible without lysimetric studies. Lysimeters serve as a reliable means of studying and managing agroecosystems and the entire complex of plant development factors. At the All-Union Williams feed research Institute, lysimetric studies on the study, regulation and forecasting of water, food and thermal regimes of reclaimed natural forage lands in the agroecosystem "soil — plant — infiltration runoff" on irrigated pastures in the conditions of the Central District of the Non-Chernozem zone (Moscow region) were started at the Lysimetric Station built in 1972. The station includes a laboratory building, a tunnel room with a depth of about 3 m and a length of more than 40 m, a hardware room, lysimetric devices and installations of a special design. The lysimetric installation allows you to jointly study the water balance, the balance of chemicals and automate the observation processes. The developed design of the measuring equipment increased the accuracy of the experiment, and due to its small dimensions, it allowed experiments to significantly expand the range of studied groundwater depths (from 0.75 m to 2 m). Lysimeters of 2 types (for water balance and agrochemical studies) are designed for year-round observations. The results of lysimetric studies are extrapolated to areas with similar environmental conditions.
