Purpose: to assess the drainage runoff potential in Russia for humidification purposes using drainage-watering systems. Materials and methods. The informational basis of the research was made up of information received from federal state budgetary institutions on land reclamation and agricultural water supply, in the context of the diverted drainage runoff volume from drainage, drainage-watering and drainage-irrigation systems of double soil water regime control as well as data from annual monitoring. The following software products Microsoft Excel, ArcGIS, MathCAD were used to process the data on drainage runoff indicators. General scientific methods were used to analyze the data obtained on drainage runoff volume and graphic material. Results. When quantifying the drainage runoff volume and its mineralization, complications associated with a shortage, and in some cases with a lack of data on drainage runoff from reclamation systems arose. Based on the data received, 22 regions with operating drainage reclamation systems were identified. For each reclamation system, the drainage runoff volume and the total area of drained lands were determined. The regions with the largest, sufficient and insignificant volumes runoff have been identified. For some regions, data on the salinity of the drainage runoff were obtained and analyzed. Conclusions. As a result of analysis it was revealed that almost 50 % of the territories served by drainage systems can be moistened with drainage runoff in full volume of all serviced areas with accumulation in regulating tanks; in the rest of the regions additional water withdrawal from the water source is required. Indicators of drainage runoff salinity are 0.22–1.60 g/l, in some systems they reach 2.1–4.7 g/l, which indicates the possibility of using agricultural crops in irrigation on various types of soils and for fish farming.

The article considers the issue of assessing the long-term results of work on fisheries reclamation in inland waters of fisheries significance in Russia, carried out by the branches of the Federal State Budgetary Institution “Glavrybvod” on the state task in terms of their effectiveness. The relationship between dredging and clearing of watercourse beds and the dynamics of the number of producers of semi-navigable and non-aquatic fish in these rivers during spawning migrations has not been established. With long-term mowing of wetland vegetation in the shallow waters of reservoirs, deltas of large rivers and estuaries, there is no increase in their commercial fish productivity. A number of examples show the opposite effect of this type of work, which leads to a local deterioration of the ecological state of these reservoirs. At the same time, the repeatedly proven method of combating higher aquatic vegetation in the reservoirs of the south of Russia in low water conditions as biomelioration, based on the introduction of fish, consumers of autotrophic products by regional branches of the Federal State Budgetary Institution “Glavrybvod” is practically not used. When installing artificial spawning grounds in the littoral zone of reservoirs, regular ichthyological monitoring of the effectiveness of spawning on them is not carried out. There are no reliable data confirming the significant positive impact of artificial spawning grounds on the population dynamics of commercial fish species of the limnophilic ecological group under conditions of significant spring water level depletion in Russian reservoirs. When catching predatory and low-value fish species in water bodies, legal obstacles arise due to the fact that the volume of seizure of predatory fish includes commercial objects for which the ODE is established annually and their catch is already carried out according to industrial quotas.

In the Omsk region in the 60s of the last century, the problems of providing animals with feeds led to large-scale work to strengthen the material and technical base of the reclamation complex. Over 20 years (1970 to 1990), the area of irrigated land increased from 4 to 115 thousand ha. According to the data of the Federal State Budgetary Institution Management Omskmeliovodkhoz in the Omsk Region as of December 31, 2017, arable lands are considered irrigated – 78864 hectares, while no more than 8 thousand hectares are actually irrigated. Almost 33 thousand hectares of this area cannot be restored for various reasons, and overhaul is required on an area of more than 34 thousand hectares. The reclamation industry is being restored thanks to the targeted subprogram «Development of Land Reclamation for Agricultural Land». This requires the coordinated work of the Ministry of Agriculture and Food of the Omsk Region, agricultural producers and the Federal State Budgetary Institution «Management» Omskmeliovodkhoz «with scientific support for the industry. This requires the coordinated work of the Ministry of Agriculture and Food of the Omsk Region, agricultural producers and the Federal State Budgetary Institution «Management «Omskmeliovodkhoz» with scientific support for the industry.

The article discusses the results of long-term field research on irrigation of perennial grasses with livestock runoff. The aim of the research was the experimental justification of land reclamation measures and drainage-free run off during irrigation of land with runoff from pig-breeding complexes. Experimental studies were conducted on a specialized reclamation system in Orsha district of Vitebsk region, where the soil cover is represented by sod-podzolic loamy soils. The experimental design included 8 options. As a result of research, it was found out that irrigation with livestock runoff leads to compaction of the upper soil layers. In the arable layer of 0–20 cm, the additional density increased from 1.26 to 1, 32 g/cm3, or 4.8 %, compared to the control, and in variants with irrigation and drainage measures, the compaction was somewhat less. In the soil layer of 0–40 cm, deconsolidation was greater only in the variants with soil deepening and loosening by 4 %, and when applying straw – by 5.1 %.In the 0–60 cm layer, a decrease in the density of addition was observed only in the variants with deep loosening and the introduction of straw. It was also found out that soil water loss varies over time. It is most intense in the first 2–3 hours and almost completely stops after 10–18 hours for monoliths with a thickness of 0.4–0.6 m, and in monoliths of 1.0 m, after 36–48 hours. The highest intensity of water loss was registered in options 5, 6 and 7. The lowest was in the control variant and option 2, where no land reclamation measures were taken. In options 5, 6 and 7, a decrease in the intensity of water loss by years was noted. Thus, in option 5 in 2000, water loss amounted to 0.9 mm /h, in 2001 – 0.87 mm/h, and in 2002 – 0.85 mm/h. Similar patterns were revealed in options 6 and 7. In the control option and option 2 without agro-reclamation measures, the intensity of water loss also decreased. The decrease in the intensity of water loss over the years is associated with changes in the density of the soil caused by anthropogenic impact on it. First of all, with compaction by farm machines and ongoing irrigation of perennial grasses.
