“…In world agriculture today, a large number of agricultural lands are unclaimed and are becoming unused (Borisenko, 2014;Rylov and Bayunov, 2019;Yin et al, 2019;Palšová et al, 2019;Nakvasina et al, 2019;Babajanov and Inamov, 2020;Bochkarev et al, 2020;Merzlova, 2020;Shevchenko et al, 2020;Vdovenko et al, 2020;Chupina et al, 2020;Buletsa, 2020;Prishchepov, 2020;Xie et al, 2020).…”

Currently, in modern world science, a large experimental material has been accumulated to search for new forms of nitrogen nutrition of plants and increase the use of nitrogen fertilizers to obtain sustainable crop yields, which is relevant in modern conditions. A science-based fertilizer system should ensure not only the production of planned crops at the lowest cost per unit of production, but also a systematic increase in soil fertility. The purpose of the study was to scientifically substantiate, develop and introduce into the production of agricultural techniques to increase the yield of grain and leguminous crops cultivated on irrigated lands of the North-Western Caspian Sea, which dropped out of active agricultural turnover. The field study was developed on the basis of existing zonal recommendations, complementing them with options for studied agro-receptions. Laying and conducting multifactorial field experiments in various edaphic conditions by the method of split divides was carried out in accordance with the method of B.A. Dospekhov, Fundamentals of Scientific Research in Agronomy. In order to increase the productivity of irrigated land removed from active agricultural turnover, an environmentally sound land use orientation should be envisaged, while maintaining high agricultural productivity.

The research conducted within the framework of the grant of the Ministry of Agriculture of the Russian Federation on the topic "Research of ownerless reclaimed lands in the Irkutsk region" in 2022 revealed long unused ownerless reclaimed agricultural lands related to pastures and hayfields. On the lands there are long time non-functioning hydro-reclamation drainage systems with destroyed open regulating and conducting network of canals. The surveyed agricultural lands are classified as overwatered. The lands mainly have favorable soil characteristics. Problems of using reclaimed lands have been identified. Recommendations on their further use for involvement into agricultural turnover are given.

Biogenic pollution of water bodies and their eutrophication is one of the most serious environmental problems of our time. One of the sources of water pollution with biogenic substances is forests, which belong to the background sources of biogenic load. Currently available methods for assessing the removal of nutrients from the forest vegetation cover do not provide the desired results, which causes an urgent need for their improvement. This article describes the method developed by the authors of geoinformation modeling of removal of biogenic substances from the forest vegetation cover to water bodies, taking into account the spatial distribution of vegetation in the catchment area, its species composition and absorption of biogenic substances during their migration. The Eastern part of the Gulf of Finland was adopted as the object of testing of the developed method. this is due to the fact that eutrophication processes are actively manifested within its water area. The volume of the background biogenic load on the Gulf of Finland, formed during the decomposition of the fall of the natural vegetation cover in the catchment area, was determined based on the specific removal of biogenic substances from plant communities and their absorption during migration “plant community — water object”. The total background biogenic load on the eastern part of the Gulf of Finland, formed as a result of decomposition of natural vegetation cover, was 170.21 t/year for the northern catchment for nitrogen, 12.14 t/year for phosphorus, and 207.31 t/year for the southern catchment for nitrogen , and 15.68 t/year for phosphorus. The data obtained do not contradict the results of other authors who study the background biogenic load on the Gulf of Finland. The method can be effectively used in the development of measures to reduce the nutrient load on water bodies and planning of economic activities in catchments.
