Periodically recurring droughts, unstable atmospheric moisture, and elevated air temperatures in summer are characteristic of the Orenburg region, which is part of the South Ural region. Of great scientific and practical importance at the present stage is the creation of soils that are optimal in terms of physical and chemical composition, giving high production results. The article presents the results of experimental data on the use of combined soils in greenhouse conditions in the Orenburg region when growing ornamental plants Osteospermum, for the purpose of decorative landscaping in urban areas, as one of the promising flower crops. In laboratory conditions, when constructing the soil, its chemical composition was carried out before sowing ornamental crops and after transplanting plants into open ground, in order to analyze the needs of plants for the mineral component of the soil and the possibilities of its reuse (secondary) for enriching the open soil of flower beds in urban conditions.

The purpose of research is the ecological assessment of the impact of flood sedimentation on arable land of the Oka River floodplain agrolandscape. Research on studying the arrival of pollutants in the flood sediments on arable land floodplain agrolandscape was conducted in 2022-2023 on a stationary observation site of 16 ha, located 2 km from the northeastern administrative boundary of Ryazan Ryazan region (left bank of the central part of the Oka River floodplain near the village of Shumash). Studying sediment load was carried out by sampling sediments with the help of pile plastic mats imitating the top soil cover (mat area 0.14 m2) installed in advance in the control points (before the beginning of spring flooding). During the experiment, the value of sediment load was established, the content of pollutants in flood sediments in comparison with the underlying soil was studied, the degree of contamination of sediments with heavy metals and arsenic was assessed, and the structure of the influx of the studied chemical elements into the agrolandscape with flood sediments was analyzed. Of the pollutants considered, cadmium is more actively concentrated in flood sediments of the stationary observation site, followed by mercury, zinc, nickel, arsenic, manganese, lead, and copper and chromium less actively. The input of gross forms of heavy metals amounted to: copper - 260.5 g/ha; zinc - 1468.0 g/ha, lead - 255.8 g/ha; cadmium - 108.1 g/ha; nickel - 499.2 g/ha; chromium - 508.6 g/kg; mercury - 0.6 g/ha; arsenic - 115.6 g/ha; manganese - 8907.6 g/ha. The arrival of pollutants in the process of sedimentogenesis on the territory of agrolandscape in the floodplain of the Oka River indicates the need to organize and conduct environmental monitoring of the content of heavy metals and arsenic in flood sediments and underlying soil, as well as preventive measures to improve its buffer properties.

Relevance. The organic matter of the soils of the Non-Chernozem zone requires additional sources of its replenishment, which can include sewage sludge (SS). The paper investigates the use of sewage sludge from Tver, introduced fresh into a mixture with additional organic substrates (sawdust, peat, straw) in the field crop rotation link.Methods. The experiment was carried out in the Tver region on sod-podzolic sandy loam soil in fourfold repetition. OSV was introduced as part of a total dose of a fertilizer mixture of 60 t/ha with additional organic substrates (sawdust, peat, straw) taken in different proportions (1:1, 1:2, 1:3) at the beginning of the experiment. The area of the experimental plot is 6 m2. Crops of the crop rotation link — mixture vetch and oat, winter rye, spring barley. The content of organic matter, its group and fractional composition were determined in soil samples according to the methods generally accepted in agrochemistry.Results. The introduction of SS together with additional substrates contributed to an increase in the amount of soil organic matter (1,38–1,5%) and its maintenance in the aftereffect at the level of 1,33–1,49%, in the control variant this indicator was 1,26% (the significance of differences p < 0,05). The studied fertilizers provided an increase in the share of GA-1 and a decrease in FA-1a. In comparison with the finished compost, fertilizer mixtures, in which the components were in equal proportions, were ahead of the comparison options in their effect. They also contributed to the highest increase in productivity of the crop rotation link among all the variants of the experiment (an increase in control — 61,1–68,2%). Compost provided an increase in productivity by only 37,9%.
