Chernozem Soils

The influence of various levels of mineral nutrition on the accumulation of plant-root residues of spring wheat and oats in the conditions of the forest-steppe zone of Western Siberia is studied. The natural agricultural background of leached chernozem was taken as a control. The research was carried out at the station of the Department of Soil Science and Agrochemistry of the State Agrarian University of the Northern Trans-Urals. In the experiment, various doses of mineral fertilizers were used, ensuring the yield of grain crops from 3.0 to 6.0 t/ha. It was found that the mass of plant-root residues of spring wheat and oats has no significant differences and depends on the level of mineral nutrition. On the natural agricultural background, the mass of plant-root residues is 3.24-3.88 t/ha. Fertilization increases the yield of grain crops to 6.0 t/ha, and also increases the amount of plant-root residues: spring wheat - 4.47; oats – 6.04 t/ha. Increasing the doses of mineral fertilizers reduces the ratio of yield to the mass of plant-root residues from 1:1.6 to 1:1.10 units. It was found that almost half of the root system of spring wheat and oats is located in a layer of 0-10 cm, while the share of roots in a layer of 30-40 cm accounts for no more than 16% of the mass.

The paper presents data on the state of populations of species of the genus Daphnia in the ecosystems of small lakes in the forest-steppe zone of the south-west of Western Siberia, in which they are the highest trophic link. The research was conducted in 2017 on the territory of the Kurgan region. In total, 5 lakes (Lysanovo, Dolgoe, Golovka, Second Mogilnoye, Krutoyar) located between 66°30’ and 67°00 ‘ were studied.d. and 55°00’ and 55°30 ‘ s. The studied lakes are typical for the forest-steppe zone of Western Siberia. According to the chemical composition, the lake waters of the studied limnoecosystems can be attributed to the bicarbonate and chloride classes, the sodium group. 5 species of the genus Daphnia were found in the reservoirs: Daphnia (Daphnia) - D.(D.) pulex, D.(D.) obtusa, D.(D.) longispina, D.(D.) galeata, and Daphnia (Ctenodaphnia)- D. (C.) magna. Populations of D. (D.) pulex are found in all the studied reservoirs. The maximum density and biomass of crustaceans of this species is noted in Lake Mogilnoye of 51 thousand individuals/m² and 3.62 g/m², respectively. The minimum, in the lake Dolgoe – 3.8 thousand individuals/m² and 0.019 g/m². Of the other species, D. (C.) magna is most common-in three reservoirs. At the same time, there is a significant variability in the population density from 0.478 thousand. individuals/m² (Lake Krutoyar) up to 9,864 thousand. individuals/ m² (lake Dolgoe). D. (D.) longispina is found in two lakes – the Golovka (25,230 thousand. individuals/m²) and Krutoyar (6,428 thous. individuals/m²). The lowest occurrence is typical for D. (D.) obtusa (Lake Golovka) and D. (D.) galeata (Lake Lysanovo). The greatest species diversity of the genus Daphnia was observed in Lake Golovka (3 species) and Krutoyar (3 species). It is concluded that the studied limnoecosystems are characteristic daphnia reservoirs with the dominance of one or two species from the genus Daphnia.

The latitudinal changes of vegetation cover on the plains of Siberia are observed. In Western Siberia there are 4 zones (tundra and taiga, and forest-steppe and steppe only here), in Central and North-Eastern Siberia − only 2 zones (tundra and taiga).Tundra zone is represented by 4 subzones in Central Siberia; in Western and North-Eastern Siberia − by 3 subzones (there are no polar subzone). All 5 subzones of the taiga zone are distinguished both in Western Siberia and in the Central Siberia, but in the Central Siberia, forests are found in very high latitudes. The feature of the taiga zone of Western Siberia is high paludification. As a result, the vegetation of mires dominates over the zonal vegetation. Zonal West Siberian types are dark coniferous forests. Light coniferous forests predominate in the taiga zone of Central and North-Eastern Siberia. In the forest-steppe zone in Western Siberia forests are small-leaved − birch, aspen-birch (Betula pendula, Populus tremula). The abundance of mires is the feature of this zone, as well as in the taiga.
