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 article deals with the issues of maintenance and removal of mineral nutrition elements by plants of winter triticale on gray forest soils of the south-eastern part of the Volga-Vyatka zone, depending on the seeding rate and variety. The question of establishing the optimum density of sowing, the area of food for grain crops served as the object of study by many researchers [2,3,4,5,6]. The urgency of the issue of creating optimal sowing density is explained by the fact that the factors that determine the magnitude of the yield are constantly changing. Therefore, the study of patterns of formation of yield and removal of nutrients in connection with seeding rates remains an eternally new research topic. With a good harvest, winter triticale consumes and alienates a large amount of nutrients from the soil. With an increase in the seeding rates, respectively, the removal of mineral nutrients increases, and the seeding rate is important for the formation of a given density of productive stalk and removal of mineral nutrients. In production, these elements of technology are often underestimated and often unjustifiably overestimate the seeding rate, which is not necessary, since the really possible yield is achieved at an optimum seeding rate with minimal seed consumption.

Установлено, что на пойменных почвах использование методов диагностики минерального питания растений моркови «по почве» и «по черешку» в фазу начала образования корнеплодов позволяет значительно (на 36–42%) снизить расход минеральных удобрений, обеспечивая урожайность моркови на уровне 70 т/га с долей стандартной продукции 78–81% без существенного изменения качества корнеплодов.It was found that in floodplain soils, the use of methods of diagnosis of mineral nutrition of carrot plants «on the soil» and «on the petiole» in the phase of the beginning of the formation of root crops can significantly (by 36–42%) reduce the consumption of mineral fertilizers, ensuring the yield of carrots at the level of 70 t/ha with a share of standard production of 78–81% without significantly changing the quality of root crops.
