The features of the accumulation and distribution of organic carbon and nitrogen in the aggregates of the arable layer of leached chernozem (Luvic Voronic Chernozems) and gray forest soil (Luvic Retic Greyzemic Phaeozems) were evaluated. After dry sieving in structural separates of dimensional fractions >10, 10-5, 5-2, 2-1, 1-0.25, and <0.25 mm, the content of organic carbon and total nitrogen was determined in the laboratory. It was found that chernozem and gray forest soil significantly differed from each other in organic carbon in all fractions of structural separates. Lumpy aggregates (>10 mm) and fine earth (<0.25 mm) were characterized by an average spatial variability (CV up to 21%) of organic carbon and total nitrogen content. In chernozem arable layer, the maximum content of organic carbon and total nitrogen was in size fractions from 5 to 0.25 mm, whereas in gray forest soil – from 10 to 2 mm. Maximum value of C:N in gray forest soil was 16.0 units in aggregates with dimensions less than 0.25 mm, and in chernozem – in the lumpy fraction (> 10 mm), where the ratio was 15.1 units it was revealed that the content of organic carbon in structural units depends on the soil type by 21%, and on the dimensional fraction by 37%. The total nitrogen content is determined by 20% by the soil type and 36% by the size of structural aggregates.

“…The carbonate depth did not change over the period of 60 years and corresponded to 127±12 cm. In the remaining variants, carbonates have decreased from 125-128 to 135-138 cm over the years of research, thereby confirming the fact of increasing the leaching process when gray forest soils are involved in the arable fund [12,13].…”

We studied the changes in the agrochemical properties of the gray forest soil in the territory of Western Siberia’s sub-boreal zone affected by the long-term use of the organomineral fertilizers in the grain-follow-row crop rotation and in its absence. We used virgin areas of gray forest soil situated in the immediate proximity to the fields as a control. The anthropogenic changes of morphological features throughout the gray forest soil profile were identified based on the use of fixed permanent plots laid down in 1960. This paper describes the dynamics of the actual, exchange, and hydrolytic acidity as well as the amount of absorbed bases, together with the base exchange capacity and the degree of base saturation. The study of arable gray forest soil for the period 1960-2020 was performed. This provided an opportunity to identify the causes of its chemical degradation in the sub-boreal zone of the Trans-Urals under the conditions of a plant residue shortage. The systematic use of mineral fertilizers affects the base exchange capacity and triggers an increase in the arable layer’s acidity. The use of an organic fertilizer system stabilizes the chemical properties of gray forest soil.

This paper presents the findings of long-term field experiments to study the influence of increasing doses of mineral fertilizers on the technological and agrochemical features of Siberian-bred oat. The studies were performed in the forest-steppe zone of the Trans-Urals on leached chernozem. We have studied the varieties of cultivated oat of local selection: Talisman, Foma and Otrada on a natural soil preparation (control) and while applying fertilizers, in doses calculated to obtain the planned yield from 3.0 to 6.0 t/ha. It has been revealed that modern varieties of oat have genetic features for the assimilation of nutrients from the soil and fertilizers. It affects the content of protein, fat and starch in the grain. Accounting for the totality of indicators of the chemical composition, the Foma variety was distinguished. Its grain on fertilized variants contains: protein 10.8-15.3; fat - 3.0-3.6; starch - 33.0-45.7%. The use of mineral fertilizers results in an increase in the nitrogen content in grain and straw, and potassium - only in straw. The biological removal of nutrients depended on the level of mineral nutrition and the variety, giving ground for the development of a varietal system of fertilizers for oat in Western Siberia.
