Positive Effect

The results of long-term research in experiments with crop rotations with different clover saturation are presented. It is shown that the cluster has a positive effect on the main indicators of vegetation of dark-gray forest soil. The introduction of two fields of perennial grasses into the six-field crop rotation significantly increases both the humus reserves and increases the productivity of arable land by 1.5–2 times compared to the crop rotation with a field of pure steam.

Studies, were conducted in a stationary experiment between 1988 and 2018 on dark gray forest heavy loam soil in Scientific Research Institute of Agriculture for Northern Trans-Ural Region - Branch of Federal State Institutions Federal Research Centre Tyumen Scientific Centre of Siberian Branch of the Russian Academy of Sciences. The aim of the study is to determine the effect of long-term (30 years) impact of different systems of basic cultivation of dark gray forest soils in the cultivation of grain crops on the humus content. Observations were made according to generally accepted methods during 6 rotations of grain and fallow crop rotation: bare fallow, winter rye, spring wheat, spring vetch, spring barley, unfolded in time and space. The impact of the combined system of tillage with alternation of plowing and no-tillage at 20-22 cm during 6 rotations of a 5-pole grain and steam crop rotation (30 years), increased the humus content in the 0-40 cm layer of dark gray forest soil compared with the initial content by 0.42%. The systems of main tillage - differentiated, without sowing, and mouldboard provided in general a relatively favorable dynamics of the humus state of the soil. The content of humus in the 0-40 cm layer of soil by differentiated and unswept systems during the study period remained close to the initial condition. По отвальной системе содержание гумуса снижалось на 0,22% или в среднем 0,37т/га в год. The greatest loss of humus in the 0-40 cm layer of soil by 0.80% in relation to the initial was the impact of surface treatment with annual discing BDT-2,5 (heavy disc harrows) on 10-12 cm or an average annual loss of 1.33 t / ha.

The aim of the research is to establish the peculiarities of the formation of the nutrient regime of gray forest soil with different systems of basic cultivation, fertilization and sealing of by-products of crops in short-rotation 4-field grain crop rotation – winter wheat–corn for grain–barley–soybean. Evaluate the quantitative inflow of biomass, participation in the formation of the nutrient regime of gray forest soil, especially the differentiation of 0–40 cm of soil layer depending on the distribution of nutrients in different tillage soil systems. The studies were carried out in a long-term stationary experiment of the department of soil cultivation and weed control of the NSC «Institute of Agriculture of the NAAS», founded in 1969. The fertilization system consisted of the application of mineral fertilizers N65Р58К68 kg acting things per 1 ha of crop rotation area. As an organic fertilizer, we used by-products of crop rotation, where during 2009–2013 received an average of 5,17–5,50 t/ha, and 2014–2017 – 6,65–7,76 t/ha of crop rotation. The existing yield of the main product significantly influenced the volume of the non-commodity part, with the growth of the main product, the growth of by-products also took place in direct proportion. Nitrogen removal averaged 105 kg/ha, and with biomass it returned on average 55,4 kg/ ha, nitrogen with a full mineralization cycle, in general, this corresponds to 45–47 % of the share of costs. In general, the return of phosphorus from by-products for the rotation of 5 received an average of 12,0–16,7 kg/ha and 4-field crop 26 rotation 19,5–22,0 kg/ha, which was 35–40 % of the total removal harvest. The soil received many times more potassium from the biomass of agricultural crops than part of the cost of the main product, due to the attraction of the maize leaf mass, from which an average of 177–253 kg/ha enters the soil, and for crop rotation – 61,4–95,4 kg/ha per hectare of sown area. Key words: gray forest soil, soil nutrient regime, recycling of nutrients, main and by-products of crops.

Spring Rape

The work is devoted to the assessment of the impact of a single oil pollution of the soil on the yield and disease incidence of spring rape plants (Brassica napus L.). The study was conducted in experimental site of agrochemistry and soil science department of Kazan State Agrarian University, which is located in Predkamye zone of Tatarstan Republic. The soil in experimental site is clay loamy gray forest soil, which is typical for this zone. The main nutrient properties of uncontaminated soil was low content of humus, slightly high content of labile Phosphorous and moderate availability of labile Potassium, the pH was slightly acid. The soil was intentionally contaminated by crude oil on soil surface at the rates of 10, 20 and 40 l/m2. Based on the previous research, the contamination levels in this study are presented as low, moderate and high levels. The yield of oilseeds of spring rape was closely correlated with the level of one-time pollution of gray forest soil with crude oil over at least 15 years. The results showed that the increase of downy mildew abundance (R2=0,8804) and development(R2=0,8610) correlated with the soil contamination level. Consequently, both abundance and development of downy mildew induced asignificant negative effect on the yield of the main and side rape production. The strength of oil seeds production correlation with the level of plant infection (R2=0,8652÷0,8759) was more significant as compared to the correlation strength with the decrease of rape shoot yield (R2=0,8013÷0,8192)

The article offers studies to determine the effectiveness of processing methods for the productivity of spring rapeseed and surepitsa on the dark gray forest soil of the Ryazan region. As a result, it was revealed that the maximum intensity of decomposition of flax tissue was recorded in the steam link of the crop rotation using the dump method of basic tillage for oilseed cabbage crops. The maximum yield of rapeseed was observed on the variant of the steam link of crop rotation + dump processing (31.3 c / ha), in the surepitsa (25.6 c/ha). A high increase in oilseeds in this variant is 4.7 c / ha, where the NSR05 factor with 0.97 c / ha relative to the minimum basic tillage was recorded in 2015. In the experiment, the trends of increasing the yield of oilseeds of spring rapeseed and surepitsa in the fallow link of the crop rotation relative to the row crop are revealed. The maximum oil content of rapeseed was noted in the rowed link of crop rotation during milling tillage (47.6%); in surepitsa – in the rowed link of crop rotation also during milling (45.1%).
