“…When developing a fertilizer system and a crop rotation technology, it is important to use the methods of complex soil and plant diagnostics for optimizing plant nutrition and fertilizing, in which the ratio of nutrients, doses and timing of fertilizer application should be differentiated depending on the variety and economic purpose of the product [1,7,8].…”

The crop rotation productivity depends on the crops and chemicals used, especially fertilizers. Cultivation of crops makes it possible to obtain environmentally safe products due to biologically correctly selected predecessors and with the correct alternation of crops in space and time. This allows for savings in plant protection products and differentiated use of fertilizers. Based on the results of 28-year research into the yield and productivity of crop rotation with the use of various doses of fertilizers, the regularities of changes in the content of mobile phosphorus and exchangeable potassium in the soddy-podzolic medium loamy soil of Vologda Oblast were revealed, and regression models that reflect their relationship with the productivity of crop rotation were built. The results made it possible to build a non-linear regression model that reflects quantitative features of the dependence of crop rotation productivity on the levels of mobile phosphorus and exchangeable potassium. With an increase in the content of mobile elements in the soil in the case of mobile phosphorus, the productivity of crop rotation will increase with a slight slowdown with each single dose, and in the case of exchangeable potassium it will increase evenly.

“…Moreover, in light-textured soils, there is a risk of fertilizer loss caused by leaching [32,33]. Currently, in many regions of Russia, there is an imbalance of nutrients in soils with a predominance of losses over accumulation [34]. Consequently, there is also a demand to develop optimal and cost-effective fertilizer systems to ensure sustainable canola yield and seed quality [35].…”

Soil Sulfur Deficiency Restricts Canola (Brassica napus) Productivity in Northwestern Russia Regardless of NPK Fertilization Level

Canola cultivation at high latitudes is becoming more promising in terms of modern climate change. Sustainable crop production requires an understanding of yield-limiting factors, which need to be adjusted in agricultural management first. Therefore, our study was aimed at examining the effect of climate and soil fertility factors on the canola yield from 2012 to 2015 in northwestern Russia. Simultaneously, effectiveness of chemical fertilizer (N65P50K50 and N100P75K75) rates was tested. Studied soils had light texture, high acidity and severe sulfur deficiency. Canola yield (Y) varied from 0.81 to 1.60 t·ha−1 for the observed period. Applied fertilizer increased Y by around 30%, but this change was not significant. Climate effect testing with the FAO-AquaCrop simulation showed no noticeable water and heat stresses for the study period (0% to 20% reduction in potential Y). Among the tested soil properties, the content of organic carbon, available nitrogen and sulfur significantly correlated with Y (r = 0.58–0.66). Combining these factors together with soil pH in a path model explained 60% of variability in Y. Importantly, sulfur had the highest and most significant effect in this model. Thus, this soil parameter is the main yield-limiting factor in the study area, which must be the first to be adjusted in agricultural practice.

“…Indeed, the quality of soil structure, the formation of the soil profile, the provision of soil with nutrients depends on humus [5]. At the same time, nutrients, mainly nitrogen, become available to plants in the process of humus mineralization [6]. During the cultivation of agricultural plants, partial replenishment of soil humus occurs due to the arrival of crop and root BIO Web of Conferences 36, 03002 (2021) https://doi.org/10.1051/bioconf/20213603002 FSRAABA 2021 residues in the process of their mineralization and humification.…”

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.
