The article presents the results of a vegetation experiment on studying an effect of increasing doses of nitrogen (factor С - N0; No.o5; No.io; N015; No.2o; N0,25 g/kg of absolutely dry soil) and pre-sowing inoculation of seeds with biological preparation "Risotorphine" (factor В - no inoculation; by inoculation) on the formation of vegetative mass and grain yield ofpeas at cultivating in the conditions of a poorly cultivated (factor A0) and of a medium cultivated (factor A f sod-podzolic soil. Cultivation degree of soil was expressed by such criteria as power of an arable horizon, value of metabolic acidity and content of mobile phosphorus, a degree of saturation of soil with bases. For experience tab there were used Mitscher-lich cups with a capacity of 5 kg of absolutely dry soil (a.d.s.), in 16 repetitions of options. The experiments were conducted in the conditions of vegetation site on the territory of University Scientific Centre "Lipogorie" of FSBEI Perm GATA, guided by a science-based methodology. When harvesting peas for a green mass more intensive development and productivity of plants (23.3 and 58.9, 40.0, 78.8 g/cup, respectively) in the phase of stem branching and budding a beginning offlowering that is recorded for its use on the background of inoculation, usage of mineral nitrogen in a dose of 0.10 g/kg on a poorly cultivated soil and 0.15 g/kg a.d.s. on a medium cultivated soil. Applying of higher doses of nitrogen has a depressing effect on development of assimilating surface of pea plants on a poorly and a medium cultivated soil. When raising pea plants before harvest maturity of grain: in the conditions of a poorly cultivated soil for yield at the level of 7.92 g/cup, the process of carrying on only an inoculation of seed with microbial preparation "Rizotorfin" can be considered; in the medium cultivated soil varieties, plant peas impose higher requirements for the level of mineral nutrition the maximum yield in the experiment (which 9.22 g/cup), noted at a combined use of inoculation and mineral nitrogen in a dose of 0.20 g/kg a.d.s.

Aim. To determine physiologically expedient rates of mineral nitrogen in winter rye production on sod-podzol- ic soils based on the orientation of the processes of biological nitrogen transformation in the plants rhizosphere. Methods. Field studies, gas chromatography determination of potential nitrogen fi xation activity and potential emissions of N 2 O. Results. The results obtained have demonstrated that the rates of mineral nitrogen, not ex- ceeding 60 kg/ha, can be considered physiologically expedient for winter rye production on sod-podzolic soils. Under the application of microbial preparation Diazobakteryn, there is a higher physiological need of plants for nitrogen, which allows increasing the rates of nitrogen fertilizers up to 90 kg/ha. Conclusions. The orienta- tion of the processes of biological nitrogen transformation in the root zone of plants is a reliable indicator of determining the appropriateness of nitrogen fertilization of crops.

The circular economy concept promotes the recycling of agricultural waste. This study was aimed at investigating the effects of cattle horn shavings on apple tree nitrogen nutrition. Ligol apple trees on P 60 rootstock were the object of the study. The experiment was conducted in the experimental orchard of the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry, from 2015 to 2018. Two fertiliser rates were tested: 50 and 100 kg/ha N. Horn shavings (14.1% N) were applied at the end of autumn or at the beginning of vegetation in the spring and in one treatment 100 kg/ha N rate was divided into two equal parts and applied both in autumn and spring. The effects of the horn shavings were compared with the effects of ammonium nitrate (34.4% N) and the unfertilised treatment. The lowest mineral nitrogen content was found in the unfertilised orchard soil and the soil fertilised with horn shavings in the spring at 50 kg/ha N equivalent. In all other cases, the fertilisers increased the soil’s mineral nitrogen content. The lowest leaf nitrogen content was found in apple trees that grew in the unfertilised orchard soil or soil fertilised in the spring with 50 kg/ha N of horn shavings (1.58–2.13%). In other cases, leaf nitrogen content was higher (1.77–2.17%). The apple trees with the lowest leaf nitrogen content produced the smallest average yield (34.5–36.6 t/ha). The highest yield was recorded from fruit trees fertilised with 50 kg/ha N of ammonium nitrate applied in spring or horn shavings applied in autumn (42.4 and 41.4 t/ha, respectively). The influence of horn shavings on the other studied parameters was similar to that of ammonium nitrate. Horn shavings, like nitrogen fertiliser, could facilitate nitrogen nutrition management in apple trees, especially in organic orchards, where the use of synthetic fertilisers is prohibited.

Abstract. The purpose of the research was to determine the most effective technological method of applying the LPB biological preparation on spring wheat crops. Research methodology and methods. Studies were conducted on sod-podzolic soil in 2017–2019 in the Tver region. The composition of the LPB includes agronomically useful microflora (from n×109 to n×1012 CFU/ml), physiologically active substances, a complex of macro- and micronutrients. The following technological techniques were studied: seed treatment before sowing, double foliar treatment of vegetating plants, and combining these techniques. Results. All the studied technological methods of application of LPB contributed to an increase in the yield of spring wheat grain. The highest yield on average for three years of research was obtained by combining the methods of seed treatment with a 1% solution of LPB and foliar treatment plants at a dose of 3 l/ha – 2.96 t/ha (in the control of 2.63 t/ha). The maximum yield is formed primarily by increasing the productivity of stems (95 %). In addition, the use of LPB in all research variants contributed to a significant increase in the number of grains in the ear by 1.2–1.9 PCs, there was a tendency to increase the mass of 1000 grains. Observed an increase in the nitrogen content in the soil in the variants with the introduction of LPB due to the activation of the nitrogen-transforming microflora, which is confirmed by correlations. The increase in nitrogen nutrition of wheat and the biochemical processes that take place in plants under the influence of LFB, led to an increase in the protein content of wheat grain. Scientific novelty. A new promising biological product of the LPB is proposed, for which the most effective agrotechnological method of application for spring wheat crops is selected, which allows to increase the yield of this crop, its quality, as well as improve the agrochemical and microbiological parameters of the soil.

Цель исследований изучение потенциальной возможности получения максимальной урожайности новых гибридов капусты белокочанной при оптимизации ее питания на пойменных почвах Подмосковья. На окультуренной аллювиальной луговой среднесуглинистой почве поймы реки Москвы (Раменский район) в 20182019 годах проведены исследования по увеличению продуктивности нового гибрида поздней белокочанной капусты F1 Континент. Почвы характеризовались близкой к нейтральной реакцией среды, благоприятными агрофизическими свойствами, довольно высоким содержанием гумуса. Погодные условия 20182019 годов были в целом неблагоприятны для возделывания капусты: длительные засушливые периоды оказали сильное влияние на продуктивность растений капусты. Дефицит влаги восполняли дополнительными поливами. В схему опыта включены варианты с расчетными дозами минеральных удобрений (на урожайность 80, 100 и 120 т/га), использование анализа почвы и растений для определения необходимости подкормок, а также природный регулятор роста растений экстрасол (2 л/га) для оптимизации азотного питания капусты. Возделывание гибрида в условиях низкого (N90P50K135), среднего (N180P100K270) и высокого (N370P101K362) уровня минерального питания, с применением регулятора роста экстрасола (2 л/га) и подкормок азотно-калийными удобрениями в фазе розетки листьев позволило увеличить урожайность с 53 до 7585 т/га (на 4161) с выходом стандартной продукции более 90. Прибавка урожайности к варианту без удобрений (контроль) за счет улучшения питания растений составила 761, окупаемость 1 кг д.в. удобрений дополнительной продукцией в размере от 19 до 62 кг. При улучшении минерального питания отмечено увеличение содержания сахаров и витамина С в продукции, однако увеличение доз азотных удобрений более 250 кг/га д.в. в составе полного минерального удобрения приводит к превышению ПДК (500 мг/кг сырой массы) по нитратам и снижению содержания сухого вещества в кочанах. Окупаемость затрат на удобрения капусты по лучшим вариантам достигла 4762 кг продукции на 1 кг д.в. удобрений.The purpose of the research is to study the potential possibility of obtaining the maximum yield of new hybrids of cabbage when optimizing its nutrition on floodplain soils of the Moscow region. The studies were conducted to increase the productivity of a new hybrid of late cabbage F1 Kontinent on cultivated alluvial meadow medium loamy soil of the Moscow river floodplain (Ramenskii district) in 20182019. The soils were characterized by a close to neutral reaction of the medium, favorable agrophysical properties, and a rather high humus content. The weather conditions of 20182019 were generally unfavorable for the cultivation of cabbage: long dry periods had a strong impact on the productivity of cabbage plants. The deficit of moisture was compensated by additional irrigation. The experimental design included options with estimated doses of mineral fertilizers (for yields of 80, 100 and 120 t/ha), the use of soil and plant analysis to determine the need for fertilizing, and the natural plant growth regulator Extrasol (2 l/ha) to optimize nitrogen nutrition cabbage. The cultivation of the hybrid conditions is low (N90P50K135), medium (N180P100K270) and high (N370P101K362) mineral nutrition level, using the growth regulator Extrasol (2 l/ha) and fertilizing nitrogen-potassium fertilizers in the leaf outlet phase allowed to increase the yield of heads from 53 to 7585 tons per hectare (by 4161) with the output of standard products more than 90. The yield increase amounted to the option without fertilizers (control) due to improved plant nutrition 761, payback 1 kg a.s. fertilizers with additional products in the amount of 19 to 62 kg. An increase in the content of sugars and vitamin C in products was noted with an improvement in mineral nutrition, however, an increase in doses of nitrogen fertilizers of more than 250 kg/ha a.s. as a part of a complete mineral fertilizer leads to an excess of MPC (500 mg/kg of crude mass) in nitrates and a decrease in the dry matter content in heads of cabbage. Payback of the cost of cabbage fertilizers for the best variants reached 4762 kg of products per kg of a.s. fertilizer.

The paper depicts the study of mineral nitrogen and pre-sowing seeds bacteryzation on the development of nitrogen fixing bacteria and the activity of autotrophic and heterotrophic nitrification. It was revealed that nitrification activity in the root zone of winter rye plants rises together with the increase of mineral nitrogen doses. Heterotrophic nitrification plays a significant role in the formation of nitrate pool in the root zone, especially during the early stages of plants organogenesis. Application of the microbial preparation Diazobakteryn had enhanced the activity autotrophic and heterotrophic nitrification processes in the rhizosphere soil of plants in the spring, during the early stages of their development while during the next organogenesis phases the reduction of nitrification processes was observed. In plants-free soil the contribution of heterotrophic nitrification to biological transformation of nitrogen was negligible.

Abstract The possibility of using peat as a solid base for a microbial preparation was investigated. The basis of the microbial consortium of the drug was made up of Pseudomonas extremorientalis and Aeromonas media isolated from coprolites of the earthworms Eisenia fetida, Savigny. Among the studied peat species, eutrophic woody peat (pH = 5.7, degree of decomposition 48%) was chosen, which stimulated the increase in the aboveground mass (+ 11%) of wheat seedlings in preliminary tests. We assessed the viability of bacteria within 2 months after their adsorption on peat. On the 56th day of the experiment, the number of A. media in the variant with a peat carrier remained at the highest possible level - 107 CFU / ml. In a vegetation experiment, it was found that the use of two microbial cultures (in liquid form and in solid after adsorption of bacteria on peat) for presowing seed treatment led to an increase in wheat germination by 9% (83% for the liquid form and 92% for the solid form). Plant biomass increased in variants using bacteria on peat compared to using bacteria in liquid form. The presence of peat and P. extremorientalis increased the aboveground weight of wheat by 5%, while peat with a mixture of bacteria increased this figure by 15%. In variants with the use of P. extremorientalis on peat, the rate of development of plant diseases decreased in comparison with the liquid form by more than 3 times. With the combined use of bacteria, peat provides high rates of germination of seeds and aboveground mass. The research results indicate a greater efficiency of using a solid preparative form of a microbial preparation in comparison with a liquid one.

In the period of 1983-1985, 18 field experiments with potatoes grown for industrial starch production were set up in the Netherlands to investigate the effects of poultry-slurry application on tuber yield and on soil mineral nitrogen. Slurry was applied in autumn with and without the nitrification inhibitor dicyandiamide (DCD) and in spring without DCD. Control treatments without slurry or DCD were included. Various nitrogen fertilizer rates were applied to all slurry treatments. In autumn, following slurry application without DCD, slurry-derived nitrate moved to the 0.3-0.6 and 0.6-1 m soil layers. Following DCD-application, most of the slurry-derived nitrate remained in the 0-0.3 m soil layer. Maximum yields as estimated from a nitrogen fertilizer response function were slightly increased by the slurry application. Nitrogen supplied from the slurry decreased the amount of fertilizer nitrogen needed for maximum yield. Increasing the amounts of soil mineral nitrogen in June from slurry or applied inorganic nitrogen fertilizer increased residual soil mineral nitrogen at harvest.

Mineral nutrition and plant ontogeny influence both the physiological balance between nutrients in a plant and determine the proper nutritional status of a plant, which is necessary to realize the yielding potential of a cultivated species. The aim of the present study was to assess the effect of nitrogen doses (0, 4, 8, 12, 16 g N·m−2) and plant development phases (the beginning and full flowering) on the content of macroelements and changes in ionic ratios occurring in the herb of the summer savory cv. ‘Saturn’. The two-factor experiment was carried out in a random-block design with five replications. The mineral nitrogen nutrition applied increased the concentration of total nitrogen and its mineral forms in the plants. There was a change in ion homeostasis in the individual stages of the ontogenesis process, i.e., a higher content of P, K, Ca, and S in the initial flowering phase as well as Mg and Cl in the full flowering phase. The increase in the availability of mineral nitrogen in the soil solution caused a decrease in total sorption capacity, reducing the potential of the soil for saturation with alkaline cations.

Micro-field experiment was carried out with the application of oats and timothy biomass, and nitrogen fertilizer marked by stable isotope of the 15N, and manure for the use of nitrogen by plants, and the flows of this element were analyzed in the system "fertilizer -soil-atmosphere". It was found that the barley consumes the most amount fertilizer nitrogen and soil nitrogen when applying a nitrogen mineral fertilizer; the consumption of the oats and timothy nitrogen biomass decreases by 18-36% and 6-36% respectively. Application of the oats and timothy biomass increases nitrogen immobilization in the soil and agrophytocenose resistance from 1.6 to 1.8 times, decreases gaseous losses of their nitrogen from 1.4 to 2.0 times in comparison with nitrogen fertilizer (stress mode). Manure application decreases nitrogen losses from the oats and timothy biomass by 1.6 times. Maximum yield of grain the barley forms when using nitrogen fertilizer as a result of its access in the soil. Application the cereal crops biomass either separately, or along with manure reduces the yield of barley by 30-13% compared with nitrogen fertilizers, which affect nitrogen flows in the agroecosystem.
