The issues of the recoupment of potash fertilizers are considered, which is one of the most controversial in agronomy, since it is precisely this that determines the need for fertilizers and the economic efficiency of their use. It is shown that the payback of fertilizers is a complex value and not constant in different crops. The increase in yield from fertilizers in kind is taken on the basis of field experiments with fertilizers carried out on podzolized chernozem in the Uman NUS. The cost of the increase in yield from the use of potash fertilizers was determined by the average actual sales prices of products prevailing on the market through various sales channels in the 6th quarter of 2021. collecting a yield increase from potash fertilizers. The cost of potash fertilizer was taken at the current price of 16000 UAH/t with the addition of a margin for their delivery to the farm. The costs for the use of fertilizers on the farm and for collecting the increase in yield were set calculated according to the accepted standards. The difference between the value of the yield increase (YI) and additional costs (AC) gives the net income received from the use of fertilizers. The ratio of the cost of increasing the yield to additional costs shows their payback. On the basis of comparing the indicators YI and AC, the boundaries of the economic efficiency of the use of fertilizers were determined: YI>AC (general expression of the task). The minimum necessary increase in yield from fertilizers and the limits of the increase in prices for potash fertilizers were also calculated. It has been established that at a price for potassium chloride of 16000 UAH /t and the cost of its use in optimal doses for field crops against the background of a balanced nitrogen-phosphorus nutrition, the cost of an increase in yield is 1164–14820 UAH/ ha. Payback (unprofitableness) of 1 kg. potash fertilizers vary in a wide range – from – UAH 18.6 to 104,0, depending on the crop. The limit of the unprofitable price per unit of the active substance of potash fertilizers at the optimal dose of application depends on the crop and is in the range of 6.9–129,5 UAH/ha. With the current disparity in prices for crop products and potassium chloride, its use is unprofitable for winter rye, spring barley, grain sorghum and sugar beet (when applied against a background of 40 t/ha of manure). This is due to the availability of podzolized chernozem with mobile potassium compounds, biological characteristics of crops and technologies for their cultivation.

The issues of recoupment of nitrogen fertilizers are considered, since they determine the need for fertilizers and the agro-economic efficiency of their use. It is shown that the payback of fertilizers is a complex value and not constant in different crops. The increase in yield from fertilizers in kind is taken on the basis of field experiments with fertilizers carried out on podzolized chernozem of the opita field of the Uman NUS. The cost of an increase in the yield from the use of nitrogen fertilizers was determined by the average actual sales prices of products prevailing on the market through various sales channels in the 6th quarter of 2021. Additional costs included: the cost of fertilizers, a margin for their delivery to the farm, the cost of using it on the farm and collecting increase in yield from nitrogen fertilizers. The cost of ammonium nitrate was taken at UAH 24,000 / t with the addition of a margin for their delivery to the farm. The costs of using fertilizers on the farm and collecting an increase in yield were set calculated according to the accepted standards. The difference between the value of the yield increase (PU) and additional costs (AD) gives the net income received from the use of fertilizers. The ratio of the cost of increasing the yield to additional costs shows their payback. On the basis of comparing the indicators of PU and DZ, the boundaries of the economic efficiency of the use of fertilizers were determined: PU> DZ (general expression of the task). We also calculated the minimum required increase in yield from fertilizers and the limits of price increases for nitrogen fertilizers. It has been established that at a price of ammonium nitrate of UAH 24,000 / t and the cost of its use in optimal doses for field crops against the background of a balanced phosphorus-potassium nutrition, the cost of an increase in yield is 3075–47894 UAH/ha. Payback of 1 kg a.c. nitrogen fertilization varies in a wide range – from 3.0 to 217.3 hryvnyas, depending on the crop. The limit of the unprofitable price per unit of the active substance of nitrogen fertilizers at the optimal application rate depends on the crop and is in the range of UAH 76.5–219.0 /ha. With the current disparity in prices for crop products and ammonium nitrate (24,000 UAH/t), its use is profitable, which is explained by the low ability of podzolized chernozem to provide plants with nitrogen, biological requirements of crops for this food element and technologies for their cultivation. Key words: nitrogen fertilizers, agricultural crops, fertilizer recoupment, loss threshold, price increase limit.

The results of research conducted in 2016‒2018 on the southern chernozem andthe effect of two varieties of spring barley extra-root feed on the formation of grain productivityare given. Based on the results obtained, indicators of agroeconomic efficiency and their changewere determined under the influence of this event (as one of the most important elements of technology)in growing the crop, including in terms of varieties. Despite the increase in productioncosts, the treatment of plant seeding with biologics contributed to a certain increase in notional netprofit, which increased with the number of feeds, reaching the highest values if used to optimizethe nutrition of Fresh florid (300 g/ha). One feeding of Stalker variety is determined at the levelof 5927, two feeding ‒ 6890, three ‒ 7320 UAH, and 3857 UAH/ha ‒ in control. The mentionedindicators were 5968, 6808, 7771 and 3980 UAH/ha, respectively, when the spring barley varietyVakula was grown. One of the most important indicators of economic efficiency decreased‒ the cost of growing a unit of production with an increase in the number of extracurricular feeding.The lowest indicator was the cost price of production of top – dressing with Fresh florid(300 g/ha ‒ according to the Stalker variety): with one extracorporeal sowing ‒ 2269.4; two treatments‒ 2173.5, and three ‒ 2166.7 UAH/t; in control, this indicator was 2638.5 UAH/t. Thesevalues were, respectively, 2262.3; 2185,8; 2105.4 and 2608.0 UAH/t when the barley spring varietyVakula was growing. The use of other biological preparations led to a certain increase in thecost of growing spring barley. The highest values were recorded when using Organic D-2 M withonly one feeding in the plant phase. In this version of the experiment the cost of growing a unitof production even slightly exceeded control, when Vakula variety was grown. The cultivation ofspring barley on the basis of resource saving using modern re-regulating substances and biologicalpreparations is advisable, because it increases not only the level of grain yield, but also themain indicators of agro-economic efficiency - net profit and profitability, and unit cost, on thecontrary, decreases. It was established that by optimizing the nutrition of spring barley on thebasis of resource saving by treating crops in the main growing seasons with biological products,along with increasing grain yield and changes in its quality, other indicators of agro-economicefficiency of crop production increase. The level of profitability in control (treatment of plantswith water) for the cultivation of barley of the spring variety Stalker was 59.2%, then in themost optimal food options it reached 93.8%, and for the Vakula variety they were determined61.0 and 99.5% respectively. The obtained agroeconomic indicators in the cultivation of springbarley made it possible to substantiate the following claims: the use of biologics to treat thesowing of spring barley plants during the main periods of vegetation increases the yield and costof grown grain. It was determined that the level of profitability of growing spring barley witha large number of feeds grew. The indicator reached its maximum value with three times theplanting of barley plants of the spring variety Vakula with Fresh florid, that is, 300 g/ha (99.5%).Two plant crops with this drug provided profitability at the level of 99.1%, and one ‒ 85.6, (incontrol ‒ 61.0%). The highest profitability of cultivation was ensured by the use of Fresh florid(300 g/ha) for optimizing nutrition three times for vegetation ‒in the phases of tillering, shootingand heading. The lowest level of profitability was ensured by the use of the preparation OrganicD-2 M for feeding barley of the spring variety Vakula: one treatment of plants ‒ at the level of60.6%, two ‒ 72.5, three treatments ‒ 78.2%. According to the results of research conductedwith two varieties of spring barley, the best biological product and terms of fertilization weredetermined in order to increase grain yield and improve its quality and agro-economic efficiencybased on the calculation of cost economic indicators. The expediency of nutrition optimizationby using modern biological products for spring barley cultivation has been confirmed.

Abstract Soybeans have become widespread in the world crop production as a valuable oilseed and high-protein crop with a unique biochemical composition. In the Russia in 2015-2019 annually there is an increase in acreage, yield and gross yield of soybeans. The research purpose is to substantiate the most effective system of basic soil cultivation during the soybeans cultivation in the Samara region. The research tasks included: to study the peculiarities of the soybeans yield formation depending on the main tillage systems, to evaluate the economic efficiency of the main tillage systems. It was found that the basic tillage system provided the best conditions for the formation of the soybean in 2018-2019. Thus, the highest yield was obtained in the variant with plowing by 20-22 cm and amounted to 14.9 cwt/ha, the lowest in the variant without autumn mechanical tillage - 10.1 cwt/ha. The calculation showed that the soybeans cultivation in all variants was effective. Direct costs in the soybeans cultivation varied according to the studied options from 15879.28 rubles/ha to 17767.34 rubles/ha, the cost price - from 1192.4 rubles/cwt to 1572.2 rubles/cwt. The basic tillage system with elements of minimization reduced direct costs, however, due to the lower yield, the highest net income was obtained in the variant with plowing by 20-22 cm and amounted to 19482.7 rubles/ha, with a profitability of 109.7%.

The articles offers the results of studies on the effect of sowing methods, seeding rates and backgrounds supply on yield and economic efficiency of broad bean cultivation for seeds. Increase seeding rate of 0.4 to 0.8 million units per hectare, regardless of sowing methods, increased the content of crude protein at 2.5-3.3 %. Similar changes occurred in the sugar content of the grain. In contrast, with increasing seeding rate, in wide-space sowing and calculated doses of fertilizers usage, resulted in a decrease of crude fiber, fat and ash. Adding the calculated doses of mineral fertilizers at planting in wide-space sowing with a rowing space of 45 cm and seeding rate of 0.6 million units per hectare provides about 10 thousand rubles per hectare, and the profitability level was 78 percent. Formation of high yields of green mass (41.0 tons per hectare) and grain ( 2.34 tons per hectare) of broad bean noted, when adding calculated doses of mineral fertilizers at wide-space sowing method with a seeding rate of 0.6 million units per hectare. I this way, we can see the high net income ( 9742.8 rubles per hectare), the level of profitability (78.0 %) and the cost of 1 ton of grain (5336.4 rubles per ton). The calculations of economic efficiency of fodder beans cultivation for grain showed that a high profitability obtained by making calculated doses of fertilizers, with a rowing method of sowing and seed rate of 0.7 million units per hectare was 59.4 %, while in wide-space sowing (45 and 60 cm) with a seeding rate of 0.6 million units per hectare was 78.0%.

Enterprise-wide risk management is a relatively new scientific and practical area of a corporate government, which has a special mission to deal with corporate risks and exposures and to achieve beneficial risk management outcomes. Risk management has a wide range of methods, techniques and tools, but quite expensive, but in the case of a successful application, can stimulate an increase in the company's value. Nevertheless, despite its relevance, risk management reluctantly introduced to the company, this is due, primarily, to the inability to pre-determine the economic impact of existing activities. Most methods for assessing the cost-effectiveness of risk management, as a rule, designed to assess the economic impact after the fact, in this article, the author has provided the tools for assessing the financial and economic impact of the implementation of risk management in advance.

The reason for the appearance of the first distributed generation in Russia was the high requirements to the reliability of power supply to power consumers of a special group of the first category of reliability. Diesel generating units were used to ensure uninterrupted operation. High costs for technological connection of consumers of the 1st and 2nd categories of reliability have strengthened the tendency to install a backup energy source in the enterprises' own power supply systems. However, setting reserves leads to a decrease in economic efficiency. There are additional costs for maintaining the reserve in a working condition. As a result, enterprises transfer the backup units to the mode of the main power source, and that of the backup function to the centralized power supply system. The creation of such industrial MiniGrid operating in a mode without power supply to the grid increases the cost of electricity for other consumers. Besides, with the departure of industrial enterprises from the centralized power supply, the share of communal and non-industrial consumers is growing. This requires an increase in the manoeuvrability of energy sources. The creation of balanced Energy Cells for energy supply to the population and small and medium-sized businesses that provide services to the population is not accompanied by the negative effects indicated above. In Russia, there are isolated examples of such systems, similarly operating in a mode without supplying power to the grid. Changes are needed to allow active consumers to supply excess capacity to the grid during peak hours in the UES of Russia, for which the grid companies need to be allowed to operate at least in a mode without supplying power to the grid, which will not lead to a decrease in grid companies' revenues from electricity transmission services. The introduction of these changes does not only lead not only to an increase in the reliability of power supply but also to an increase in the economic efficiency of the UES, which will reduce the price of electricity.

The idle lands of the Non-Chernozem zone of Russia are quickly overgrown with tree and shrubby vegetation (TSV). Their active development under modern conditions needs a comprehensive justification of the available technological options for removal and processing of TSV. To evaluate their agro-economic efficiency, a comprehensive study was carried out at Sofia LLC in the Tosnensky District of the Leningrad Region. Its methodological basis was model-field and production experiments, laid out in weakly and medium-cultivated sod-podzolic gleyey soils of heavy loamy granulometric composition. They studied the agroeconomic efficiency of application of traditional ameliorants (milled raw dolomite and poultry manure supplemented with potassium fertilizer) and TSV processing products (wood chips, wood chaff, biochar and ash). The study determined the negative impact of products of TSV processing embedded in the soil on crops; the lack of a direct correlation between agroecological and economic efficiency of development technologies; an irreplaceable positive role of a complex of chemical ameliorants. The level of profitability of its use varied in experiments from 7–15 % for cultures and varieties undemanding of fertility to 48–56 % for demanding ones. On its basis, radical improvement of the soil properties was ensured, which made it possible to increase the productivity of the crop rotation link against the background of the embedded wood chips from 13.3 to 19 tons of forage units (FU) per hectare, of wood chaff – from 10.5 to 19.2 t FU/ha, biochar – from 16.1 to 21.4 t FU/ha, ash – from 15.6 to 21.2 t FU/ha while improving product quality. The profitability parameters of technologies for the development of the shrubby idle land based on the data on the cost of yield increase (21–52 %) are 8.8–9.1 times lower than for the additionally produced and sold dairy products (191–459 %). Due to our production and direct sale of high-quality dairy products, the average annual net income from the development of 1 hectare of lightly and heavily shrubby idle land increases from 21 to 205.7 thousand roubles and from 9.7 to 80.5 thousand roubles respectively. With the re-processing of TSV to Eurowood, these indicators increase by 159.2 thousand roubles/ha per year. Due to the relatively high cost of biochar production, the «biochar + complex of ameliorants» option, the best in terms of agronomic and environmental efficiency, is significantly (1.7 times) inferior to agronomically less efficient technologies in short-term studies in terms of profitability (132 % versus 230 %). Less efficient technologies include embedding of crushed TSV in the soil with modern milling machines. The full payback period of biochar technology when calculating income for feed is 3.1 years, for milk and dairy products – 1.3 years.
