Published: December 2022

Abstract
We propose an algorithm for clustering short text fragments such as lists of ingredients in food products using the k-means algorithm in combination with the molecular chemical reactions algorithm. The solution obtained with k-means is used as an initial molecular structure solution to optimize chemical reactions in combination with k-means by generating new solutions using the four main types of chemical reactions. The computational experiment showed the comparative efficiency of new algorithm, taking into account numerical metrics: accuracy, precision, recall, and F-measure.

Published: December 2022

Abstract
Nowadays due of the world population growth, the demand for agricultural products is also growing. To obtain good meat and dairy products, high-quality feed for farm animals is necessary. Legume-gramineous perennial grass mixtures are used to improve fodder lands. Our experience included a test of 9 variants of legume-gramineous grass mixtures, where 6 types of grasses were used: red clover, alfalfa (legumes), meadow timothy grass, orchard-grass, smooth brome-grass, meadow fescue (cereals). The experiments were carried out in four repetitions on the lands of hay and pasture use with the use of fertilizers; there were carried out phenological observations, biometric measurements, and determination of the botanical composition. In herbage from hay fields the smooth brome-grass dominated, and in herbage from pastures the orchard-grass dominated. The proportion of non-sown grass species reaches 26.3-32.7 % in three-component grass mixtures with meadow timothy grass. Meadow fescue and meadow timothy in terms of growth rate, reactions to nitrogen application were inferior to the orchard-grass and smooth bromegrass, which led to their oppression and displacement from the herbage. The best density of plant standing per 1 m2 was noted in the orchard-grass and smooth bromegrass, the smallest - in meadow fescue and alfalfa.

Abstract
The main and economically priority vector of development of agroindustrial complex of the Russian Federation in the current realities is sustainable production of agricultural products in volumes that not only meet the needs of the population, but also create a certain reserve, able to offset the negative effects of forced production downturns and crises. Beef is a high-quality source of protein in human nutrition. In the conditions of protein diet deficiency the question of increasing the volumes of animal production and, in particular, beef as one of the main traditional components of human diet acquires the special urgency. In this connection, we have set the task to study the indicators of beef productivity of Limousin cattle under the conditions of stabling system in a farm located in the biogeochemical conditions of Voronezh region of the Russian Federation. The researches made show that the meat productivity of cattle of Limousin breed differs significantly in pre-slaughter weight of bulls and heifers amounted 621.33 kg and 449.67 kg, and the slaughter weight of steers and heifers was 385.37 kg and 272.30 kg. The slaughter yield of steers was quite high and was 61.98±1.06%, while that of heifers was slightly lower and was 59.90±0.58%. The most interesting is the comparative evaluation of meat quality in interbreed and age aspects according to its dry matter and water content, protein and fat content, as well as other indicators characterizing the product quality, so the ratio between protein and fat in meat, the water-holding capacity of meat proteins were studied to determine the manufacturability and meat quality. Also, indicators characterizing the chemical composition of the longest muscle of the back were determined.

Authors: Ozerova M G , Fedorova M A 
Published: December 2022

Abstract
Sustainable development of food systems is a global challenge for both Russian and world economy. Within each country, the economic, social and environmental aspects of sustainability should be considered in symbiosis when forming conditions for the development of agricultural sectors. Dairy cattle breeding has always been one of the leading sub-sectors of agriculture, the prerogative of which is to provide the population with milk and dairy products in an amount that advises recommended consumption standards. Digital transformation of the sub-sector is considered as an element of the global project in the Ministry of Agriculture of Russia “Digital Agriculture”. The paper presents analytical materials on the level of self-sufficiency and economic availability of milk and dairy products in Russia as a whole, as well as the current state of the production potential of dairy cattle breeding in the Krasnoyarsk region. It was found that the loss of gross milk production due to a decrease in the number of cows compensates for the increase in productivity. It is noted that in Russia the agricultural industries are going through the next stage of serious technological changes, which is associated with the need to modernize production based on the use of information technologies, automation capabilities, digital technologies and platform solutions. This process helps to solve the main task – to ensure the sustainable development of food systems on the basis of increasing the production potential of industries.

Published: December 2022

Abstract
The studies conducted on establishing the impact of introducing various norms of sewage sludge on the yield and nutritional value of agricultural crops when creating an agrolandscape of a reclaimed municipal solid waste landfill were carried out on such crops as triticale, festulolium, awnless brome. The amount of nutrients supplied to the experimental variants depended on the application rate of sewage sludge or soil. No further nutrients were added. The conducted information-logical analysis showed the presence of a direct close relationship between the yield of triticale, festulolium, awnless brome and variants of the field experiment. The share of the influence of the introduction of sewage sludge according to the variants of the experiment on the yield of festulolium was 31.64%. The share of the influence of the introduction of sewage sludge according to the variants of the experiment on the yield of triticale is 54.4%. The share of the influence of the introduction of WWS according to the variants of the experiment on the yield of awnless rump was 77.2%. Based on the result of the information-logical analysis, a model of the influence of the residual sewage sludge on crop yields was compiled.

Published: December 2022

Abstract
The article presents an example of a statistical analysis of agro-climatic factors of crop failure in agricultural plots for the cultivation of rice. It is shown that crop failure is mainly due to a variety of random, independent agro-climatic factors: the sum of active temperatures, the sum of precipitation, soil fertility, etc. Agricultural technology of crop cultivation also has a significant impact on crop failure, which is characterized by the following features: the predecessor, the amount of fertilizer, weeding, the number of days from the bay to the discharge of water, the number of days from mowing to threshing. As methods of statistical data processing, the authors use complex data processing by traditional methods, including comparison of mean values of features, principal component analysis, multiple regression analysis, and discriminant analysis. It is noted that the results of complex processing of the agrotechnical characteristics of plots with different rice yields using the apparatus of one-dimensional and multivariate statistical analysis provide a basis only for identifying general trends, since the agrotechnical system has a high level of complexity. For a deeper and more complete penetration into its essence, an apparatus should be used that can identify and take into account the structural heterogeneity of data about this system.

Abstract

Fusarium oxysporum fungus is the pathogen that causes wilts or root and crown rots on many economically important field crops, causing significant losses to agricultural production. The use of plant extracts to control this fungus is an alternative to synthetic fungicides. Black cardamom (Amomum tsao-ko Crevost et Lemairé), which belongs to the monophyletic Zingiberaceae family, is a valuable medicinal plant in Vietnam. The antifungal activity of black cardamom seed extract has been reported in several previous studies. This study aimed to determine the antifungal activity of black cardamom extracts against the F. oxysporum fungus. The fungicidal effects of black cardamom extracts (including ethanol extract of leaf, seed, rhizome + root, and pseudo-stem) concentrations of 50 and 100 mg/L were investigated. Results indicated that the black cardamom extracts had different fungicidal effects on the growth of F. oxysporum mycelium. A significant inhibitory effect on the growth of F. oxysporum mycelium was obtained using the seed extract at a concentration of 100 mg/L. In addition, in the variant with the use of the extract obtained from the seeds, the lowest indicator of the specific growth rate (m) of the fungus was observed. The antifungal components from black cardamom plant could be used in developing novel fungicides (biopesticides) for the diseases caused by F. oxysporum.

Rare-earth elements in salt lakes of Southeastern Transbaikalia
Authors: Borzenko S V , Usmanov M T 
Published: December 2022

Abstract
It was shown that with increasing salinity of waters, it was determined that concentrations of dissolved heavy HREEs and medium MREEs increase in soda lakes. It was determined that sulfatreduction and secondary mineral formation can influence the migration of lanthanides in lakes. Sulfatreduction leads to accumulation of lanthanides of medium MREEs and heavy HREEs subgroups in lake waters. The content of lanthanides of the light LREE subgroup is controlled mainly by secondary mineral formation. Thermodynamic calculations show that the degree of saturation in parasite CaCe0.95La0.6Nd0.35Pr0.1(CO3)3F2 and bastnesite CeCO3(OH)F is higher in soda lakes than in chloride lakes. The saturation of lake waters with respect to cerium hydroxide III in anaerobic and cerium hydroxide IV in aerobic conditions leads to the formation of negative cerium anomaly in lake waters of the considered lake types. It is shown that the different nature of the formation of soda and chloride lakes is the main reason for different concentrations of REEs in their waters and bottom sediments.

Published: December 2022

Abstract
The article deals with the issues of typification of elements of irrigation systems in land reclamation. When designing irrigation systems it is necessary to take into account measures for the agricultural development of reclaimed lands. The natural and economic conditions of the irrigation area, the characteristics of the irrigation source, the irrigation area and its configuration affect the composition of the irrigation system elements, their location, network design, and in each specific case change the irrigation system. Typical technological elements of irrigation systems allow to design quickly the system taking into account the features. In this regard, a nomenclature of typical technological elements of irrigation systems was proposed, consisting of 6 modules. An analysis of the range of controlled parameters on each module in the design and calculation version was also carried out.

Abstract
This article describes that at the moment the level of the Aral Sea and the volume of water has decreased rapidly. The desiccation of the sea affected the entire region of its former water area as a whole: ports were closed, fishing in industrial volumes stopped, since the salinity of the water increased almost 10 times, and many species of flora and fauna could not survive in dramatically changed conditions. The climate of the Aral Sea has also changed – winter has become colder and longer, and summer has become even drier and hotter. Salinization of unsalted arable lands and further salinization of saline soils increases every year due to wind dust and salt from the Aral Sea and other saline soils. To maintain the fertility of irrigated saline soils, their salinization is washed annually (mainly in autumn and winter). To do this, the lands are inspected and washed away. During the washing process, part of the water is absorbed into the ground and carries away part of the salt. Most of the water leaves the cultivated fields and returns to drainage channels, from which to water supply channels for irrigation of crops, and then to rivers. The distribution of the rate and concentration of salt and sand deposition depends on the height and time above the level, it was determined that a number of positive works were carried out to improve the condition of the soil, its rational use and increase soil fertility, as well as to maintain the fertility of irrigated saline soils, their washing.

Abstract
The paper considers improvements in the irrigation regime of the saz zone of the Ferghana Valley by developing reclamation regimes for irrigated lands. As a result of the research, the inflow of groundwater to the massif, the amount of unproductive evaporation of groundwater, the efficiency of drainage and the main factors determining the favorable reclamation state of meadow soils during irrigation were established. The relationship between the hydromorphic regime of soils and the consumption of water resources has been studied. In this work, a quantitative analysis of the processes of transfer of various ions in soils was carried out and a justification was given for the calculation models of salt transfer for meadow soils; It has been shown that under the conditions under consideration, the assessment of the salt regime of irrigated lands must be performed for not only Cl, but also Na, Ca, and Mg ions.
Agricultural land plot reclamation of citrogypsum sediment pool on Belgorod city territory
Authors: Melentyev A A 
Published: December 2022

Abstract
One of the main society tasks with the rapid development of industry is assigned to nature protection and correct use of natural resources. Therefore, a significant role is put to the hands of land use. Today, the mining industry in the Russian Federation is characterized by huge volumes of mining. The main production is carried out mainly due to the open method of work. The negative consequences of such developments are: taking of large land areas from the economic turnover, their violation in the course of work; changes in hydrogeology and landscapes; development of erosion processes, etc. Thus, as a result of mining operations, the areas of land disturbed by such developments, processing waste and mucks of rocks are rapidly increasing. Moreover, when mucks are formed, unnecessary rocks are mucked, without taking into account their suitability for reclamation, and when creating external mucks, the requirements of rational farming are not always taken into account. As a result, these lands become barren and negatively affect the environment. It follows from this that lands disturbed by open pit mining must be returned to economic circulation with minimal losses and the creation of favorable conditions for the environment. The work relevance lies in the study of work on the land restoration in quarries during their development and extraction of raw materials for construction purposes. Reclamation provides for the restoration of lands disturbed by quarrying, as well as the preservation of the already restored land.

Authors: Bulgakova M A 
Published: December 2022

Abstract
Forest fires are one of the problems that impede the conservation and rational use of national resources, as well as restraining the development and sustainable environmental safety of the forest industry. Damage from forest fires is expressed not only in damage to trees, but also in the destruction of the animal and plant world. In addition, the number of forest fires arising directly near settlements is increasing, which leads to the destruction of residential buildings by the elements, as well as the death of people and pets. Such serious negative consequences predetermine the need to develop urgent ways to improve the activities of law enforcement agencies that ensure the protection and protection of natural resources of the Russian Federation. The purpose of this study is to study the activities of the internal affairs bodies to prevent forest fires and eliminate their consequences. As a result of the study, the author analyzed the dynamics of various indicators and individual measures that reflect the effectiveness of the activities of the internal affairs bodies to prevent forest fires. The author’s principle of forest insurance is practical. The use of the proposed tool will increase the efficiency of government agencies in the process of ensuring environmental safety and eliminating the consequences of forest fires.
