Authors: Zhigulina T N , Kostritsina M N , Luchnikova N M , Lebedeva L V 
Published: October 2021

Abstract
The article considers one of the key aspects of transformations taking place with modern cadastral systems in the context of globalization, integration and digitalization of the surrounding space and economy. It is revealed that the transformation of existing functions of national cadastral systems in the transition to digital economy will obviously lead to the emergence of new properties of cadastral systems, in particular to the emergence of properties of adaptability. The study shows the regular stages of development of the functions of cadastral systems for each time stage, proving that the functions performed by the cadastral system are not static; they change as the economic system of society changes. From the point of view of system conceptions, the development of cadastral system follows a logistic curve and includes the stages: emergence of cadastral system and functions, stabilization of functions, their qualitative development, specialization of functions. Each stage is accompanied by the process of function deployment (winding up) under the influence of the processes taking place in the economic system and society. The emergence of the property of adaptability in the near future of cadastral systems will contribute to the emergence and development of a whole bundle of functions of national cadastral systems, aimed at adapting these systems to the environment of their functioning. The emergence of this new feature is necessitated by the ongoing digital transformation of land-use systems as a response to the challenges facing the global land-use system.

Published: October 2021

Abstract
The article considers the influence of resource-saving technologies in agricultural production during tillage. The possibilities of zero tillage in the conditions of agriculture ecologization are determined. The necessity of using soil protection technologies in connection with the use of tank mixture in the processing of the reference area is justified. The quantitative content of total organic carbon (Sorg), as well as alkaline-soluble and water-soluble organic matter, was estimated. Their share in the structure of Sorg is determined. For the first time in the agricultural zone of the Krasnoyarsk Region, the long-term effect (9-10 years) of zero technology on the dynamics of organic carbon content and its mobile forms was determined. Chemical and physico-chemical indicators relative to seasonality are presented. The degree of mobility of the organic matter of the soil treated by zero technology is determined and the reasons for this fact are revealed. It is shown that the zero technology reduces the degree of mobility of organic matter.

Abstract
The study results on using macro- and micronutrients in the cultivation of white lupine (Lupinusalbus L.) in the soil and climatic conditions of the Central Black Earth region of Russia are presented. Field trials were carried out in 2018-2020 at the Department of Plant Growing, Breeding and Vegetable Growing in Belgorod State Agrarian University. The object of research is a high-intensity variety of white lupine Degas. The subject of research is the Aquamix microfertilizer of two brands – Aquamix-T (for seed treatment) and Aquamix-TV (for foliar dressing), macrofertilizers – potassium sulphate (K2SO4) and potassium monophosphate (KH2PO4). The weather conditions during the years of the experiments were unfavorable for the growth and development of lupine, since during the entire growing season of the plants an increased temperature regime was observed with a deficit of precipitation. The soil cover of the experimental field is represented by typical chernozem with an average content of basic nutrients. The accounting area of the plot is 18 m2, the replication is fourfold, the placement is systematic. The experiment included seven options: 1) control (without fertilizers), 2) seed treatment with Aquamix-T micronutrient fertilizer, 3) seed treatment with Aquamix-T micronutrient fertilizer and foliar fertilization with Aquamix-TV micronutrient fertilizer, 4) seed treatment with Aquamix-Tilist micronutrient fertilizer solution potassium sulphate, 5) seed treatment with microfertilizer Aquamix-Tilist feeding with potassium monophosphate solution, 6) seed treatment with micronutrient Aquamix-Tilist fertilizer with a mixture of Aquamix-TV + potassium sulphate, 7) seed treatment with micronutrient fertilizer Aquamix-Tilist fertilization with potassium monophosphate mixture. Analysis of the data obtained showed that the highest yield of white lupine seeds was obtained on the variants with seed treatment with Aquamix-T micronutrient fertilizer together with foliar dressing with Aquamix-TV micronutrient fertilizer in combination with K2SO4 or KH2PO4 macrofertilizers, which was 3.64 and 3.62 t/ha, respectively, which is 0.64 and 0.62 t/ha or 21.3 and 20.5% above the control variant.

Published: October 2021

Abstract
Lipid oxidation is one of the leading indicators that determine the storage duration of emulsion fatty products. To protect fat and oil products from oxidative spoilage, antioxidants are widely used, the mechanism of action of which is to terminate the reaction molecular chains. As a result of the studies carried out, it was found that physical modification of protein products from sesame seeds (full-fat flour, protein concentrate), used in the production of mayonnaise as a structurant and stabilizer, by treatment with electromagnetic fields of extremely low frequencies, makes it possible to increase the resistance of the finished product to oxidation.

Authors: Demin E A , Barabanshchikova L N 
Published: October 2021

Abstract
The research was carried out in order to establish the effect of mineral fertilizers on the nutrient’s dynamics in corn crops. The experiment was carried out from 2016 to 2018 in Zavodoukovsky district of the Tyumen region. The experimental scheme provided for the option without using mineral fertilizers and with the introduction of NPK for the planned yields from 4.0 to 6.0 t/ha of corn grain. In the experiment, a hybrid Obsky 140 was sown; the seeding rate was 70 thousand plants per hectare. It was found that the introduction of mineral fertilizers provides an increase in the content of nitrate nitrogen by 20-25 mg/kg of soil; mobile phosphorus by 9-48 mg/kg. The studies revealed that one kilogram of the active ingredient of nitrogen fertilizers increases the NO3 content in the soil by 0.17 mg/kg; a kilogram of phosphorus fertilizers in the active ingredient increases P2O5 by 0.30 mg/kg; a kilogram of potash fertilizers in the active ingredient increases K2O in the soil by 0.33 mg/kg. During the growing season of maize, the content of nitrate nitrogen, mobile phosphorus, and potassium in the soil in the control decreases to 5, 58, and 93 mg/kg, respectively. On fertilized options, the decrease in nitrate nitrogen and phosphorus is less – 12-14 and 59-69 mg/kg. Whereas potassium decreases more significantly – 69-92 mg/kg.

Published: October 2021

Abstract
The purpose of the study is to identify the municipalities of the Altai region, which is one of the leading agrarian regions of Russia, with the development potential for cooperation of small forms of farming in dairy cattle breeding. It was found that in conditions of a decrease in the number of cows in all categories of management, the proportion of municipalities in the region that have the highest and high potential for the development of consumer cooperation increases (in 2007 this group included 54.0% of all municipalities of the region, then in 2020 more than 69.8%). However, this potential has not been realized, which significantly reduces the possibility of stabilizing and increasing milk production in the region. It was concluded that consumer cooperation develops only with government support and by proactive entrepreneurs. In the areas with suitable agrarian infrastructure for the pooling non-profit associations of milk producers, the necessary infrastructure, organizational and educational conditions should be developed.

Published: October 2021

Abstract
The agribusiness sector has great importance in the economy, and in order to remain competitive, the number of investments in disruptive technologies and concepts, such as Internet of Things, Physical Cyber Systems, Artificial Intelligence, among others, grows. These concepts are often applied by agribusiness startups, known as Agritechs. To help these startups spread their technologies, and mitigate their high mortality level, the use of a maturity model is a good tool, as maturity models help to identify factors that need to be worked on and improved. The creation of a maturity model for Agritechs is innovative, which makes the definition of possible maturity models to be used as a basis challenging. Thus, this article seeks to present the core constructs related to Agritechs in order to identify possible maturity models that can be used as a steppingstone in creating a new maturity model, specific to Agritechs. To reach this goal, the bibliometric analysis software, SciMAT, was used, to define the most relevant themes for the area of Agritechs, so that, based on these themes, it is possible to more properly research maturity models relevant to the definition of dimensions, basis of an Agritechs maturity model. The results showed that maturity models in sustainability, industry 4.0 and startups should be combined and adapted to develop a maturity model specific for Agritechs. The initial dimensions developed for this model were: Change management dimension, Strategic dimension, Technological dimension, and Sustainability dimension.

Abstract
Currently, digitalization is the most urgent problem faced by many agricultural producers, so the main trend in the development strategy of the Russian Federation is digitalization. The goal of this direction is to introduce and improve the use of new technologies in all spheres of national life. Agriculture in the Russian Federation has always been one of the most important areas of the economy, so technological development is very important. “Digital agriculture” will help find and make the best decisions not only for the growth of the company, but also to prevent various inefficient decisions that lead to future bankruptcies. The emphasis on the development of agro-industrial and industrial complexes has once again proved the importance of this sector of the economy for the state. In this article, the authors try to understand the current strategy for the development of agriculture until 2025 and what role digitalization plays in it. According to the authors, the implementation of such solutions and their adoption by companies not only control the development, but also provide a good tool for improving the efficiency of the agricultural sector.

Published: October 2021

Abstract
The paper presents an analysis of nonparametric methods for assessing the comparative efficiency of agro-industrial enterprises. The authors analyzed Data Envelopment Analysis, Free Disposal Hull Analysis and Productivity Index. The most important characteristics of the models are highlighted, which are used to compare the methods. The preference was given to the DEA method, since the other described methods and their modifications do not allow taking into account the factors influencing the efficiency of agricultural enterprises. In particular, the factor of the territorial location of the enterprise. But it is the climatic zone of the location of the enterprise that has a significant impact on the efficiency of agricultural activities. When implementing the assessment method, it is necessary to take into account the fact that climatic conditions, depending on the geographical location, are always different.

Abstract
The article presents the results of the analysis of animals of the Bredy meat type by the allele fund of erythrocyte antigens of blood groups and DNA - polymorphism of the GDF5 and TG5 genes, which are valuable for beef cattle. The studies were carried out on the basis of blood analysis of cows from three micropopulations belonging to well-known breeding enterprises in Russia. Alleles of blood groups were identified for all systems, and the frequency of their occurrence was shown. The work focuses on the ratio of homozygous and heterozygous genotypes, shows the degree of their displacement depending on the micropopulation, determines the indices of genetic similarity (I) and genetic distance (Dn) between micropopulations. The revealed levels of polymorphism of animals of the Bredy meat type for genes GDF5 and TG5 showed an insignificant frequency of occurrence of the desired genotypes, this indicator for the first gene was 8.7, and for the second - 4.3%. Comparison of the frequency of occurrence of the most common alleles of the EAB-system of blood groups of the herd, with the frequency of occurrence of genotypes for genes GDF5 and TG5 in a random sample of cows of the Bredy meat type, did not show any dependence of the polymorphic state of genes on the specific content of alleles.

Published: October 2021

Abstract
The demand for sheep products these days becomes higher, as evidenced by the tendency to increase small ruminants in the world and Russia. It leads to manufacturers’ desire to get products as quickly as possible, without worrying about their quality. Various medications are used, which later, when eating animal meat, can have a detrimental effect on the human body. These studies aimed to study the effect of low-intensity laser radiation on the sheep’s organism and obtain ecologically clean and high-quality mutton. For this, during the experiments, the blood of animals was studied. An essential role of protein metabolism in the animal body is blood serum proteins, qualitative and quantitative characteristics. They are the primary plastic material of tissues and organs and carry out regulatory, catalytic, and immunobiological functions. The growth rate is closely related to protein deposition. Individual development is determined by the constant exchange of substances and energy between the body and the external environment. However, each animal species has its metabolic traits, and, in particular, it concerns the transformation of proteins. Age-related biochemistry of protein metabolism has significant material in disclosing the fundamental biochemical constants of metabolism in animals’ bodies. Simultaneously, the study of the peculiarities of protein metabolism is one of the main links in the knowledge of the biochemical essence of each period of sheep’s life.

Abstract
In Sverdlovsk region Holsteinized black-and-white cattle of the Ural type are being bred. This type of cattle is represented by numerous, highly productive animals with a high genetic potential for productivity. The aim of this article is to study the correlation of age of the first insemination of heifers on their economically useful traits. It was found that the age of the first insemination directly affects the milk productivity of Holsteinized black-and-white cattle of Ural type. The difference in age of the first insemination between the groups was 2.7 months, or 18.6%. The difference of productive period longevity between the groups was also observed, which was 0.21 of lactation (6.7%) in favor of the group that got its first insemination at age of 16-18 months. Cows inseminated for the first time at an earlier date featured lower parameters of milk productivity: lower milk yield for life, lower milk yield for the first lactation and for maximum lactation. The difference was significant at P≤0.01 in favor of cows which underwent the first insemination at age of 16-18 months for life-long milk yield. A significant difference in MFP in milk was revealed in favor of the cows in the first group (the period of the first insemination was 14-15 months). It was 0.09% at P≤0.01. The difference in MFP in milk did not have a considerable influence on increase of nutrients yield in milk, in particular milk protein. The duration of the period between calvings and the service period was long in both groups of cows, which allows concluding that, regardless of the age of first insemination, the decrease in reproductive capacity in cows of modern Holsteinized black-and-white cattle is observed. This is proved by the record KVS – 0.87 - 0.88.
