Authors:   Research Institute of Agriculture of Crimea, Ptashnik O.P.
Published: November 2021

Due to the lack of irrigation, the question of replacing soybean with an equivalent crop in the context of nutritional value and adaptation to the weather conditions of Crimea arises. One of such crops can be white lupine (Lupinus albus L.). The purpose of the research was twofold: assess L. albus productivity and crude protein content in grain; identify the most promising varieties and breeding numbers of white lupine under conditions of the steppe Crimea. In 2016-2018, the research was carried out on the experimental field of the Research Institute of Agriculture of Crimea according to the B.A. Dospekhov methods of field research and methodology of the State variety testing of agricultural crops. We studied the influence of bioclimatic conditions of the steppe Crimea on the growth, development, grain yield formation and protein content of four varieties (‘Michurinsky’, ‘Alyi Parus’ (standard), ‘Dega’ and ‘Desnyansky 2’) and four promising breeding numbers (‘CH-1022-09’, ‘CH-1677-10’, ‘CH-1397-10’ and ‘CH-6-11’). A wide diversity of weather conditions during the years of research made it possible to evaluate the samples in favorable and stressful conditions. In drier years, the growing season lasted 93–97 days because of the reduction in interphase periods; in milder ones it was101 days. The results in grain yield have been mixed: from 0.48 to 1.45 t/ha in 2016; from 0.35 to 0.56 t/ha in 2017; from 0.39 to 0.54 t/ha in 2018. On average, over a three-year study, breeding numbers ‘CH-1022-09’ and ‘CH-1677-10’ were the most productive. Their yield was 0.65 and 0.81 t/ha, respectively. In 2017, crude protein content varied from 24.02 to 28.49%; in 2018 – from 26.05 to 31.1%. On average, over the years of study, the highest protein content was typical for the varieties ‘Alyi Parus’ (29.30%) and ‘Michurinsky’ (29.03%). Breeding numbers ‘CH-1022-09’ and ‘CH-1677-10’ were distinguished by the highest indicators of productivity and yield; in terms of crude protein content, varieties ‘Alyi Parus’ and ‘Michurinsky’ were the best. Consequently, they are the ones that are recommended for cultivation.

Sugar beet (Beta vulgaris L.) is one of the most important industrial crops, which is the main raw material for sugar production – a product of strategic importance widely used in food and pharmaceutical industries. In this regard, the provision of domestic beet growing with seeds of domestic hybrids that are competitive with the best foreign ones is particularly relevant. The purpose of the research is to study the effect of the basic mineral fertilizer and microelements boron and zinc on the sugar beet seeds yield, structure and quality indicators. The studies were carried out in the experimental fields of the All-Russian Scientific Research Institute of Sugar Beet and Sugar named after A.L. Mazlumov, located in the zone of unstable moistening in the Central Black Soils region in the northwestern part of the Voronezh region (Ramon village). The soil of the experimental site is represented by leached hard loamy chernozem with a medium humus content of 4.5 %. Field experiments were laid in 2018–2020 according to the methodology of B. A. Dospekhov. The experiment scheme included the following options: control (without fertilizers); double foliar feeding of seed plants with a 0.1 % solution of a mixture of boric acid and zinc sulfate before the flowering; N160P160K160; N160P160K160 + foliar feeding. Laboratory analyzes of seed quality were carried out according to GOST 22617.2 – 94. The data obtained indicate a significant effect of the basic fertilizer (N160P160K160), which contributed to a 0.53 t/ha (45.3 %) yield increase compared to the control. The sowing qualities of seeds also increased significantly: germination energy by an average of 10.3 % abs., germination – by 9.8 % abs., good quality – by 5.4 % abs. Foliar dressing with microelements had practically no effect on the yield; however, it provided a significant increase in the indicators of the sowing qualities of seeds: germination energy – by an average of 3.3 % abs., germination – by 4.7 % abs., good quality – by 4.6 % abs. Direct dependence of the value of the yield of seeds on the constituent elements of the structure was also revealed: the type of bush of seed plants, the number of productive shoots, their height and seeding per unit length. The correlation coefficient (r) for all three paired dependences of the quantities was 0.99.

Currently, the search for biological agents that are alternative to chemical ones to protect agrocenoses from weeds, including quarantine objects like different types of ragweed, is relevant because they cause biological and technological damage to the environment, agriculture and have a negative impact on human health. The research was aimed at searching for biotically active elicitors of plant and microbial origin for the induction, reinforce of oxidative stress and inhibition of Ambrosia artemisiifolia L. growth. Strains were searched for and studied in 2019–2020 in laboratory experiments and greenhouse trials in the Research Institute of Agriculture of Crimea. Ragweed plants were grown in pots. Soil – chernozem southern. In the phase of 4–6 leaves, plants were treated with biorational preparative forms based on microbial and plant elicitors at a dose of 200 mkl/plant. For bioherbicidal composites, strains-inhibitors from the Research Institute of Agriculture of Crimea collection (CCM), plant extracts from the ragweed and glycerin were used. The inhibition efficiency was evaluated three weeks after treatment. The indices of height, phytomass, antioxidant status and ragweed damage degree were taken into account. We identified seven strains that inhibited plant growth by 0.13–1.08 g/plant (37–38 %) compared to the control variants: 1) water treatment, 2) bacterization with a phytopathogenic strain of Stagonosporopsis heliopsidis from the All-Russian Scientific Research Institute of Plant Protection collection. For the first time, we used ambrosia BAS to develop a birational herbicide to control the ragweed. Bacterization with biorational preparative forms based on biotically active elicitors of plant and microbial origin affected the homeostasis of ragweed, induced plant stress by blocking the enzymatic activity and the antioxidant protection systems. The activity of catalases and polyphenoloxidases decreased by 2.9–85.6 and 1.2–658.0 times, respectively, with a significant correlation between themselves (r = 0.66) and the correlation of catalase activity with plant phytomass (r = 0.72). The content of glutathione decreased by 2.5–2.7 compared to the control and had significant correlations with the activity of catalases (r = 0.63) and the phytomass of ragweed (r = 0.80) (p < 0.05) depending on the components of the biohebicidal formulations.

Nowadays, hemp production places high demands on the efficiency of breeding and the reliability of seed multiplication of hemp (Cannabis sativa L. subsp. Sativa). Therefore, a detailed study of genetic polymorphism, intervarietal and intravarietal variability, and the peculiarities of the formation of the fund of available genetic diversity of culture becomes urgent. The aim was to study the genetic polymorphism of some modern Russian species of industrial hemp using molecular ISSR markers. Experimental data were obtained in 2021 in the laboratory of molecular-genetic researching and cell selection of the Federal Research Center of Bast Crops. We studied ten varieties of hemp of Russian breeding from the collection of Penza Unit of Federal Research Center for Fiber Crops: ‘Milena’, ‘Vera’, ‘Surskaya’, ‘Nadezhda’, ‘Ingreda’, ‘Diana’, ‘Juliana’, ‘Gentus’, ‘Dimra’, ‘Margo’. DNA was isolated from individual seeds by the CTAB method. When setting up PCR, 20 ISSR primers were used; amplification products were separated in agarose gel. A total of 99 alleles of 430–1500 bp were identified, the genetic profile of each studied sample turned out to be individual. Cluster analysis and genetic similarity dendrogram construction made it possible to reveal the presence of intra- and intervarietal genetic polymorphism, visualize the phylogenetic relationships of the studied species. The studied samples formed dense intravarietal groups and were divided into three intervarietal clusters. The presence of similar components of crossing in the pedigrees of the studied varieties is associated with the peculiarity of the identified clustering and determines the prerequisites for the formation of the genetic narrowness of modern varieties of cannabis. The set of 20 used ISSR-markers is distinguished by good resolution for studying the genetic polymorphism of hemp. Intravarietal polymorphism with an average genetic distance of 0.14 and intervarietal polymorphism with a distance of 0.61 were revealed in 10 cultivars of hemp of the Central Russian type. According to the results of cluster and factor analyzes, which showed the similarity of conclusions, the samples were divided into three main clusters, mainly differing in the originator of the variety. The study of DNA polymorphism of seeds of the ‘Diana’, obtained after reproduction of two years, indicates its genetic stability.

Published: November 2021

Spontaneous spinal epidural hematoma (SSEH) is a rare disease but may lead to life-threatening consequences if not timely diagnosed and managed. Emergent hematoma evacuation is indicated before neurological deficits become irreversible. We report two cases. The first case was a 45-year-old man brought to hospital because of an acute onset of quadriparesis and urinary incontinence. His cervical magnetic resonance imaging (MRI) showed an epidural hematoma at the C5-C6 level with severe spinal cord compression. He underwent an emergency C5-C6 right hemi-laminotomy to remove the clot and decompress the cord. Postoperatively, his left-sided deficits immediately resolved. His urinary function returned to normal two weeks after the surgery. He could independently walk two months later. The second case was a 57-year-old man admitted to the hospital because of severe neck pain and paresthesia in both arms. He had been using an antiplatelet for two months. His MRI revealed an epidural hematoma from C2 to C4 with spinal cord compression on the right. This patient was successfully treated with conservative treatment. If SSEH is left undiagnosed and untreated, the neurological deficits may be permanent. Early emergent hematoma evacuation contributes to a favorable outcome. Conservative management is reasonable if neurological deficits are not severe.

Ceroid neuronal lipofuscinosis (CLN) is a rare group of autosomal recessive neurodegenerative diseases that cause developmental delay and seizures. Herein, we present a case of a 7-year-old girl who referred for magnetic resonance imaging (MRI) following cognitive impairment and seizures. MRI was performed demonstrating some usual findings, and, surprisingly, a normal-sized cerebellum. This case draws attention to not hold to just the classical imaging presentation in order to suspect some leukodystrophy.
Migraine Headache as a Presenting Feature of Multiple Sclerosis: A Case Report

Published: November 2021

Multiple sclerosis (MS) is a chronic inflammatory disease, causing neuronal demyelination and axonal damage in the central nervous system. Symptoms of MS vary widely because of different grades of sensory, motor, and cognitive dysfunctions. Although headache as the initial symptom of MS is rare, it is a common comorbidity that affects most patients. However, it is unclear that the headache manifestation in newly diagnosed people with MS should be considered as an MS attack or merely a comorbid condition. We report the case of a 31-year-old woman with newly diagnosed MS who presented with exacerbation of headache episodes without any abnormal neurological exam findings. The headaches did not respond to nonsteroidal anti-inflammatory drugs and triptans. After administration of methylprednisolone, the headaches were significantly improved, and during 3 months of follow-up receiving glatiramer acetate, no episode of headache has occurred. This case demonstrates the possible relationship between migraine and MS in newly diagnosed patients. New-onset headaches, a change in the pattern of previous episodes, and inadequate clinical drug response to headache treatment should all be taken seriously and warrant further investigation. Thereby, early diagnosis and proper treatment for patients with MS could improve their quality of life.

Published: November 2021

Introduction: Numerous studies have shown that clinical evaluation in labor is not very accurate, therefore ultrasound is one of the instruments that can give us a more objective assessment than the clinical evaluation. Objectives: In this study, we investigate the magnitude of the angle of progression (AoP) at the second stage of labor in fetuses with cephalic presentation and its relation to spontaneous vaginal delivery. Patients and Methods: In this cross-sectional study, we measured the AoP using trans-perineal sonography in the 2nd stage of the labor and compared AoP in normal vaginal delivery (NVD), cesarean and NVD with vacuum groups on 80 pregnant women. We also investigated the correlation between AoP and induction time and duration of the second stage of labor. Results: In 80 study patients, 54 (67.5 %) had normal vaginal deliveries, 21 (26.2 %) had cesarean section and 5 (6.2%) had NVD with a vacuum. There was a statistically significant difference between NVD, cesarean section, and NVD with vacuum in terms of the AoP (P<0.01). There was a statistically significant correlation between AoP and induction time, duration of 2nd stage of labor and Apgar scores (P<0.05). Conclusion: Higher progression angle is associated with shorter induction time and 2nd stage of labor, higher neonatal Apgar scores and a higher chance of spontaneous vaginal delivery which makes it an appropriate index for predicting pregnancy outcomes.

Published: November 2021

Introduction: Surgical site infection (SSI) is caused by cesarean section in the hospital and its prevalence in the studies is up to 16%. Objectives: This study aimed to compare the rate of infection in women undergoing cesarean section. Oral clindamycin and cefalexin were administered for 48 hours as prophylactic antibiotics. Patients and Methods: In this clinical trial study, women with emergency cesarean section were divided into two groups. Intervention was oral administration of cefalexin 500mg every 6 hours and clindamycin 300 mg every 6 hours for 48 hours. All participants were referred to the gynecology center on day 7–10, at the time of removal of the sutures, and within 30 days after cesarean section, to assess the presence or absence of wound infection after surgery during 30 days. Results: In this clinical trial study, 462 pregnant women undergoing cesarean section were enrolled in the intervention and control groups. Of 231 patients in the intervention group, 15 women (6.5%) had cesarean section infection (13 cases with superficial, and 2 cases with deep infection). In the control group, 45 cases (19.5%) had cesarean section infection (31 cases with superficial, 10 cases with deep, and 4 cases with developed pelvic infection) (P = 0.001). Age, pre-cesarean length of stay, pre-term incision, type of incision, discharge longer than 18 hours after cesarean section, and maternal diabetes were significantly different regarding cesarean section infection in both groups. The frequency of cesarean section infection was less in the intervention group (P <0.001). Conclusion: Administration of prophylactic antibiotic can have a significant role in reducing cesarean section infection. Trial Registration: Registration of trial protocol has been approved in Thailand registry of clinical trials (identifier: TCTR20201204002, http://www.clinicaltrials.in.th/index.php?tp=regtrials & menu=trialsearch & s-menu=fulltext & task=search & task2=view1 & id=7120, ethical code; IR.UMSU.REC.1397.323).
Asprosin; effects and associations

Published: November 2021

Asprosin is a hormone that is released by the white adipose tissue. It stimulates the release of glucose, which is produced in the liver, into the blood. Asprosin targets many organs including the skeletal muscle, pancreas, liver, and cardiac system. In addition, asprosin stimulates appetite leading to weight gain. It also influences glucose metabolism, cell apoptosis, and insulin resistance. Furthermore, it has been implicated in some medical conditions such as obesity and diabetes.

Published: November 2021

Introduction: Diabetic nephropathy (DN) is the leading cause of chronic kidney disease in diabetes patients. The angiotensin AGT M235T gene polymorphism, which is linked to the renin-angiotensin-aldosterone system (RAAS), has been extensively studied in DN patients, but the results are still conflicting. The current study’s goal is to conduct a meta-analysis to assess the relationship between AGT M235T gene polymorphism and DN susceptibility. Methods: Fourteen case-control studies related to AGT M235T polymorphism and DN were searched using PubMed, Web of Science and Google Scholar databases. Genotype data from the T2DM and T2DN groups were collected from all papers. The pooled odds ratio (OR) and 95 percent confidence interval (95% CI) were calculated employing a random-effects model to assess the relationship. Results: There were no statistically significant link between AGT M235T and DN risk in dominant (P=0.801, OR: 0.95; 95% CI: 0.66-1.38), allelic (P=0.933, OR: 1.01; 95% CI: 0.75-1.37) and recessive (P=0.374, OR: 1.21; 95% CI: 0.80-1.83) genetic models. Further, the stratified analysis based on ethnicity did not reveal significant link between AGT M235T and DN risk in Asian (Dom OR: 1.07; 95% CI: 0.63-1.82) and the Caucasian populations (Dom OR: 0.77; 95% CI: 0.49-1.21). In all three models, there was a high degree of heterogeneity between studies. Publication bias was not seen. Conclusion: Our findings suggest that the AGT gene M235T polymorphism does not contribute to DN risk. However, validation of this association will require multi-center and large population-based studies.

GIS-analysis of the old-developed region’s land use structure for the purposes of ecological framework design (on example of the Belgorod region)
Authors: Luzhkov Roman , Pakina Alla
Published: November 2021

The Belgorod region is an example of an old-developed region, continuing to experience intense anthropogenic pressure. There are almost no undisturbed landscapes within the boundaries of the region, which have no restrictions to be included into the regional network of protected areas according to their ecological characteristics and legal status. The problem is that the ecological framework of the region is not a functionally and territorially integrated system, which is necessary for its effective functioning. The solution of the problem could be implementation of the scheme of ecological framework, developed in 2007 as a part of the territorial development of the region, but it is associated with potential conflicts of land owners rights. In this regard, the paper analyzed the compliance of the ecological framework proposed scheme with the existing land use structure to assess the prospects its practical implementation.

The analysis of the anthropogenic pressure on the municipalities of the Belgorod region allowed to identify the model districts (Borisovsky and Gubkinsky) with the maximum and minimum anthropogenic pressure. On the example of selected areas, the prospects of transferring areas within the boundaries of the proposed scheme to the category of protected lands, corresponding to the structural elements of ecological framework were evaluated. The land use structure of the model districts was analyzed using OpenStreetMap resource which allowed to identify the main land categories (settlements, industry, forestry and agricultural lands and protected areas) and differentiate them by the potential of compliance with the proposed framework scheme. Processing the data of various categories lands spatial distribution within the boundaries of the ecological framework in the Borisovsky and Gubkinsky districts using the Quantum GIS program showed that despite the high pressure on the territory it is still possible to implement the proposed scheme. The design of the ecological framework in the old-developed regions should be carried out at the level of municipalities. The conducted research also confirmed the relevance of the legislative framework improvement to ensure environmental protection activities by fixing the legal category “ecological framework”.
Application of areal interpolation methods when determining zones of potential fertility of soils of agricultural lands
Authors: Klebanovich Nikolay , Kindeev Arkady , Kizeeva Vitalina
Published: November 2021

The article presents one of the possible options for improving the methodology for identifying zones of potential soil fertility. The necessity of using areal interpolation as the only method of geostatistical analysis that takes into account the area of input objects is proved. To check the data for a Gaussian normal distribution, it is necessary to use several verification methods, since when evaluating only statistical parameters, significant (in the case of phosphorus, abnormal) deviations were found, however, when evaluating histograms and quartile-quartile plots, it is necessary to bring the data to a normal distribution was relevant only for humus and phosphorus. The main advantages and disadvantages of the areal interpolation method are shown. With a significant deviation from the normal distribution, in the absence of built-in functions for automated reduction of data to the Gaussian distribution, one of the few ways can be the logarithm of the data. After zoning, it is necessary to perform a reverse translation to the original values for a representative visualization of the results. As a result of the selection of theoretical semivariograms-deconvolutions, the degrees of spatial dependence and optimal distances for the studied properties are determined. It is clear that the lag of acidity and potassium content is 1000 m and 1050 m, respectively. For phosphorus, it is 1300 m. For the humus content, the lag is much lower—440 m. The maximum autocorrelation distance is typical for potassium and humus—2330 and 1528 m; the minimum for phosphorus is 637. The reliability of the cartograms of agrochemical properties is confirmed by the calculated root-mean-square errors. The deviations of pH values are in the range of up to 0.15 units. The highest mean square error of interpolation is observed in weakly acidic soils. The error in the interpolated values of humus from the initial data is inherent in anthropogenically transformed soils. The root-mean-square error of phosphorus values can be estimated as insignificant. The largest errors in K2O—in isolated cases, they reach 120 mg/ha in the central and eastern parts of the region. The resulting map of potential soil fertility was used to determine the relationship with the granulometric composition of soils. A low level is observed on sandy and sandy loam soils, a high level—on loams. Also, the productivity is affected by the relief of the territory—in the dissected areas, productivity is lower than on the plains.

Authors: Badina Svetlana , Babkin Roman
Published: November 2021

This article introduced an assessment of the Moscow population vulnerability to natural and man-made hazards, taking into account the actual population size and its movement within different time cycles (daily and weekly-seasonal). The use of alternative information sources, allowing to obtain more detailed information about the state of socio-geographical systems, correlates with modern international approaches and corresponds to global trends in the methodological approaches modification to solve a wide range of issues. In this work, in addition to official statistical sources, we used data from mobile operators, which make it possible to characterize the localization of subscribers at a certain point in time with the maximum degree of reliability. This made it possible to significantly correct and clarify the currently existing ideas about the distribution of the population over the Moscow city territory. A series of maps has been created that demonstrate population density as a key vulnerability indicator in the context of Moscow municipalities according to Rosstat data and mobile operators information (at the beginning of 2020). In order to identify the discrepancy between the data on the statistically recorded and real existing population, an existing population assessment in the areas of potential technogenic impact of Moscow potentially dangerous enterprises was carried out. As a result of the study, it was shown that in terms of the natural hazard level, urban space differentiation is less pronounced than in terms of the technogenic hazard level. Technogenic hazards endanger the life and safety of not only the traditionally environmentally unfavorable city parts but also a number of prosperous and prestigious districts. It was found that the number of citizens in the zones of the most dangerous enterprises potential impact varies widely throughout the year—from 0.6 to 1.3 million people (on average it is 1 / 10 from all capital residents). These calculated results are much higher than official documents shows.
Changes in the hydrographic characteristics of rivers in steppe agrolandscapes over the past decades (on the example of the Beysug river, Krasnodar territory)
Authors: Pogorelov Anatoly , Lipilin Dmitry , Kiselev Evgeny
Published: November 2021

In the Krasnodar territory, agricultural land occupies 62 % of the territory; of which 79 % is arable land. Most of the agricultural land is located on the Azov-Kuban Plain in the northern part of the region in the steppe river basins. The basin of the Beysug river with an area of about 6,000 km2, in terms of its geographical characteristics, should be attributed to representative basins from the standpoint of the modern dynamics of agricultural landscapes and transformations of the river network. The article analyzes the changes in the steppe agricultural landscapes in the Beysug river basin for the period 1999–2020 in terms of changes in the structure of land use and hydrographic characteristics, based on the data of satellite images.

The transformation of agrolandscapes is accompanied by redevelopment of the territory, massive construction of dams on rivers, violation of the conditions of natural drainage, which leads to the restructuring of water exchange processes in river basins. Changes in water exchange processes under semi-arid conditions can be sensitive to local landscapes and agriculture. Until now, insufficient attention has been paid to the hydrological aspects of the transformation of steppe landscapes. According to the DEM ASTER GDEM, 15 river basins were identified with the subsequent determination of land use types on the surface of the basins. In each of the basins, a land use structure has been established, which directly affects the hydrographic indicators, and a decrease in the length of watercourses and the density of the river network has been revealed. Over the past 20 years, in the studied basins, the total length of watercourses due to plowing and redevelopment of the surface has decreased by 8–37 %, and in general in the Beysug river basin—by 469 km.

The article presents and summarizes the results of mapping transformational processes in the demographic and ethno-confessional space of the Crimea. Map plots reflect the options for visualizing data on demographic, ethnic and religious processes in the Republic of Crimea and the city of Sevastopol over the past decades.

The maps illustrate the dynamics of the population size and density, its natural movement, the balance of migration, marriage and divorce, territorial features of the settlement of large and small ethnic groups of the Crimea, the placement of religious buildings and religious communities on its territory. Maps of rural settlement and the appearance of villages with endangered populations were created and analyzed. The types of dynamics of demographic, ethnic and confessional situations in the Crimea are determined. The analysis of the peculiarities of the dynamics of the ethnodemographic space of the Crimea during the change of its political subjectivity is carried out. The main spatial patterns of the processes that form the modern portrait of the population of the Crimean Peninsula are revealed.

The conclusion is made about the possibility of cartographic study of the demographic and ethno-confessional specifics of the territory after preliminary differentiation of socio-cultural processes within its boundaries into large-scale and local ones. This allows us to clarify not only the spatial, but also the essential markers of their occurrence. In modern Crimea, large-scale transformational socio-cultural processes should include all the reproductive and migration changes that are the result of demographic breakdowns that began in the 1990s. The processes of changing its ethnic and confessional spaces should be considered local in Crimea. Their mapping revealed the narrowing nature of such a phenomenon as the polyethnicity of the territory of the Crimean Peninsula.

Cartographic study of socio-cultural processes in the Crimea confirmed the author’s hypothesis that the Crimean regional community has not completed the process of post-Soviet transformation and continues to support the development trends established at the end of the twentieth century.

The main research topic is the theoretical justification of integrated regionalization of rural areas to optimize the use of natural agro-potential by developing conceptual frameworks and new methodological approaches to assessing the effectiveness of its use and determining environmentally and economically options for the interaction of natural and production-territorial systems.

The problem of creating a theoretical (conceptual) model of integrated regionalization of rural areas using modern geographical methods and GIS technologies to optimize the use of natural agro-resource potential is arisen.

The object of study is the natural agropotential of Smolensk region. Considering the complexity character of research we used the model area.

The aim of the study is to assess the relationship of the spatial soil’s distribution and relief. For this aim, the model area on the territory of Smolensk region was chosen, digital model was created and analyzed.

The research results have independent scientific interest and optimize the using of the natural agro-resource potential. The development of theoretical and methodological aspects of agricultural zoning is the most current problem of modern geography. The solution to this problem is necessary to develop recommendations for agricultural management.

At the present stage of development of agriculture in Russia with extremely limited material, labor and financial resources, overcoming of the agrarian crisis will be possible on the basis of more efficient using of the natural potential of the territory.

For the first time, the correlation of the spatial distribution of soil cover depending on the relief was studied using the model area of Smolensk region. The series of diagrams with the distribution of soil types by height, the distribution of the prevailing soil types on the slopes of different exposures, distribution of the prevailing soil types on the slopes of different angles have been constructed.

The agricultural use of land resources in the dry steppe regions of Northern Kazakhstan has undergone significant changes over the past century and continues to change at the present time. The middle position in the region is occupied by the Akmola region, one of the leading agricultural regions, where 9.3 % of the country’s gross agricultural output is produced. The main branches of agriculture in the region are grain farming and dairy and beef cattle breeding. The study of the change in the ratio of the areas of arable and pasture lands, the changes that have occurred in the state of agricultural landscapes as a result of long-term use is important for the further development of the agricultural industry in the region. Using the example of the Astrakhan district of the Akmola region, typical for the dry steppe zone, an analysis of changes in the structure of agricultural land from 1953 to 2020 was carried out. with the help of a series of digital maps compiled from detailed maps of scientific reference atlases of Northern Kazakhstan in 1964, 1970, remote sensing data of different times, archival materials and data of modern statistics. The resulting maps visualize significant changes in cropland areas within the study area over the past 70 years. Seven main periods were identified, during which the most significant changes in the structure of land use occurred as a result of political, economic and natural factors. During the years of development of virgin and fallow lands, the highest rates of increase in arable land were observed, which continued on a smaller scale until 1990. The period from 1991-1999 characterized by a large-scale reduction of arable land and abandonment of pastures. This was followed by two periods of gradual restoration of the use of arable and rangelands. Compiled comprehensive map of the dynamics of agricultural land use from 1988 to 2020 made it possible to identify spatial and temporal patterns in changes in the structure of agricultural land use, to determine to which specific natural types of lands the abandoned lands belonged and to which restored ones. Spatial analysis showed that over the past 30, more than half of the area’s area has not changed the type of land use. The results obtained are used to select the optimal ratio of arable and pasture lands in the structure of agricultural land use, as well as to develop a strategy for the rational use of agricultural land in the zone of risky farming.
GIS support for monitoring agricultural land in the land management system (on the example of the Volgograd region)

The lack of an up-to-date cartographic basis leads to uncontrolled land turnover, does not reflect their real state and use, thereby leading to the destruction and degradation of not only individual components of the agricultural landscape, but also entire natural systems. Agrolandscape is a complex ecological system that, under harsh conditions of consumption, loses its ability to self-repair and regulate for a very long time. And each of its components needs to be accounted for, monitored, and protected. Geoinformation monitoring ensures the sustainability of both individual components and the entire agricultural landscape, contributes to the formation of effective agriculture and land use, increases the productivity of land and prevents the development of degradation processes. Monitoring of the territory of the Kislovsky rural settlement of the Bykovsky district of the Volgograd region according to 2004 data does not reflect the actual state and order of use of agricultural land and forest resources. The boundaries and areas of dehumified land have changed, and within the boundaries of the forest fund, according to Roseyestr, there are land plots with cadastral numbers ZU 34:02:010001:185, ZU 34:02:010001:104, ZU 34:02:010001:100, with an area of 2.7 hectares each for agricultural production. The area of forest areas has decreased from 576 ha to 484 ha or 16 %, the humus content in the soils is low—1.7 %, which is critical in the agro-climatic conditions of the Volgograd region. The location of agricultural land plots within the boundaries of the forest fund lands contradicts the land legislation, violates the safety and integrity of forest stands, leads to degradation, desertification and destruction of the ecological framework.
Assessment of the protective potential of the Moscow region soil cover to contamination with heavy metals and metalloids

Heavy metals and other trace elements that are not subject to degradation are among the priority pollutants. Significant amounts of heavy metals and related elements with variable valence are deposited on the soil surface as part of aerosols. Accumulating in the soil, they are very slowly removed from it, only changing the level of content or the state during migration, turning the soil over time into a source of secondary pollution. In this regard, an extremely urgent task is to assess the territory, especially such a highly developed and densely populated area as the Moscow Region, in terms of its protective potential to heavy metal pollution.

The paper proposes and tested an algorithm for the cartographic assessment of the protective potential of the soil and vegetation cover of the region using GIS analysis methods based on the database “Digital medium-scale soil map of the Moscow region” and a vector map of forest cover. The formula used for calculations includes data on the soil texture, the content of organic matter in soil, the position of the soil in the landscape and the degree of forest cover of the territory.

According to the proposed approach, in the Moscow region, the soil cover, taking into account the forest cover, forms 4 groups according to the level of protective potential for contamination with heavy metals and metalloids. The maximum estimate was obtained for noneroded sod-podzolic soils of medium or fine texture, gray forest soils, chernozems and peat bog soils under forest vegetation (17 % of the area). Unerroded soddy-podzolic soils of varying degrees of podzolization and gleying (45 %) received an average rating. Even lower is the protective potential of 22 % of the territory represented by eroded gray forest soils, various sod-podzolic, alluvial and peat bog soils. This group is the most heterogeneous in terms of soil texture, organic matter content and degree of forest cover. The group with a minimum protective potential included eroded soils, soils of gully-girder complexes, sod-podzolic soils of coarst texture, as well as alluvial peat and peaty soils (about 16 %).

Introduction. Most developing countries are still struggling for the efficient use of their resources. To overcome the physical and administrative development restrictions, it is necessary to transfer the powers of the central government to local authorities. The distribution of power from improves the management of resources and community participation, which is considered key to sustainable development. For Ukraine, the development of territories is one of the key issues of public administration, especially in conditions of decentralization. This is especially true of rural areas in view of the need to solve their socio-economic problems. Proponents of decentralization argue that the decentralized government is a source of improvement of community participation in the development of rural areas.
Goal – to study the state of development of rural areas in Ukraine, the EU, to identify peculiarities and generalize the directions of diversification in order to increase the efficiency of not only agricultural production, but also the social profile of rural territory.
Method (methodology). The research methodology is formed on the basis of evaluation of statistical data of the State Statistics Service of Ukraine (2017-2019) regarding the state of development of rural areas in Ukraine. Within the study, problems are identified as low efficiency of state support, and decline in rural areas. In the process of scientific search applied comparative, structural research methods.
The results. It is noted that the main attention in public administration should be given to rural territories. It is determined that their development depends precisely from the effective functioning of agrarian enterprises, in particular the farms of the population, in particular farmers, that is, areas of agrarian management as a whole. An analysis of the state of development of rural areas is carried out. Particular attention is paid to the features of rural territories, the normative settlement of decentralization in Ukraine and the main tasks of diversification, which are expedient to implement. It was revealed that Ukraine, seeking to be part of the EU should provide balanced development, in particular rural areas. Supernational support within the EU's efficiency of agriculture is analyzed. Despite the issues with the implementation, it is concluded that decentralization will change the existing policy of rural development in Ukraine as a result of changing the role of united territorial communities and the formation of such a development strategy, which will combine decentralization and economical and social development.
