The vertical structure of clover-cereal and cereal meadow grasses depending on their composition, mowing period and growing conditions in the Novgorod region of the North-West of Russia
Authors: Bevz S Y , Burova S S 
Published: December 2020

Abstract
Data are presented on the study of the influence of the composition of meadow cenoses, the term of their mowing, and the dose of mineral nitrogen on the distribution of phytomass along the height of clover-grass and grass meadow grass stands. It has been experimentally proved that the composition of agrocenoses, their mowing time and growing conditions have a great influence on the vertical distribution of the vegetative mass of meadow grass stands. For mowing use on medium-acid soils of heavy mechanical composition, legume-cereal grass with hybrid clover included in its composition is most suitable. On average over the years of research, this meadow agrocenosis cropped from the full budding phase to the full bloom phase is characterized by the most uniform phytomass distribution over the height of the grass stand. In addition, it was experimentally confirmed that the introduction of mineral nitrogen fertilizing under cereal meadow grass stands contributes to a more even distribution of vegetative mass along the agrocenoses height. When nitrogen is applied in a dose of 120 kg per 1 ha under cereal grass stand, there is a significant shift of the “center of equilibrium” up the height of the grass stand and a reduction in the amount of phytomass in the lower tier compared to unfertilized cereal agrocenosis, which is important when mowing grass meadows.

Abstract
The purpose of the study was to explore food diaries to identify differences in the received nutrients between students living in a relatively ecologically safe area and polluted region. The sample included 179 participants living in Stavropol (ecologically safe area) and Nevinnomyssk (polluted region) at the age of 17 to 23 years. Dietary intake was estimated using a 7-days food diary and nutrient intake adequacy using the computer program “Nutrition for health and longevity”. Participants did not significantly differ in age, gender, height and weight. There were total caloric and nutrients shortage in most of all students, regardless of the residence. Reduced fat consumption and pronounced deficiency of biotin, beta-carotene, choline, vitamins A, C, B6, B12, D, I, manganese, Fe, S, F, Se and Zn was found. Severity of protein, niacin, K, Ca, Mg and P deficiency in diet was higher in polluted area compared to the relatively ecologically safe area. In this regard, there are several related issues that need to be addressed in the future. These are the intake of heavy metals from food, the production and use of environmentally friendly food, and the development of functional products for students and residents of polluted regions.

Abstract
The presence of coarse fiber in newborn animals indicates the viability and high productivity of animals in adulthood, therefore, when breeding meat-wool sheep of the Jalghin merino breed, flocks of lambs should be formed according to the amount of coarse fiber at birth. It was found that in all groups, animals born with coarse fiber at all age periods had superiority in live weight over animals born without coarse fiber. In group I of the fine line, 72.5% were born without coarse fiber, and 27.5% with coarse fiber. In group III of the strong line, 13.6% were born without coarse fiber of lambs, 86.4% with coarse fiber. In the second group of the medium line, there was practically the same ratio of without and with coarse fiber lambs and amounted to 48.7% and 51.3%, respectively. It was found that, at birth and at 4 months of age, in terms of live weight, rams with coarse fiber, regardless of their linearity, outnumbered their peers. At 14 months of age, the superiority of animals of group III in live weight in general over their peers in groups I and II was 8.8% (P <0.001) and 5.4% (P <0.001). In turn, the rams of the III group that were born with coarse fiber had a significant superiority over the coarse-fibered peers of the I and II groups by 5.6% (P <0.001) and 2.8% (P <0.001). The same tendency was noted for the rams that were born without coarse fiber, animals of the III group (strong) had a significant superiority over their peers (fine and medium).

Authors: Dmitruk N G , Druzhnova M P 
Published: December 2020

Abstract
The article considers the issues of establishing correspondence between soil-forming factors and soil properties. The aim is to determine the degree of natural soil fertility in the context of its agricultural use in the Novgorod region. The main soil-forming factors are the Quaternary mother rocks and modern sediments, in some areas they are represented by the Paleozoic indigenous deposits. Soil formation largely depends on climatic features, hypsometry, rugged terrain and vegetation, which are heterogeneous within the Novgorod region. These factors undermine the processes of podzol, peat and gley formation and sod process, which jointly determine the mosaic of the soil cover. The authors have examined the soil-geographical areas of the Novgorod region, given the characteristics of soils and identified measures connected with agricultural activities and special techniques aimed at improving the soil properties and increasing fertility.
Analysis of foreign and domestic practice of operating sludge platforms to minimize negative environmental impact
Authors: Dregulo A M , Vitkovskaya R F 
Published: December 2020

Abstract
For many European countries, including the United States and Russia, the use of sludge platforms is one of the most appropriate methods for treating sewage sludge. However, a comparative analysis of the operation of sludge platforms showed that the practice of treating sewage sludge on sludge maps in Russia is of little use. Technological methods used to optimize their processing processes require significant revision. Foreign practices are most adapted both to the removal of excess moisture from the sludge and to the neutralization (treatment) of sewage sludge from heavy metals and other soluble forms of pollutants.

Published: December 2020

Abstract
Veliky Novgorod has considerable potential for birdwatching development due to its rich bird biodiversity and possibility of combining cultural and eco-tourism, as more and more people are interested in the quality of the urban environment. Reporting of bird sightings by members of the public provides an opportunity to collect data continuously over wider geographical areas, increase detectability of species. Modern technologies greatly facilitate what was previously available only to professionals: photo and video recording of sightings, definition of species. This potential is not fully realized, which is clearly demonstrated by the fact that the all-Russian platform Online Diaries of Bird Observation does not provide data for the Novgorod region at all. The research methods were: observation, survey of students, teachers, and employees of the Institute of Agriculture and Natural Resources, analysis of cartographic data for 2016-2020. The community of amateurs is concentrated around enthusiasts of professional ornithologists, as in the community of Birds of Novgorod Region. Since 2016, Veliky Novgorod has been providing data on the Nightingale evenings platform, after an increase in 2017, the number of respondents remained the same. Since only a part of respondents are permanent, and there are no regular routes for shift ones, the coverage of districts is uneven. Each year information is provided by 16-28 people, sightings vary from 84 to 116. To attract birdwatching volunteers to monitor birds in Novgorod region, one needs to develop a special project, including through NovSU project activities.

Authors: Korovkina A , Zhirov V , Tsvetov N , Petrashova D 
Published: December 2020

AbstractFlavonoids represent a wide group of polyphenols involved in many key processes of plant growth and its can be successfully used in medical practice. In plants that are exposed to extreme factors of various nature, the flavonoids synthesis occurs more intensively compared with plants of the same species growing under more favorable conditions. Thus, it can be assumed that it is the Arctic plants that can be important sources of flavonoids. This paper presents the results of a search for flavonoid sources among herbaceous plants growing in the Arctic zone, in particular, the Murmansk region. The total flavonoid content in ethanol extracts of 24 plant species was estimated using the reaction of complexation with aluminum chloride. It was shown that Lathyrus pratensis L., Lupinus arcticus L., Hedysarum alpinum L., Chamaenerion angustifolium L., and Polygonum weyrichii species contain the highest amounts of flavonoids.

Published: December 2020

Abstract
The article presents materials on the use of selenium compounds in the production of biological fertilizers, the main active component of which being artificially cultivated nodule bacteria. The objects of research in this work were various types of bacterial organisms used to prepare bacterial fertilizers: symbiotic nitrogen-fixing bacteria (rhizoagrin, rhizotorfin for galega and pea) and free-living agrobacteria (agrophil). Sodium selenate (Na2SeO4) was used as a source of selenium. The most optimal concentration of selenium ions in the liquid culture of microorganisms was 10–4 g/kg. A positive effect of selenium on the titer of finished preparations was observed: on average for the study period Rhizobiumpisum (rhizotorfin for peas) and Agrobacter 10 (agrophil) on the variant with selenium exceeded that on the control variant by 35.2 and 26.6%, respectively. The absolute titer values of the finished preparations Rhizobiumpisum (pea rhizotorfin) and Agrobacter 10 (agrophil) on non-sterile peat turned out to be higher than on sterile peat, although the trend remained. The inoculation of pea seeds with bacterial preparations increased the number of nodules in the flowering phase on the roots of pea plants by 1.8–2.1 times compared with the control. The treatment of pea seeds with rhizotorfin activated by selenium compounds during its manufacture increased the grain yield by 0.51 t/ha (17.1%) compared with the control, and by 0.30 t/ha (10.0%) when inoculated with rhizotorfin.

Published: December 2020

Abstract
A combination of properties of osteoplastic biocomposite materials, including biological compatibility and biodegradability, puts them in the category of high-tech materials of the 21st century. Biomedical technologies related to the development of materials and devices for reconstructive surgery are particularly promising areas of application of osteoplastic materials. Despite the apparent progress of reconstructive oral surgery, the closure of postoperational extensive alveolar bone defects remains a pressing medical and social problem, for example, plasmocytoma. This disease implies not only treatment by hematologist-oncologist, but also surgical removal of osseous defect followed by its closure, which is a difficult prognostic and time-consuming process. No data on the long-term results of monitoring such patients are available in the literature.

Authors: Lapteva N G 
Published: December 2020

Abstract
At the present time, the search for natural ingredients that improve characteristics of minced meat products, and reduce the amount of synthetic food additives is going on. Plant components are the most popular. Most often they are recommended to be added in the powder form. This helps to improve technological properties of minced systems, as well as reduce the cost of products. In the article the possibility of applying prunes in the composition of minced beef is considered. The effects of prunes on an increase in water-holding capacity of minced meat to 54.4 % in a sample with 20% prune content, a decrease in water loss during 10 days of storage in a frozen state by 4.4 % in the same sample, an increase in the yield of finished products during thermal processing by 8.9 % are shown. It was found out that the color of finished products is within the acceptable range when decreasing the proportion of sodium nitrite to 0.003 % in the recipe, and even at its absence.
On the issue of enrichment of bakery products with functional components
Authors: Lapteva N G 
Published: December 2020

Abstract
The enrichment of food products with natural protein components of plant and animal origin is an important task of the food industry. The problem of lack of protein in the diet is observed among different segments of the population. This is due to the wrong choice of products, commitment to fast food restaurants, metabolic disorders. Bakery products are in high demand. They provide the basis for the energy component of the daily diet due to the high content of carbohydrates. In addition, bread contains B vitamins, essential minerals and fiber. Nutritionists advise giving preference to whole grains and rye bread. However, the popularity of short products remains at a high level. Enrichment of wheat bread with biologically valuable components will increase the level of consumption of nutrients important for humans. The article presents the results of studies of the quality of bakery products when making up to 8% protein peanut mass in the recipe. A technology is proposed for preparing peanut beans before being added to the dough, as well as a sponge method for producing fancy bread. Organoleptic characteristics, acidity and porosity of the crumb were evaluated in the product, the mass fraction of protein was determined, which amounted to at least 12.5% in the experimental samples. The research results prove an increase in the protein content in finished products, as well as the beneficial effect of the additive on the sensory and technological properties of the product. The addition of peanut mass to the composition of bakery products led to an increase in the energy value of the product, which amounted to 325 kcal in the experimental samples.

Published: December 2020

Abstract
The situation with dyspepsia of young animals in the postnatal period in agroindustrial companies of Russia remains tense due to a high mortality rate. Specialists are not always able to cover a wide range of drugs currently available on the market, although the success in combating the disease depends on a timely introduction of highly effective drugs and various combinations of treatment regimens into practice. The paper presents the findings of studies on the use of various treatment regimens for dyspepsia of newborn calves, with the inclusion of an immunomodulator. The studies have shown high therapeutic efficacy of both antibacterial drugs Cobactan and Neopen, and their use in combination with the drug Phosprenyl. Laboratory studies of morphological and biochemical parameters of blood demonstrated significantly improved concentration and percentage of the drugs. In the course of treatment with basic drugs, the immunomodulator Phosprenyl enhanced their action and positively affected the percentage composition of the leukoformula. Daily clinical examination of young experimental animals showed that treatment with Cobactan, especially in combination with Phosprenyl, is most effective in terms of fastening recovery and safety of calves.
Cadastral value of land taking into account geo-environmental factors

Published: December 2020

Abstract
An urgent task is to determine the cadastral value of land, taking into account the geo-environmental factors affecting the production of environmentally friendly agricultural products and the health of citizens living in the respective territories. The contamination of the territory of the Novgorod region caused by natural and technogenic factors is considered. Natural factors include earth’s crust fractures and the associated infection of the territory with radon. Technogenic factors include the consequences of the accident at the Chernobyl nuclear power plant. Basic concepts from the field of measuring radiation contamination of a territory and human radiation doses are given. Radioecological disturbances are considered: earth’s crust fractures, territories with exceeded norms for the content of radon, cesium, potassium, thorium and uranium. Thematic mapping of radioecological violations was done in the environment of the Mapinfo program. Herewith, a schematic ecological map in raster format and a vector map of the region were used, on the basis of which thematic maps were created. On the basis of building norms and rules, as well as using the cost method of decontamination to reduce the radiation dose per 1 person-sievert, it was proved that the cadastral value of agricultural land should be reduced by fifty percent relative to its current values. The dependence of oncological morbidity in the region on the radiation infection of the territory is shown cartographically. Infection with cesium does not significantly affect the irradiation dose. It is necessary to monitor the state of radioactive potassium, and one-time measures should be taken to decontaminate the territory from thorium and uranium. The cost method justifies the cost of such measures per hectare of land.
