The Impact of Agricultural Use of Retisols on the Molecular Structure of Humic Substances

Agricultural soil use does not only affect the amount of soil organic matter, but also the molecular composition of humic (HAs) and fulvic acids (FAs). Changed hydrothermal conditions and composition of the incoming plant residues are reflected in the rate of humification and its products. The objective of this study was to compare the molecular composition of HAs and FAs isolated from Eutric Albic Stagnic Histic Retisol (Loamic), two Eutric Albic Retisols (Loamic)—mature and arable. Plots of mature Retisols are located at a middle taiga (Komi Republic, Russia) in a bilberry-green-moss birch-spruce forest. The plot of Retisols arable is located in the fields of the Syktyvkar state farm, which is 3.3 km northeast of mature Retisol plots. The development period is about 40 years, it is sowed with a pea-oat mixture. The results obtained indicate that soil reclamation essentially increases the proportion of aromatic components and decreases the content of carboxyl and ester groups in the humic substance (HS) structure. An increased extent of hydromorphism of Retisols leads to the enrichment of HS with aliphatic fragments.

Determinants of Preferences of the Respondents for the Payment for Environmental Services among the Rural Farming Households in Oyo State Nigeria

This study attempted to uncover the factors that influence preferences of the poor farming households for the attributes of Payment for environmental services (PES) in the Oyo State farm settlement Nigeria. Educational attainment, age of the respondents, previous knowledge of PES, land tenure, provision of micro credit, number of dependents, marital status and main occupation of the respondents. Dependent variable is preference for PES attributes.A multi-stage sampling technique was employed for this study.This study used exclusively Primary data.Which were collected through the use of a well-structured questionnaires and interview schedule for the literate and non-literate farmers respectivelyTotal sample of 395 out of 547respondents (i.e.72%) were drawn cumulatively. The regression results showed that previous knowledge of PES and provision of microcredit are significant at 5% each, while land ownership right is significant at 10% in the educational poverty group. In the consumption poverty group, previous knowledge of PES is significant at 5%, while land ownership right is positively significant at 1%, respectively. Housing/living standard poverty group; previous knowledge of PES and land ownership rights are significant at 5% each. From the findings of this study, it implies that if micro credit facilities are provided to these poor farming households, they will be willing to conserve the environmental resources (i.e. agricultural land). It therefore suggests that a well thought institutional arrangement with PES in view could be put up to enhance natural resource conservation and by extension reduction of poverty.

THE INFLUENCE OF MIGRATION PROCESSES ON THE FORMATION OF THE URBAN OBJECT STRUCTURE

In the article was found that the planned location of new or expansion of existing production clearly coincided with the movement of certain segments of the population to these regions for employment, examining and analyzing the problems of migration of the population of the former USSR. The researches of the Russian town-planners Bocharov Y.P., Belousov V.M., Vladimirov V.V., Maloyan G.A., Lezhava I.G. and other are devoted the problems of development of the theory of settlement with loss of planning component in development of systems of settlement and general plans of cities in new market (social and economic) conditions. Leading domestic urban planners have devoted their research to the problems of the development of the theory of settlement in Ukraine, the system of settlement and the development of master plans in modern market conditions (1992-2014). Some of them are Filvarov G.K., Yezhov V.I., Demin M.M., Lavrik G.I., Repin V.M., Timokhin V.O., Shkodovsky Y.M., Rudnitsky A .М. and other. The article presents the stages of formation of production relations, social, economic, architectural and spatial evolution under the pressure of migration processes, based on the analysis and research: The formation of the labor market (places of employment) in the development of industry, transport links and resettlement (early nineteenth - early twentieth century). Urbanization of cities in the early twentieth century due to migrations (free labor) from near and far agglomerations. Urbanization of the late twentieth century due to the release of labor (the collapse of the collective and state farm system). Under the pressure of migration and transport processes the compositional and planning spatial structure of the city is determined by the following aspects: the hierarchy of the city in the general network of settlements; the level of the city's public transport network; mobility of city residents; location of attractive objects for migrants in the city planning structure; socio-demographic characteristics of residents. Territories of cities with developed production are becoming the poles of industrial industry with the latest technologies, as well as centers of business.

Collective Farm Village of Mordovia in the Post-War Period

Introduction. The article explores the state of the collective farm village of Mordovia in the post-war period, when the peasantry went through a difficult and contradictory path of development, having experienced all the consequences of state policy, which was characterized mainly by the use of repressive measures and increased taxes. At the same time, the moral encouragement of the leaders of collective farm production was used, the material and technical base of collective farms was gradually strengthened. Results and Discussion. Yield growth, livestock and productivity of public animal husbandry, the strengthening of the economy of farms largely depended on the efficiency of the work of collective farmers, state farm workers, advanced production workers, agricultural production specialists. The improvement of the material well-being and cultural level of the workers of the region, first of all, was expressed in the growth of the monetary income of collective farmers, workers and employees, in housing construction. The reduction of the agricultural tax in 1953, the increase in procurement and purchase prices for agricultural products, the decrease in retail prices for some food and industrial goods, the transition to monthly and quarterly advance payment of labor changed not only the economic situation, but also the psychological climate in the village: the social and labor activity of people increased, the migration of the rural population of Mordovia decreased. Conclusion. The progressive measures implemented after September 1953 soon exhausted themselves due to systemic reasons and contradictory subjective decisions.

253 Physiological Responses to Heat Stress of Holstein Heifers Carrying the SLICK1 Allele of the Prolactin Receptor (PRLR) Gene

The objectives of this study were to evaluate physiological responses to heat stress of Holstein heifers carrying the SLICK1 allele of the PRLR, i.e., the slick mutation. Slick and non-slick females were produced in central CA (n = 3 farms) and south FL (n = 3 farms) by inseminating cows with semen from two heterozygous slick Holstein sires. In July 2020, a subgroup of heifers of both genotypes (slick=93; non-slick=110) and two age groups (Group 1: 6–8 months old; n = 131; Group 2: 9–51 days old; n = 72) in both states were evaluated for rectal temperature (RT), surface temperature (ST) and sweating rate (SR). Dry bulb temperature, relative humidity and dew point were recorded every 15 min during testing for temperature humidity index (THI) calculation. Statistical models included the effects of genotype, state, farm within state, group, sire, THI, and interactions. Significant effects were considered as those with P < 0.05. Although the THI in CA was lower than FL (80 ± 0.1 vs 84 ± 0.2; P < 0.01), both were above 77 (estimated heat stress threshold for young animals). Slick heifers raised in FL had lower RT compared to non-slick siblings (39.6 ± 0.1 vs 40.1 ±0.1; genotype P < 0.01); this difference was not observed in CA (39.1 ± 0.04 vs 39.1 ± 0.05; genotype P = 0.5; state x genotype P < 0.01). In both states, slick heifers tended to have lower ST (34.7 ± 0.2 vs 35.1 ± 0.2; P = 0.07); CA heifers had lower RT and ST and higher SR (P < 0.01) regardless of genotype. Current results show that presence of the SLICK1 allele can improve the ability of Holstein heifers to regulate body temperature, particularly in high humidity conditions. Next steps will include analysis of performance as study animals enter the reproductive phase. Funding sources: Holstein Association USA and L.E. “Red” Larson Endowment.

About Bang's disease in Dauria

In the summer of 1930, in the sheep-breeding state farm Krasny Giant, located in the southern steppe part of Eastern Transbaikalia, a massive disease appeared among the shepherds, which remained unrecognized. The number of cases also remained undetermined, apparently about 20. Two patients who were admitted to the Daursky military hospital died.

еvaluation of meadow clover varieties selection of smolensk goshos in the collection nursery

В статье представлены результаты оценки сортов клевера лугового селекции Смоленской ГОСХОС по урожайности зеленой и сухой массы и хозяйственно-ценным признакам за 2019-2020 годы. Целью наших исследований являлось изучение восьми перспективных сортов клевера лугового для рекомендации их возделывания в условиях Псковской области и возможного использования в селекционной работе. Исследовательская работа с сортами клевера лугового проводилась в коллекционном питомнике на опытном поле лаборатории агротехнологий ОП Псковский НИИСХ, который был заложен в 2019 году. Высокий урожай зеленой массы и сухого вещества, в сумме за два года пользования, показали сорта: Надежный – 19,2 т/га (от стандарта +4,4 т/га), Тайлен – 18,9 т/га (+ 4,1 т/га), Смоленский 29 – 18,1 т/га (+3,3 т/га), Починковец – 16,9 т/га (+2,1 т/га) и Делец – 15,1 т/га (+1,5 т/га). Погодные условия вегетационного сезона в 2019 и 2020 годах были благоприятными для роста и развития клевера лугового. Укосная спелось – фаза начала цветения клевера, у раннеспелых сортов наступила в среднем на 9-17 дней раньше, чем у позднеспелых. Засорённость травостоев в первом укосе второго года пользования составила 5-7% и повышалась во втором укосе по некоторым сортам до 30% видового участия. В первый год жизни растений наибольшая облиственность была у раннеспелых клеверов и составляла от 43 до 48%. Во второй год жизни – год основного использования травостоев клевера, от укоса к укосу облиственность растений клевера повышалась. Самый высокий показатель дружности отрастания был отмечен у сортов Починковец, Смоленский 29, Делец и Стодолищенский. Для возделывания в условиях производства в Псковской области можно рекомендовать сорта Надежный, Тайлен, Смоленский 29, Починковец и Делец. The article presents the results of the evaluation of meadow clover varieties selected by the Smolensk state farm according to the yield of green and dry mass and economically valuable characteristics for 2019-2020. The purpose of our research is to study eight promising varieties of meadow clover to recommend their culti- 25 vation in the conditions of the Pskov region and possible use in breeding work. Research work with varieties of meadow clover was carried out in a collection nursery on the experimental field of the laboratory of agricultural technologies of the Pskov research institute, which was founded in 2019. The high yield of green mass and dry matter, in total for two years of use, was shown by the Reliable varieties – 19.2 t/ha (from the standard +4.4 t/ha), Tailen-18.9 t/ha (+ 4.1 t/ha), Smolensky 29 – 18.1 t/ha (+3.3 t/ha) and Delets – 15.1 t/ha (+1.5 t / ha). The weather conditions of the growing season in 2019 and 2020 were favorable for the growth and development of meadow clover. The mowing season is the phase of the beginning of clover flowering, in early-maturing varieties it occurred on average 9-17 days earlier than in late-maturing varieties. The weed infestation in the first mowing of the second year of use was 5-7% and increased in the second mowing for some varieties up to 30% of the species participation. In the first year of plant life, the highest leafiness was in early-maturing clovers and ranged from 43 to 48%. In the second year of life – the year of the main use of clover herbage, the leafiness of clover plants increased from mowing to mowing. The highest rate of amity of reg rowth was noted in the varieties Pochinkovets, Smolensky 29, Delets and Stodolishchevsky. For cultivation in production conditions in the Pskov region, we can recommend the varieties Reliable, Tailen, Smolensky 29, Delets and Pochinkovets.

On the issue of alcoholic psychoses in children and alcoholism among young people

While on a business trip for agricultural health care. workers in the spring sowing campaign in 1931 (Kolpakovsky state farm Sakhkombpnata "Collectivist" Ivaninsky district Ts. Ch. O), I observed a case of acutely developed alcoholic psychosis in a peasant boy of 3 years of age.

Transformation of traditional reindeer herding technologies and pasturing practices 206on the Kola Peninsula in the 20th— early 21st century

The purpose of the article is to give an accent presentation of the transformation of technologies and tech-niques of reindeer grazing and value attitudes of the Kola reindeer herders in the 20th — early 21st century from an ethno-cultural perspective. The paper is based on the materials of the 2018 expedition to the Kola Peninsula. On the basis of using a system-analytical approach, the paper is structured as a narrative discourse, where the “floor” is given to the Kola reindeer herders themselves. As the studies show, the changes in the Kola reindeer husbandry brought about by the merger of the nomadic Samoyed-Izhem Culture, introduced to the Kola peninsula in the late 19th — early 20th century, with the semi-nomadic “cabin” Saami herding style, as well as by the Soviet period collective and state farm transformation of the traditional reindeer husbandry and the unfolding “snowmo-bile revolution” (the use of the reindeer sled has been reduced to one month in a year), have led not only to the loss of numerous traditional reindeer herding technologies, pasturing practices and herd control, but also to sig-nificant changes in the population composition, structure, and organization of the behavioral characteristics of the herds. Today, the Komi-Izhem reindeer husbandry is dominant in the Kola region. However, despite the major changes, the Kola herders are still quite flexible in using, depending on the circumstances, the advantages of both the Izhem and the Lapp reindeer husbandry systems. The return to the semi-free herds ranging practices and transition to rotational organization of reindeer herd tending in the post-Soviet period stimulated the economic revival of the herding industry and added more comfort to the reindeer herders' lifestyle, although the reindeer herding is not considered a prestigious occupation among young people. Rethinking the older generation's life experiences, together with the more critical perception of today's realities, is an indication of changes within the system of ethnic values, which formerly, in a sense, supported both the individual and collective identities of the Saami and Komi-Izhem ethnies. The transformation processes have had a particularly profound impact on the traditional Saami reindeer culture, almost destroying it, which causes painful memories and reactions of its last bearers. Displacement of the Lapp component is carried forward in the choice of preferred deer breeds and dis-appearance of the Saami language and Saami toponymy from the reindeer herding context.
