The reproduction of forests is long-term. A complex and multifaceted silvicultural and technological process taking place in the conditions of disordered economic human activity and global warming. Reproduction of oak forests in the Central Black Earth Region, which are the cradle of Russian ship oak forests, has a regional specificity, which consists in the fact that in most forestries it is carried out mainly through artificial reforestation and sometimes combined. The reason is the complete absence of natural seed regeneration of oak under the canopy of mature and over-mature stands entering clear and selective sanitary felling.Even in narrow-cut and clear- cut areas, including those cultivated in accordance with the current requirements of the “Regulations for reforestation”, there is an intensive change of the main forest-forming species (pedunculate oak, common ash and Norway maple) to accompanying and less valuable (aspen, willow, birch , linden, hazel, etc.).On the basis of generalization of the long-term experience of the forestries of the region, logistics and silvicultural principles of sustainable-expanded, program- targeted and effective reproduction of oak forests are proposed and scientifically substantiated, without strict adherence to which, in practice, it is impossible to grow new durable high-quality, sustainable and highly productive oak forests with given target taxation characteristics. A step-by- step algorithm of sustainably expanded reproduction of oak forests of the future is considered. Prospects, ways and methods of high-quality and sustainably expanded reproduction of oak forests in the forestries of the Central Chernozem region have been determined.The prospects, ways and methods of high-quality and sustainably expanded reproduction of oak forests in the forestries of the Central Chernozem region have been determined. Controlled natural seed and artificial methods with the obligatory timely and high-quality agrotechnical and silvicultural maintenance, preventing the drowning of the pedunculate oak by other, faster-growing species, should become priority.

The aim of the study is to find out the feasibility of including green manured fallow in specialized sugar beet crop rotations by comparing necessary assessment indicators with their values in a traditional crop rotation with black fallow against the background of unequal fertilization levels. The study was based on the analysis of experimental data from a long-term stationary experiment, laid out simultaneously in all fields and variants on typical chernozem in triplicate. The results are as follows: within the same fertilization levels, no significant differences in the yield of winter wheat (sugar beet precursor) were revealed, and the yield of sugar beet in a crop rotation with green manured fallow was stably higher (no more than 5 to 7%), an increase in yield relative to the control fertilizer variant (6 tons of manure per hectare per year) against the background of a double rate of manure in combination with mineral fertilizers amounted to 21.7 to 23.4% for wheat and 14.3 to 15.6% for beets with an increase in the productivity of crop rotations (in natural and value terms) by 1.2 times, but an increase in costs by 1.3 times caused an absolute decrease in the level of profitability by 23 to 25%. Differences in the assessment indicators for specific fertilization variants increased over time due to an unequal degree of soil fertility reproduction, and therefore in the fifth cycle of the crop rotation with black fallow turned out to be 1.1 to 1.3 times greater than in the green manured rotation.

Agrarian Structure

The growth of modern systemic challenges in the context of globalization and integration processes leads to the creation of an effective regional agrarian structure, as one of the most pressing problems of scientific research in economic and social forecasting. The formation of an effective modern agrarian structure and the prospects for its long-term development will largely be determined by state policy, the institution of selective structural support for the state. The agrarian policy of the state to improve the institutional agrarian structure in the region on the basis of foreign and domestic experience should: - contribute to the growth in the number of family peasant farms in all sub-sectors of agriculture in all territories of the region; - create favorable economic conditions that stimulate the economy to create consumer (service) cooperatives of various specializations; - to economically stimulate large agro-industrial formations to interact with small forms of agribusiness. The conceptual directions and mechanisms of the long-term development of the agrarian structure in the Central Chernozem Region are defined, which include goals, stages, principles and objectives of the long-term development of the agrarian structure in the region, legal regulation, financial support, innovative development, the development of markets for agricultural products measures to implement the concept.

Under conditions of the Central Chernozem Region in the period from 1990 till 2012 long-term and short-term experiments were carried out in order to study the effect of different systems and methods of main soil treatment on weed infestation of plantings and yield of field crops. Soil and plant samples analyses were performed by customary methods. It has been defined that improved fall-ploughing and supplementary fall-ploughing at a depth of 6-8 cm allow reducing the quantity of weed vegetation in sugar beet plantings by 22 % and 33.3 % respectively compared to conventional (two-phase) fall-ploughing.

In 2020, the 75th anniversary of Victory in the Great Patriotic War was celebrated. Many soldiers and did not survive to see the end of the war. It is important that people living now remember and honor those who gave their lives for the freedom and independence of our country and those who came from the war in difficult conditions to restore the national economy of the country. In memory of those who courageously defended the independence of our great country, we named a new apple cultivar ‘Den Pobedy’ (Victory Day), which took 33 years to create. In 2020, this cultivar was included in the State Register of breeding achievements and it is recommended for cultivation in the Central-Chernozem region including Belgorod, Voronezh, Kursk, Lipetzk, Orel and Tambov regions. This cultivar was developed by crossing are quite commonly known winter cultivar ‘Veteran’ and foreign cultivar ‘Horcout’. Trees have a drooping crown. The main branches are curves. A characteristic feature of this cultivar is that the branches from the trunk depart at an angle close to straight. The main number of fruits is located on short fruit formations. Fruits are of medium weight (140 g), conical, wide-ribbed. The main color of the fruit at the time of harvest is greenish. The cover color occupies most of the surface of the fruit in the form of red blush. The fruit flesh is white, greenish of average density. The appearance (attractiveness) of the fruit is estimated at 4.4 points, and the taste - at 4.3 points (5-point rating). Fruits contain 14.7 % of sugars and 9.2 mg/100 g of ascorbic acid (vitamin C). Harvest in Orel region is in mid-September, the consumer period of fruits is until mid-March. The cultivar regularly bears fruit and has high product and consumer qualities.

ABSTRACT Within the context of the work and achievements of James Croll, this paper reviews the records of direct observations of glacial landforms and sediments made by Charles Lyell, Archibald and James Geikie and James Croll himself, in order to evaluate their contributions to the sciences of glacial geology and Quaternary environmental change. The paper outlines the social and physical environment of Croll's youth and contrasts this with the status and experiences of Lyell and the Geikies. It also outlines the character and role of the ‘Glasgow School’ of geologists, who stimulated Croll's interest into the causes of climate change and directed his focus to the glacial and ‘interglacial’ deposits of central Scotland. Contributions are outlined in chronological order, drawing attention to: (i) Lyell's high-quality observations and interpretations of glacial features in Glen Clova and Strathmore and his subsequent rejection of the glacial theory in favour of processes attributed to floating icebergs; (ii) the significant impact of Archibald Geikie's 1863 paper on the ‘glacial drift of Scotland’, which firmly established the land-ice theory; (iii) the fact that, despite James Croll's inherent dislike of geology and fieldwork, he provided high-quality descriptions and interpretations of the landforms and sediments of central Scotland in order to test his theory of climate change; and (iv) the great communication skills of James Geikie, enhanced by contacts and evidence from around the world. It is concluded that whilst direct observations of glacial landforms and sediments were critical to the long-term development of the study of glaciation, the acceptance of this theory was dependent also upon the skills, personality and status of the Geikies and Croll, who developed and promoted the concepts. Sadly, the subsequent rejection of the land-ice concept by Lyell resulted in the same factors challenging the acceptance of the glacial theory.
