Commercial horticulture in many regions of the world depends upon Sphagnum peat as a potting-media substrate, but extracting peat has serious environmental consequences. Composts may be able to serve as effective substitutes for peat and offer potential environmental advantages. The suitability of compost as potting media depends upon the raw materials as well as processing methods used. This study includes two related experiments—one with beet (Beta vulgaris L.) and the other with tomato (Solanum lycopersicum L.)—aimed at assessing the potential viability of farm-produced, food-residuals compost as a replacement for peat-based potting media in the production of organic vegetable transplants. The experiments were conducted in 2021 on the Berea College Farm in Kentucky, USA, a USDA certified organic farm. The results indicated that potting media composed of 75% to 100% compost performed as well as fertilized, peat-based growing media for plant growth. Further, although weeds were present in the compost, weed pressure was not severe enough to adversely affect crop growth. Thus, sterilization of compost, which did eliminate weeds in the compost, was not deemed necessary for using the compost as a partial or complete potting medium. Compost pasteurization was also assessed but was ineffective in destroying weed seeds.

The author of the article discloses the prospects of development of the world feed production for aquaculture based on the analysis of key innovative technological and market trends. The author specifies that shortage, high cost, low ecological compatibility of traditional raw materials - fish flour - are among major limiting factors in the development of production of feeds for aquaculture. This fact, in turn, limits sustainable development of aquaculture both in Russia, and in the world in general. The article presents the overview of a current status of the world industry of feed production in aquaculture, where the regional situation is studied, as well. For the first time, there is given the outlook of innovative technologies in feed production based on the alternative sources of protein (on the example of projects of leading aquabiotechnological companies) which will determine industry’s objectives for the mid-term perspective.

Проанализированы проблемы на рынке молока и молочных продуктов России в условиях глобального экономического кризиса: перепроизводство молока в основных странах-экспортерах, снижение закупочных цен на сырое молоко, снижение цен на биржевые товары в мире и России в 2020 году, тренд на уменьшение спроса на молочные продукты на мировом рынке в среднесрочном периоде, снижение общего спроса на молочные продукты на внутрироссийском рынке при падении реальных доходов населения, изменение структуры потребления. Проведена оценка новых возможностей и угроз для развития отрасли: со стороны потребителей — рост цен на продовольствие, снижение доходов; с позиции производителей молока — снижение закупочных цен, рост требований к сырью для производства продукции с увеличенными сроками годности, дефицит рабочей силы, вероятное сокращение господдержки в результате снижения цен на углеводороды, попытки регулирования цен; со стороны перерабатывающих предприятий — сокращение спроса, снижение цен на готовую продукцию вслед за мировыми ценами. Обоснованы приоритеты инвестирования в молочном скотоводстве и основные формы совершенствования государственной поддержки отрасли, обеспечивающие эффективную адаптацию производителей молока к новым экономическим условиям, повышение устойчивости отрасли при усилении макроэкономических рисков. The article analyzes the problems in the Russian milk and dairy products market in the context of the global economic crisis: overproduction of milk in the main exporting countries, lower purchase prices for raw milk, lower prices for commodities in the world and in Russia in 2020, trend to reduce demand for dairy products on the world market in medium term, a decrease in total demand for dairy products in the Russian market with a decrease in the purchasing power of the population, a change in the structure of consumption. An assessment of new opportunities and threats to the development of the industry was carried out: on the part of consumers — rising food prices, lower incomes; from the perspective of dairy producers — reduction in purchase prices, increased requirements for raw materials for the production of products with extended periods, labor shortages, the likely reduction in state support as a result of lower prices for hydrocarbons, attempts to regulate prices; on the part of processing enterprises — reduction of demand, reduction of prices for finished goods following world prices. The investment priorities in dairy cattle breeding and the main forms of improving state support for the industry, ensuring the effective adaptation of milk producers to new economic conditions, increasing the sustainability of the industry with increasing macroeconomic risks, are substantiated.

AbstractThis paper analyses the commodity price pass-through along the pricing chain for the global commodity price index and the indices of its main categories (i.e., agricultural raw materials, food and beverages, energy and metals) in the world, advanced and emerging economies. To do so, the study considers country-by-country vector autoregression models and pool the results by taking weighted means for 18 advanced economies and 19 emerging countries, as well as for the world (defined as the sum of advanced and emerging economies). The results show the following: (i) there is evidence in favour of partial pass-through from commodity prices to producer prices, although the evidence for the pass-through to consumer prices is less evident; (ii) the pass-through in the world seems to be led by both advanced and emerging countries for producer prices and only by advanced economies for consumer prices; (iii) higher prices in the four categories (agricultural raw materials only in the short-run) induce significant higher producer prices in almost all cases, with shocks in the prices of energy and metals showing the largest effects; and (iv) energy prices explain the highest variability of producer and consumer prices.

Plant is not only closely related to human beings’ life, but also an integral part of raw materials in production. Protection of nature and plant resources is an increasingly urgent needs around the world. Cognition is a prerequisite for the protection of plant. But the way of plant science popularization is old, the knowledge of plant is too obscure to the general public. The system of plant science popularization based on the QR code spreads the knowledge of plant with illustrations interactively, to facilitate ordinary users to learn, understand and identify plant species. The article will detail all aspects of development of the system, allowing more scholars to understand the digitized plant science popularization under the new media.

The place in the rankings of agricultural exporting countries in world trade is estimated in terms of the volume of imports and exports of raw materials and food. However, to assess the efficiency of agricultural exports, it is important to analyze the value added of exported goods produced in the country. The position of the exporting country in global value chains is derived from the type of agricultural production, which in turn depends on the level of development of the national economy, the availability and breadth of use of modern high technologies. The article examines the concept of the development of world agriculture from the point of view of the formation of global value chains, set out in the report of the UN World Food Organization [1] in comparison with the political decisions of such countries as India and the People’s Republic of China in the development of agricultural and food exports. The paper analyzes the risks associated with the consolidation of developing countries as suppliers of agricultural raw materials, as well as the conditions and action plan that allow the country-exporter of agricultural raw materials to move to higher levels in the global value chains on the world market. This experience should be considered to make comprehensive and effective decisions on the formation of the export policy of agricultural products and food of the Russian Federation, considering the food security of the country.

Exporters of raw materials under Iberian rule, the nations of Latin America continued to perform a similar role in the world economy after Independence. In the nineteenth century, however, a significant shift occurred in the kind of materials exported. Whereas in colonial times the great wealth of Latin America lay in her mineral resources, particularly silver and gold, aster 1850 agricultural production for foreign markets took on larger importance. The export of foodstuffs was not a new phenomenon, but in the nineteenth century the growth in consumer demand in the industrializing nations and the developing revolution in. transport much enhanced the incentives for Latin Americans who would produce coffee, wheat, cattle, or bananas for overseas markets.

If by the term ‘matter’ is meant the extended, movable, and corporeal stuff out of which perceptible objects are made, then, according to one interpretative tradition, there is nothing in Aristotle's account of the world that corresponds to matter in the above sense of physical stuff. Aristotle does indeed describe certain things as extended, movable, and corporeal: for example, the five elements, earth, water, air, fire, and ether, as well as everything made out of them. He also has the concept of a material cause, that is, the raw materials out of which something can be made or generated, and he makes frequent use of this concept in his analysis of perceptible substances. Still, the fact that Aristotle thought about what perceptible substances are made of is insufficient evidence for attributing to him the concept of matter as physical stuff. In addition, we would want to know whether he thought that all perceptible substances are extended, movable, and corporeal precisely because they are made out of matter, and whether any aspect of their behavior is to be explained simply by virtue of their nature as material objects.

Complex and contradictory processes of modern social transformations and the need to overcome the crisis in the economy require the appropriate influence of the state and a clear system of socio-economic management through the formation and implementation of effective state economic policy. The main elements of economic policy are financial and credit, budgetary, scientific and technical, structural, social, investment, agricultural, regional, foreign economic policy. The implementation of state economic policy is considered in terms of the relationship between social problems and the state. Therefore, the purpose of the article is to study the essence, tools and methods of state economic policy in modern conditions. It is also necessary to identify the main risks and features of further development of state economic policy of individual states in a global imbalance and crisis. The theoretical part is devoted to the study of the essence of state economic policy, theoretical and practical aspects of its organization in the state, as well as tools that can be used by the state. The resulting part is devoted to the consideration of the situation, in which the world economy has found itself in 2020 in the conditions of the economic COVID-19 crisis. General forecasts have not provided to individual states because it has been impossible to predict the end of the pandemic and the return of the world to normal life. However, it is clear that the world economy has undergone irreversible processes that will synergistically affect different states in different ways. The crisis has hit a significant number of industries, including tourism, logistics, hotel business, the crisis has been felt in world markets: oil prices have collapsed, as well as the stock markets. Undoubtedly, there are areas with a rapid growth, especially the pharmaceutical industry and retail, online delivery services, IT entertainment and communications industry, information marketing business and education and training services. It is likely that the indicators of economic development in the states by the end of the year will be better than the results of the first half of the year. The basic forecast of economic world development assumes a sharp growth of the economy after a short recession after quarantine. The financial capabilities of the EU states vary considerably, but each state must pursue counter-cyclical policies aimed at stabilizing its own economy. The answer to the question of what kind of crisis response policy they can afford depends on the fiscal policy of the states before the crisis. In economically developed states, where emergency measures have been introduced, governments and central banks issue trillions of dollars in government spending, social support of citizens, and interest-free business loans to limit the economic damage of quarantine. At the same time, in Latin America and Southeast Asia, total quarantine is impossible in multi-million cities. Such states have a triple effect of suffering from the virus, the environment and poverty. States dependent on the export of natural resources and raw materials, when faced with the crisis, are forced to sell them for nothing, so they will suffer great losses. More than 150 states have set up anti-crisis headquarters and are taking anti-crisis measures. The authors have also tried to predict how largescale the global economic crisis will be for Ukraine, what consequences await it, and what measures need to be taken to overcome it.
