Article is devoted to studying the issues of foreign language education and the main approaches to realizing its structure. In this regard the scientific polemic about development of foreign language education and methods of teaching languages is analyzed. Authors recognize the fact that the strategic objective of foreign languages training consists in development of "secondary language personality" properties of the students. In this context the communication of the concept "secondary language personality" with two types of competences that is foreign language and cross-cultural and communicative ones is proved.

The article deals with problem-situational learning using cases as a form of foreign language classes. The features of the case-method implementation in the educational process at English lessons are considered. The analysis of requirements to development and application of a method of cases in educational process is carried out. Examples of the use of situational tasks in the educational process are given.

The article is devoted to the development of a technology for obtaining organic fertilizers from poultry waste based on biocatalytic processes. Currently, many poultry farms have become sources of environmental pollution, thereby causing serious environmental problems and economic and social damage. The problem of reliable protection of the natural environment from pollution by bird droppings is currently relevant. In the area of operation of large poultry farms, air pollution by microorganisms, dust, foul-smelling organic compounds, which are decomposition products of organic waste, as well as nitrogen, sulfur, and carbon oxides, is possible. Bird droppings contain acids, nitrogen, phosphorus and potassium, heavy metals. The content of nitrogen, phosphorus and potassium changes dramatically depending on the quantity and quality of the feed. Humic substances isolated from brown coal have a sufficiently high sorption activity and are used as cheap sorbents for solving a number of environmental problems in industry. These studies are aimed at minimizing the main disadvantage of the anaerobic digestion process, the low reaction rate, which leads to the need to create large-volume bioreactors. On the basis of the research carried out, a technology has been developed for obtaining organic fertilizers from poultry waste by the method of anaerobic fermentation of chicken manure with humidity at a temperature of 27 °C - 50 °C with the addition of sodium humate. The resulting fertilizer is intended for use in agricultural production, horticulture, floriculture, forestry, municipalities, in household plots in order to increase the yield and quality of crop production. For the developed technology, an application has been submitted for obtaining a Patent for the invention of the Republic of Kazakhstan «Method for producing organic fertilizers» (priority No. 2021-22818, dated July 13, 2021). The invention allows to significantly reduce the time of fermentation, to enrich the product with organic and mineral products contained in sodium humate, to convert the salts of heavy metals into an insoluble state, to improve the environmental friendliness of the method.

Main problem: Bird droppings and animal manure contain acids, nitrogen, phosphorus and potassium, heavy metals. The content of nitrogen, phosphorus and potassium changes dramatically depending on the quantity and quality of the feed. Purpose: To study the effectiveness of the use of organomineral fertilizer from poultry waste, obtained using biocatalytic processes on the growth and development of plants. Methods: An application for a Patent for the invention of the Republic of Kazakhstan "Method of obtaining organic fertilizer" has been submitted for the developed technology for obtaining organic-mineral fertilizer. In the soil intended for growing seedlings of tomatoes of the “Pepper-shaped Orange” variety and peppers of the “Bogatyr” variety, the resulting fertilizer was applied in the amount of 1 kg per 1 m2 of soil, which was dug to a depth of 8-10 cm and used to grow seedlings in closed ground and subsequent for planting it in open ground. Soil without fertilization was used as a control. The process of soil preparation for open ground, intended for planting seedlings, was carried out for the experimental field with the introduction and control without fertilization. Experimental and control studies were carried out under equivalent climatic conditions, the scheme and technology of watering plants. In total, 100 bushes of each plant species were used in the experiment. Results and their significance: The use of the obtained organomineral fertilizer allows to increase the yield of vegetable crops (tomatoes, peppers) by 20-25% compared to the control. In addition, in the experimental samples, an increase in the number of fruits on a bush was noted with an increase in their size, a decrease in the growing season and the number of damaged fruits.
