Sapropel is natural organic material, which is used in many industries, such as agriculture, medicine, pharmaceutical, manufacture of energy carriers and building materials. However, the widespread use of sapropel is associated with its high hydrophilicity and moisture capacity, leading to technological difficulties with sapropel dehydration to required humidity, depending on its further application. The article discusses various aspects sapropel beneficial application, primarily the advantages of the use of sapropel as a fertilizer for cultivated areas, and for the reclamation of industri-al wastelands and mined lands. As a part of this study, experimental research of the qualitative and quantitative parameters of sapropel of Savelievskoye field of the Yaroslavl region was conducted. Based on the results of this research, the nature of the high hydrophilicity of sapropel of Savelievskoye field and the possibilities of reducing its humidity for the production of fertilizers is revealed.

According to the presented results of the study, the responsiveness of varieties to the application of different doses of mineral nutrition was more significant compared to the sowing dates. Doses of fertilizers N60P30K60 and N90P30K60 increased the barley yield of varieties Takmak, Abalak, Buyan and a promising sample D-5-7022 by 1,2-1,8 t/ha, weight of 1000 grains by 2-6 g, germination - by 1-4 % as compared to the control (without fertilizers). The Buyan variety exceeded the yield of all the varieties studied by 0.2 t / ha on a fertilized background and in this group proved to be intensive (increase in yield to control - 1.8 t / ha, bi (linear regression coefficient of yield) = 1.34). The yield of the new sample D-5-7025 was 0.3-0.4 t/ha higher than the released varieties in the control without fertilizers. With fertilization the yield of Abalak, Takmak varieties leveled off to an average of 5.68 t/ha at N60P30K60 and to 5.85 t/ha at N90P30K60. They are less demanding to the conditions of cultivation and more plastic. Elements of yield structure, productive stem, ear grain content and 1000 grains weight generally influenced its increase in the second sowing term on intensive agricultural backgrounds. The size of the development of seedlings, as well as the yield was less dependent on the sowing dates, but more on the application of fertilizers. At a dose of N90P30K60 all indicators of seedling development increased by 1.2-2.5 cm compared with the control. The use of optimal sowing date (May 27) with the sum of active temperatures of 182,8о and the recommended dose of fertilizers N90P30K60 made it possible to increase the yield of barley seeds of Takmak, Abalak, Buyan and the new sample D-5-7022 on average by 20-30 %.

Abstract. The purpose of the research is to comprehensively assess the resource potential of agricultural organizations in the Kurgan region to form the trajectory of their development and determine the contribution to agricultural production in the region. Methods. The study was based on the use of statistical and econometric methods for collecting, processing, modeling data. It is based on the assessment of the use of the following functional components of the resource potential: land, material and technical, personnel, innovation and financial. At the same time, the dynamic assessment for each subspecies of the resource potential gives an idea of the trend in the volume and level of resource use, and the stochastic assessment – to identify the relationship between the indicators of resource investment and their return. Results. The presented assessment of the existing relationships between the quantitative and qualitative indicators of the resource potential and its subspecies indicate, on the one hand, an acute shortage of certain types of resources, and, on the other hand, an increasing intensity of their use without a proportional level of return. The study allows us to conclude that it is necessary to develop levers for managing the resource potential of agricultural organizations based on the symbiosis of the needs of agricultural producers and the territory in which they operate. Scientific novelty. The research methodology allows combining several methods of assessing (dynamic and stochastic) in achieving the final result, as well as assessing the elasticity between the general level of resource productivity of agricultural organizations and indicators of the efficiency of using the main types of resources. This approach makes it possible to form a sequence of actions to ensure an increase in the level of development and use of the resource potential of agricultural organizations.
