  • Prospects of using pulp and paper mill sludge to increase soil fertility and for crop production
    (2022-2024 , Bakhmet, Olga N., , 22-16-00145)
    The intensification of agricultural production is based on the application of new economically profitable methods and techniques that provide, among others, an increase in soil fertility. Currently, agricultural practices are being actively studied, allowing, on the one hand, to maintain a high level of soil fertility, and on the other, to reduce the cost of agricultural products. A wide range of substances is being considered and studied as a partial replacement for the application of high doses of fertilizers to the soil, but the question of the possibility of using sludge from the pulp and paper industry for these purposes remains open. The aim of this project is to assess the impact of the application of pulp and paper mill (PPM) sludge (lignosulfonate, mill activated sludge, primary sludge, coniferous bark) into soils of various types (mineral and peat) in various combinations and doses on the agrochemical and physical properties of the soil and, most importantly, on the yield of a wide range of cultivated plants in open and closed ground. It is expected that PPMsludge contributes to an increase in soil productivity and fertility through an increase in the content of organic matter, mineral nutrients, cation exchange capacity, changes in the structure, density, water-holding capacity, and other soil properties. Sludge-related improvement in soil properties is expected to have a positive impact on agricultural yields. Since yield largely depends on the physiological activity of photosynthesis, respiration, and water exchange of plants, the effect of waste on their ability to activate these processes and act as hormonal biostimulant of growth is important to study in this project. However, these hypothetical statements require confirmation, which are found or refuted during this study. Thus, for the first time, the role of PPM sludge in optimizing the physiological processes of plant growth and development is revealed indirectly through the effect on soil properties, or directly through hormonal and other biostimulation.
  • Agrobiological efficiency of introduction of medicinal plants of the North into agricultural production
    (2023-2024 , Urkevich, Maria G., , 23-26-10057)
    The project is aimed at solving the fundamental scientific problem of providing pharmaceutical raw materials to the pharmaceutical base of the North of Russia in general and the Republic of Karelia in particular.
    The implementation of the concept of ecological and pharmaceutical safety of the country involves improving the existing system of agricultural technologies for growing medicinal plants by expanding the assortment of medicinal species grown in culture and developing technologies for their cultivation in the northern regions.
    Currently, a small assortment of medicinal species is cultivated on small areas in the Altai and Stavropol Territories, the Crimea and some farms of the central chernozem region of the Russian Federation. However, the significant resource potential of economically significant northern native and introduced species is practically not involved.
    At the same time, it is the use of certain types of medicinal plants adapted to the conditions of the North that is especially relevant in areas of risky agriculture, where low natural soil fertility is one of the limiting factors in the development of agricultural production.
    To ensure highly effective management of the production potential of medicinal species, it is necessary to evaluate a number of physiological and chemical responses of plants to various soil indicators, the composition of poly and monocomponent crops, harvesting time. During the research, the features of growth, development, productivity of plant raw materials will be revealed. This project will assess the economic effectiveness of growing medicinal plant raw materials in depressed northern regions.
    The project is interdisciplinary and interregional in nature. For the first time, a comprehensive assessment of the impact of various agricultural practices and soil conditions on the possibility of stimulating the physiological reserves and chemical composition of plants, and as a result, an increase in the overall productivity of medicinal plants and an increase in the profitability of production will be given. The new data obtained during the implementation of the project will be of both fundamental and applied nature.
