Abstract
Soil, a lithosphere layer formed from the parent rock under the influence of soil-forming factors, is a crucial element of the natural environment. These factors, including the actions of living organisms, climate, and water, influence the ratio between the phases in the soil. The soil-forming process, which lasts all the time, is influenced by melioration, agro-melioration, phyto-melioration, and cultivation. Soil is a living environment and a source of nutrients for many species of microorganisms. It fulfils various functions in the natural environment, primarily filtering, buffering, and protecting ecosystems from the excessive flow of trace elements to other elements of the biosphere. In this system, certain toxic compounds and substances are also subject to decomposition processes into less or not all poisonous compounds. However, the properties mentioned above of soils last as long as the balance in their biogeochemical functioning is maintained. Therefore, the process of soil fertilization used for this purpose are so important. Currently, cultivated crops use traditional mineral fertilizers in large quantities, which facilitate obtaining high yields. At the same time, the excess of nutrients introduced by these fertilizers causes disturbances in the natural cycle of circulation of elements. The consequence of this process may be a violation of the biological balance of various ecosystems. This work introduces a new, eco-friendly approach to fertilization, particularly the use of glassy mineral fertilizers. These fertilizers, rich in macro-microelements, function as slow-acting mineral fertilizers with plants' self-regulated uptake of mineral components. A key advantage is that after leaching out useful components, they leave behind a completely harmless residue, compatible with the mineral components of the soil. This promotes a more sustainable approach to fertilization, reducing the environmental impact of traditional mineral fertilizers. The internal structure of fertilizer glasses is based on a silicate bond, which provides the glasses with thermal durability and chemical resistance to water. Other components modify this structure's structure and thus change the properties of the glass. In the case of glassy fertilizers, the fundamental property is their solubility, which is understood as the ability to release mineral components (i.e. P, K, Ca, Mg+ microelements) in the soil environment. Previous studies have shown that the solubility of glasses from the SiO2-P2O5-K2O-MgO-CaO system increases with the content of P2O5 and K2O while maintaining specific proportions between the remaining modifiers. Our research, conducted using DSC, XRD, XRF, MIR, ICP-OES, and SEM-EDS methods, has further confirmed this. We have successfully designed and produced fertilizers that are active in the soil, a testament to the rigorous research conducted at the Faculty of Materials Science and Ceramics of the AGH University of Krakow, a leading institution in the field of materials science.
