Abstract

The aim of this study is to explore the impact of the main determinants on the rapid increase in fertilizer prices in Poland and to foresee the consequences of this situation regarding sustainable policy developments. We developed linear regression models for N, P, and K fertilizers to show the direction of influence of explaining variables and make a decomposition of the fertilizer price increases. The models illustrate that four major factors were responsible for the fertilizer price increases in Poland in 2020–2022, i.e., wheat, gas, GHGE allowance prices, and domestic production volumes. These factors explained the variation in the price of fertilizers concerned with different strengths. There were also other impacts associated with the 'black swans' occurrence (the COVID-19 pandemic and the war in Ukraine). High mineral fertilizer prices provide an opportunity to revise agricultural policy and legislation, taking into account environmental concerns and the latest technological developments. Fertilizer management practices are at the center of a triangle of critical objectives that track the progress toward sustainable agricultural systems, such as (1) an increase in farm incomes, (2) environmental protection, and (3) food and nutrition security. We recommend adjusting the set of explaining variables in the models (i.e., wheat/corn price) to the specificities of the domestic agri-food system. This study provides important guidance for agricultural policymaking, emphasizing the need to integrate sustainable fertilizer management practices to achieve synergies between economic growth, environmental protection, and food security. Such an approach can support the long-term development of agriculture in Poland and contribute to the economic and environmental stability of the agricultural sector. [ABSTRACT FROM AUTHOR]

Abstract

The magnetic field (MF) effects resulting from water or solution treatments are still of significant interest. However, a relatively small number of papers have been published dealing with the pure surfactant solutions alone. On the other hand, surfactants are applied in many industrial processes as well as in everyday life and are also present in different waste waters. Therefore, it seemed interesting to investigate whether some effects would appear after the MF treatment of pure aqueous surfactant solutions. In the earlier published papers after MF action the changes in water evaporation rate and the surface tension were found for both the cationic dodecyltrimethylammonium bromide (DTAB) and anionic sodium dodecyl sulfate (SDS) solutions. The gradient MF originated from three connected ring magnets inside which the solutions were placed. The objective of this paper is to study whether using the same magnets but in a different position the effects of the MF are observed. The given surfactant solution in a closed vessel was placed in an uniform MF when the magnets were in the "lying" position. The investigated solutions on the magnet surface remained for 24 h. In this paper, despite SDS and DTAB also the cationic hexadecyltrimethylammonium bromide (CTAB) and nonionic Triton X‐100 solutions were applied. It appeared that in the uniform MF the surface tension of cationic and anionic surfactant solutions changes. However, larger changes were observed in the gradient MF. Generally, the changes of surface tension depend on the surfactant kind and its concentration. Stronger MF influence was found for the cationic surfactant and almost no changes were observed for nonionic Triton X‐100. [ABSTRACT FROM AUTHOR]
