This study aimed to evaluate changes in selected physicochemical properties of soil resulting from a forest fire and subsequent suppression activities. The research was conducted in the Majoński Grove in Luboń (Greater Poland Voivodeship, Poland), where controlled burning of forest litter was performed to simulate fire. Soil samples were collected from three depth intervals (0-50 mm, 51-100 mm and 101-150 mm) before and after burning. Laboratory analyses included grain-size distribution, pH, electrical conductivity (EC), calcium carbonate content, cation exchange capacity (CEC), organic carbon content and magnetic susceptibility. The results indicated pronounced alterations in surface soil layers, particularly increases in pH, EC, organic carbon and oxidizable carbon, confirming that fire effects were largely confined to the soil surface. These findings contribute to a better understanding of post fire soil processes and may support assessments of forest ecosystem recovery as well as operational planning for the State Fire Service.
