Some sentences are overly long or repetitive. Consider: Forest fires induce significant environmental changes, with long-term impacts on forest ecosystems and soil properties. These changes affect soil temperature, chemical composition, organic matter content, and microbial communities. This study investigates the alterations in silvicultural properties of Gray Forest soils (Gray Luvisols) in Northwestern Bulgaria following forest fires, considering key variables such as fire type and intensity, time since fire, forest type, and stand density. The results show that forest fires generally reduce soil organic matter and total nitrogen content, alter soil acidity, and affect soil microbial abundance. In particular, low-intensity fires may stimulate microbial activity, whereas high-intensity fires tend to suppress it. These findings provide insights into the mechanisms of post-fire soil transformation and offer a scientific basis for afforestation and land reclamation planning in fire-affected forest areas.
