Graphical Abstract (IMAGE)
Caption
Preserved forests of Ocotea porosa exhibited improved soil functionality with higher levels of soil organic matter (6.56%), exchangeable cations (e.g., Ca2+ at 3.87 cmolc kg−1), and enhanced physical properties, such as soil aggregation, than degraded forests in the Atlantic Forest biome. In preserved forests, microbial activity, total glomalin (5.79 mg g−1), and organic acids like oxalic (80.19 μmol g−1) and malic acids (4.93 μmol g−1) were notably higher, indicating more active soil biochemical processes that support nutrient cycling and ecosystem health. Chemodiversity of dissolved soil organic matter (SOM), with significant contributions from carbohydrates (29.41%), lipids (20.04%), and proteins/amino sugars (41.73%), was significantly higher in preserved plots, demonstrating a positive correlation with soil quality and functionality. Preserved and degraded plots exhibited distinct arbuscular mycorrhizal fungal (AMF) communities, with Acaulosporaceae and Gigasporaceae more prevalent in preserved plots, while degraded plots were associated with Claroideoglomus claroideum, Funneliformis mosseae, and Rhizophagus intraradices.
