Evaluating SOC lability is crucial for sustainable agriculture policies and environmental quality. This study assessed the impact of well-stocked forest cover on pools compared to shrubby soil. Geo-referenced soils under Red pine (Pinus brutia), Black nigra), Cedar (Cedrus libani), Fir (Abies cilicia), Juniper (Juniperus excelsa), Oak (Quercus L.), Carob (Ceratonia siliqua), degraded shrubs were collected from a depth 0 30 cm in Seyhan River Basin, Mediterranean Turkey. The analysis soil organic carbon (SOC), AC (active carbon), PC (passive carbon) analyzed understand management across diverse vegetation types. forests have highest (27.98 g/kg) (27.35 g/kg), followed by (SOC: 27.64 g/kg, PC: 27.05 26.44 25.85 g/kg). Shrubby areas lowest (4.06 (3.61 had CLI (1.16), suggesting relatively higher proportion labile than other forests. CPI indicates greater storage capacity (1.09) shrublands (0.18), with also having CMI (0.83). findings emphasize critical role forests, especially sequestration climate change mitigation within Basin

Understanding the spatial distribution patterns of soil organic carbon components in Ecological Vegetative Slopes (EVS) is crucial for optimizing restoration strategies, enhancing sequestration capacity, and scientifically evaluating rehabilitation effectiveness. It an important pathway promoting sustainable development. This study investigated effects slope gradient, position, vegetation type, cement content on characteristics total (TOC) its (readily oxidizable (ROC) dissolved (DOC)) through model experiments laboratory analyses. The key findings revealed that (1) TOC, ROC, DOC concentrations decreased with increasing gradient upper positions, steeper slopes amplifying positional exhibiting surface-layer accumulation characteristics. (2) highest was achieved mixed planting Bermudagrass Magnolia under a substrate thickness 3 cm 3% content. Lastly, (3) pH increased showing systematic variations across types contents. Comparative analysis demonstrated composition dosage effectively enhanced SOC accumulation, while position dominated heterogeneity distribution. These results provide theoretical practical guidance precision management ecological restoration. robust data support sustainability engineering enhancement storage.

The Role of Forest Conversion and Agroecological Practices in Enhancing Ecosystem Services in Tropical Oxisols of the Amazon Basin

Forests, Journal Year: 2025, Volume and Issue: 16(5), P. 740 - 740

Published: April 25, 2025

This study evaluates the effectiveness of agroecological practices—organic fertilization and biofertilization—in enhancing ecosystem services in agroforestry pasture systems. A field experiment was conducted over three years, comparing these practices to a control treatment natural as reference. Soil chemical, physical, biological parameters were assessed, including soil organic carbon (SOC), microbial respiration, root density, gene abundances key groups (Archaea, Bacteria, Fungi). Organic resulted significant increase SOC, phosphorus, biomass, indicating improved structure fertility. Biofertilization showed selective effects, promoting archaeal abundance but reducing bacterial fungal diversity. Seasonal variation influenced nutrient cycling, with buffering against dry-season declines activity availability. Aboveground dry biomass litter deposition highest ecosystem, followed by treatments Despite improvements under management, consistently maintained superior quality resilience. The findings highlight that inputs diversified cropping systems enhance health do not fully replicate ecological benefits undisturbed forests. In conclusion, provide viable alternatives mitigate degradation sustain tropical Oxisols. emerges most effective strategy, fostering long-term fertility dynamics. However, continued research is needed optimize for greater resilience sustainability Amazonian agroecosystems.
