Abstract
Climate change mitigation through soil carbon sequestration has garnered significant global interest, particularly in regions facing rapid land-use transformations. This study evaluates and compares soil physical, chemical, and biological properties, including soil organic carbon (SOC) stocks, across three contrasting land-use systems: Natural Forest, Agri-silviculture, and Silvipasture in Pasighat, Arunachal Pradesh. Soil samples were collected at depths of 0–15 cm, 15–30 cm, and 30–45 cm, and analyzed using standard methodologies. Results indicated that Natural Forest soils exhibited the lowest bulk density (1.20–1.30 g/cm³), highest porosity (55–50%), and highest SOC content (3.00–2.50%) and carbon stock (54.00–146.25 t ha?¹), highlighting their superior carbon sequestration potential. Agri-silviculture soils showed higher EC, lower CEC, and lower nutrient concentrations, largely due to frequent tillage and reduced organic inputs. Silvipasture presented intermediate values for most parameters, demonstrating the dual benefits of woody and livestock-derived organic matter. Macronutrient concentrations (N, P, & K) and CEC decreased with soil depth across all land uses. The findings underscore that undisturbed natural forest systems are highly effective in storing soil carbon, while agroforestry systems like Silvipasture offer a sustainable compromise between productivity and ecological restoration. This study provides empirical evidence for promoting land-use strategies that enhance carbon storage, improve soil quality, and support climate-resilient land management.
