Abstract: Abstract Quantifying soil attributes in agroforestry reflects its productivity and carbon dynamics which indicates a healthier ecosystem functioning toward achieving sustainable production of coffee in the Southern region of Chhattisgarh. The present study was carried out in the coffee-based agroforestry system (AFs) of the Darbha Block, Bastar region in Chhattisgarh. The objective of this paper was to analyze soil properties and carbon dynamics of soil under five varietal treatments of coffee-based AFs. Silver oak cultivation was added to the AFs as it protects coffee and helps in sustainable coffee production. The soil was collected randomly using the auger from two different depths viz., 0–15 and 15–30 cm under coffee-based AFs. The value of N, P, K, S, B, Zn, C, Fe, Mn, OC%, and SOC stock were higher in San Ramon (T3) based AFs. The values of bulk density (BD), pH, and EC were recorded as highest under control treatment (To), respectively. Soil organic carbon (SOC) stock ranged between 10.21 (T0)–13.86 (T3) and 0.34 (T0)–0.59 (T3) t ha−1 for surface and sub-soil, respectively. Data analysis revealed the isolation of six PCA (principle component analysis) from the various soil attributes. The first component reflected maximum variability for both layers. Further, correlation studies revealed a strong association between the soil attributes. Therefore, the present work highlights the importance of agroforestry systems towards improving soil quality along with sustainable production of coffee.
