- Abstract
The objective of this study was to investigate the behavior of physical attributes and soil carbon stocks in multi-stratified agro forestry system (AFS) compared to different types of land use, including cocoa plantation in agroecological management (CAC), pasture (PAS) and native forest (FLN). The treatments were installed at CEPLAC experimental station in Ouro Preto do Oeste, Rondonia State. Five plots of 20 m x 30 cm were installed at random in each of the four different land use. On those plots, disturbed and undisturbed soil samples in layers of 0 - 20 cm and 20-40 cm depth were collected for determination of physical attributes and soil carbon stock. Soil density in AFS, CAC and PAS were high and promoted negative influences on soil porosity. Soil carbon stocks were influenced by different land use modality, showing at layer 0 to 20 cm (Mg m-3): 24.79 (ASF); 42.71 (CAC); 41.30 (PAS); 36.07 (FLN), and at layer 20 to 40 cm (Mg m-3): 17.26 (ASF); 31.06 (CAC); 22.31 (PAS); 25.49 (FLN). All evaluated systems presented expected soil carbon stocks, however spatial arrangements that favor the input of organic matter may contribute to increase soil carbon stocks in agroforestry systems.
