Chapter synopsis: The adoption of Conservation Agriculture (CA) and the maintenance of crop residues on the soil surface result in the long-term increase of carbon (C) in the system, promoting C sequestration and reducing C-CO2 emissions to the atmosphere. The present study conducted in subtropical and tropical regions in Brazil aimed to assess the impact of the continuous plow-based conventional tillage (CT) on soil organic carbon (SOC) stock vis-à-vis native vegetation (NV) as baseline, compare SOC balance among CT, CA cropping systems, and NV; and evaluate the redistribution of SOC stock in soil profile in relation to soil resilience.
