Total SOC accumulation rate (t C ha−1 year−1) and SOC sequestration rate (t C ha−1 year−1) at three soil depths under different fertilization treatments (NPK and 2NPK and NPKM). In each panel, different uppercase letters denote significant difference between accumulation rates and lowercase letters show difference for sequestration at p < 0.05
