Short-Term Response of Soil Organic Carbon Indices to Different Farming Strategies and Crop Rotation Systems in a Semiarid Warm Region

Table 2

Initial and final values of total SOC, labile-SOC, and non-labile-SOC (mean ± standard deviation) under three farming strategies and four crop rotation systems.
