Figure 7 Zhou (2026): Conceptual diagram of the effects of grazing exclusion on the stocks of soil organic carbon fractions across two soil depths. Soil organic carbon (SOC) fractions include particulate organic carbon (POC) and mineral-associated organic carbon (MAOC). The percentage changes in SOC fractions represent the variations of the two grazing exclusion treatments relative to grazing across 0–30 cm soil depth. For the other predictor variables, the percentages represent the mean changes of the two grazing exclusion treatments relative to grazing, calculated separately for the 0–10 cm and 10–30 cm soil depths. Orange arrows denote positive effects, while blue arrows indicate negative effects. Ox:Hy ratios, oxidative-to-hydrolytic enzymes ratios.
