Our dataset encompassed 95 independent study sites investigating the effect of land conversion to alfalfa on SOC content at the global scale (Fig. 1). The funnel plots of cropland-alfalfa and abandoned-alfalfa were generally symmetrical (Fig. S2), indicating that data quality standards of the meta-analysis were satisfied. Overall, land conversion to alfalfa enhanced SOC content by 12.8 % (95 % confidence interval (CI), 9.0 % – 16.8 %, P < 0.05, Fig. 2A), while cropland-alfalfa and

As a perennial forage crop, alfalfa ( Medicago sativa L.) has been extensively utilized for the vegetation restoration of degraded soil and provides feedstock for forage. Its high usage can be attributed to its high yield potential and the increasing soil organic carbon (SOC) sequestration of alfalfa cultivation. However, the impact of land conversion to alfalfa on SOC content and its underlying drivers remain unclear. We performed a meta -analysis at the global scale to explore the quantified effects of alfalfa cultivation on SOC content and identify its controlling factors. We employed 1699 ...
