Soil carbon stock changes following perennialization- A meta analysis

A meta-analysis on SOC stocks compared between annual and perennial crops within the same experiments by reviewing and synthesizing the existing available evidence about perennialization. The specific objectives of the study were to: (1) assess the performance of the perennial crops compared with annual crops (either as monoculture or crop rotation) in terms of SOC stock changes; (2) explore the temporal effect of perennialization on SOC stock difference compared with the effect of annual crops; (3) study the effects of abiotic factors (soil, climate, and plant properties) on the SOC stock changes.

本研究为一项元分析，通过梳理并整合现有关于多年生化种植的相关研究证据，对比同一试验框架下一年生作物与多年生作物的土壤有机碳（Soil Organic Carbon, SOC）储量差异。本研究的具体目标如下：(1) 评估多年生作物（单作或轮作模式）相较于一年生作物在土壤有机碳储量变化方面的表现；(2) 探究相较于一年生作物的影响，多年生化种植对土壤有机碳储量差异的时间效应；(3) 分析非生物因子（土壤、气候及植物属性）对土壤有机碳储量变化的影响。
