Meta-analysis reveals key drivers of soil organic carbon recovery after planting forests on agricultural land, highlighting the benefits of broadleaf trees and high-clay soils.

Key Points

Determine the primary environmental, management, and biological factors governing the restoration of soil organic carbon stocks following the afforestation of agricultural land.
Synthesized data from 33 publications covering 120 sites and 189 observations of post-afforestation soils.
Evaluated the effects of prior land use, tree species, soil texture, preplanting disturbance, and climate zones on soil organic carbon stocks using a mixed linear model.
Soil organic carbon accumulation was higher in converted cropland than in pastures or grasslands, in clay-rich soils (>33% clay vs. <33%), and under broadleaf species compared to conifers.
Afforestation with pine species resulted in no net loss of whole soil-profile carbon stocks relative to initial agricultural levels when accounting included the surface organic layer.
Minimizing preplanting disturbance accelerated soil carbon recovery, whereas plantings in the boreal climate zone showed small carbon losses relative to other climatic regions.
