Carbon for soils, not soils for carbon
Global Change Biology, 2023 AbstractThe role of soil organic carbon (SOC) sequestration as a ‘win‐win’ solution to both climate change and food insecurity receives an increasing promotion. The opportunity may be too good to be missed! Yet the tremendous complexity of the two issues at stake calls for a detailed and nuanced examination of any potential solution, no matter how ...
