In this paper we showed that: (1) deep-rooted perennials stimulate the transfer of more atmospheric C to both surface and subsoils than shallow-rooted annuals, (2) newly generated SOC under deep-rooted perennials is relatively less protected from decomposition, and (3) reaping the C benefits of deep-rooted perennials could require maintaining the land cover as a perennial cropping system.

Asmeret’s TEDtalk is now available online.
There’s two times more carbon in the earth’s soil than in all of its vegetation and the atmosphere — combined. Soil Biogeochemist Asmeret Asefaw Berhe shared how we could use its awesome carbon-trapping power to offset climate change. “[Soil] represents the difference between life and lifelessness in the earth system, and it can also help us combat climate change — if we can only stop treating it like dirt,” she says.
