Soil organic matter (SOM) provides vital services to humanity. Its preservation and further
accrual are key to sustain food production and avoid an irreversible climate crisis. Here we …

Over 70% of soil organic carbon (SOC) is stored at a depth greater than 20 cm belowground.
A portion of this deep SOC actively cycles on annual to decadal timescales and is sensitive …

Soil is the largest terrestrial reservoir of organic carbon and is central for climate change
mitigation and carbon-climate feedbacks. Chemical and physical associations of soil carbon …

Radiocarbon dating uses the decay of a radioactive isotope of carbon (14C) to measure time
and date objects containing carbon-bearing material. With a half-life of 5,700±30 years …

Soil organic carbon (SOC), as the largest terrestrial carbon pool, plays an important role in
global carbon (C) cycling, which may be significantly impacted by global changes such as …

Soils contain more carbon than the atmosphere and vegetation combined. An increased
flow of carbon from the atmosphere into soil pools could help mitigate anthropogenic …

Understanding the controls on the amount and persistence of soil organic carbon (C) is
essential for predicting its sensitivity to global change. The response may depend on …

Elucidating the processes underlying the persistence of soil organic matter (SOM) is a
prerequisite for projecting soil carbon feedback to climate change. However, the potential …

Identifying controls on soil organic carbon (SOC) storage, and where SOC is most
vulnerable to loss, are essential to managing soils for both climate change mitigation and …

Soil organic matter decomposition and its interactions with climate depend on whether the
organic matter is associated with soil minerals. However, data limitations have hindered …
