World soils, a large reservoir of reactive carbon, moderate the global carbon cycle,
atmospheric chemistry, radioactive forcing and ecosystem services; as such, soil carbon …

Soils contain vast reserves (∼ 1500Pg C) of carbon, about twice that found as carbon
dioxide in the atmosphere. Historically, soils in managed ecosystems have lost a portion of …

Soil-based initiatives to mitigate climate change and restore soil fertility both rely on
rebuilding soil organic carbon. Controversy about the role soils might play in climate change …

World soils have been a major source of enrichment of atmospheric concentration of CO 2
ever since the dawn of settled agriculture, about 10,000 years ago. Historic emission of soil …

Soil carbon sequestration could meet at most about one‐third of the current yearly increase
in atmospheric CO2‐carbon, but the duration of the effect would be limited, with significant …

Soil carbon (C) is a dynamic and integral part of the global C cycle. It has been a source of
atmospheric carbon dioxide (CO2) since the dawn of settled agriculture, depleting more than …

The increase in atmospheric concentration of CO2 by 31% since 1750 from fossil fuel
combustion and land use change necessitates identification of strategies for mitigating the …

T he atmospheric abundance of carbon dioxide (CO2) has increased by 36% from 280 ppm
in~ 1750 to 381 ppm in 2006 with an annual rate of increase during the 2000s at 1.93 ppm …

The increase in atmospheric concentration of carbon dioxide from 278 ppm in the pre-
industrial era to 405 ppm in 2018, along with the enrichment of other greenhouse gases, has …

The carbon sink capacity of the world's agricultural and degraded soils is 50 to 66% of the
historic carbon loss of 42 to 78 gigatons of carbon. The rate of soil organic carbon …
