The ability of agricultural soils to slow climate change is dependent upon the length of time soils can continue to amass carbon (vertical axis). The potential to increase soil carbon (e.g. soil carbon sequestration) with different land use practices is shown at the bottom of the figure, as well as their combined potential (black solid). The vertical dashed line sows the average potential soil carbon sequestration rate (0.83 Pg C year-1) for reference. The white line shows how much soil carbon sequestration would be needed to lower global temperatures by 0.1 °C. Note that the amount of soil carbon sequestration needed to slow climate change is also dependent upon the amount of background greenhouse gas emissions.
