The Conversation: How agriculture can make the most of one of the world’s biggest carbon stocks, soil
It’s right under our feet. We barely notice as we go about our lives, yet it is nothing less than the largest carbon repository among all of Earth’s ecosystems. This distinction is awarded neither to forests, nor to the atmosphere, but to our soils. There are around 2,400 billion tons of carbon in the first two metres below ground, which is three times as much as in the atmosphere.

In our era of climate disruption, there is much to be learned from soil’s impressive capacity for carbon storage. While soils on their own cannot drastically reduce greenhouse gas concentrations in the atmosphere, they can still play a substantial role by keeping sizeable stocks of carbon underground, as well as through the restoration of degraded lands. Today, a number of farming practices are helping trap more carbon below the ground. Here’s how.
