In this episode, I talked to Prof Pete Smith, one of the world’s renowned academics on soil carbon sequestration.
In this podcast, Pete gets into the details around soil carbon – what it is, how to measure it, and whether it’s all it’s cracked up to be, as a solution to climate change.
Pete tells us that the science is settled on the agricultural practices that increase soil carbon. But he explains why it’s “not quite there yet”, as an investable asset, and why the big opportunity will be in arable soil, not grasslands. He also explains the big commercial opportunity that he sees for start-up companies trying to crack the biggest “game-changer” problem in soil carbon today – which is how to measure carbon levels in the soil quickly, cheaply, at scale.
Finally, Pete talks us through the benefits of regen agriculture, including practices like min till, cover crops and diverse rotations, explaining why he's in favour of England’s prospective Environmental Land Management scheme.
