Soil carbon sponge (or soil sponge) is porous, well-aggregated soil in good health, better able to absorb and retain water. Australian microbiologist and climatologist, Walter Jehne, articulated the concept of the soil carbon sponge in his 2017 paper, Regenerate Earth
The video is shot in what looks like a local hall and the acoustics are not the best. But it is worth perservering with for the information that it contains.
You will see how a 50mm rain event can be improved from about 6 days of retained moisture in the soil to around 200 days of moisture held in the soil.
