Thanks. That was a very clear explanation.I followed the link to the article and couldn’t find much but was able to read the comments.
It looks like they are talking about carbon content of the soil which will tend to plateau somewhere below 10% and is easy to measure. What is not so easy to measure is the volume or depth of carbon containing soil and the profile of carbon content throughout that soil.
Common sense and a fair understanding of the carbon cycle along with having seen the depth of topsoil in, for instance, unploughed prairie soils makes me think as land is grazed regeneratively and the plant population diversifies to include deeper rooting plants that the depth of carbon containing soil would increase, both deeper down into the soil profile and above the original surface level as decomposing plants are processed by soil life into new soil.
In short the %age of carbon in the soil may plateau but the amount of soil will continue to increase with good management.
