Biological pathways to carbon rich soil, by Dr Christine Jones.

A treasure trove of scientific information from one of the world’s foremost soil scientists was shared recently on a video link from Australia, arranged by Otago University.

Dr Christine Jones, in video and written material, gave us practical insights to the pathways of a carbon rich soil. From the fundamentals of the soil biome, to why mass plantings of Pinus radiata can produce a negative carbon result over the long term.

I know there is too much material here from Dr Jones for a single posting, so be prepared to digest over several sittings. Put aside an evening instead of watching the news on tele. You will be amazed at what you hear and see.

For instance, Dr Jones explains how the subsoil, not the topsoil, from 20 cms below ground down to 1 metre, holds more carbon than the top 20 cms. And the entire world’s soils contain three times the carbon that the vegetation on top of the soil does.

“Soil is by far the largest sink for carbon on planet earth,” according to Dr Jones (abridged).
