[Terrapreta] Scientific American Story on Charcoal Decomposition

[Sean K. Barry]

Hi Lloyd,

You are right.  The carbon sequestration potential of charcoal-in-soil is only PARTIALLY offset by increased losses of carbon from humus.  So, the title of the article (not the paper) in question, ...

"Charcoal in Burned Forests No Way to Store Carbon"

might be misleading.  It almost claims that the proposed process of amending charcoal-into-soil as an effective carbon sequestration method is a non-starter.  Or am I reading way too much into NO WAY?

Regards,

SKB

  I note that the author only indicated that using Charcoal (black C) for enhancing ecosystem C sequestration ... can be "partially offset by its capacity to stimulate loss of native soil C".  The important point is that the carbon sequestration capacity of Char is only Partially Offset by losses elsewhere (from humus) ~ which would mean the net carbon sequestration potential is still positive.

          Dear Folke, 

          Pls find encl the publication text PDF.  Need to be studied more in-depthly and discussed later on. The  department of forest ecology and management, SLU (Swedish University of Agricultural Sciences) Umea  Professor David Wardle, Professor  Marie-Charlotte Nilsson and  Professor  Olle Zackrisson are high science Colleagues, and such rarely 10 long years executed study is of value and should be taken very seriously.

          The 10 year study - in relation to the evaluation of forest wild fires - is executed in the Boreal forest sites in northern Sweden humus rich forest soils  with high "dosis" 50/50 mixtures and 100% blank. The conditions and the scenario for wild fire boreal forest is very much different than for AGRO TP, which agricultural adaptation may also widely variate at different places and cultivation practices world wide. 

          The industrialized production soil-char composite products  I develop is a microbiologically pre-mobilized organic/inorganic complex fertilizers with combined effects, with successful dosis 400 kg/ha up to 1000 kg/ha in granulated form with consideration 20 cm top soil.  At this moment we have wide soil and climatic tests ongoing in Italy, The Netherlands, Germany, Israel, UK and Hungary. 

          I have distributed the publication to my Colleagues at different soil science groups at UK, NL, DE, IT Universities and for experience / knowledge exchange I will make follow up and direct discussion with the SLU Professors as well. 

          However, KEVIN may have right: "Reading between the lines of the article, one could guess at the general content of the Paper, but the article was presented in a shallow, sensationalist manner that would likely leave with the uninitiated reader with the impression that charcoal in soil was "a bad thing." "

          Do you have the pdf? Could you send it to me?
