From a post by Toby Hemenway on FedBook:
Some amazing news on the soil science front. Humus doesn't exist. Several recent articles are showing that humic and fulvic acids and many of the other humic components of soil are artifacts of the alkaline treatment that is used to measure humus content, and don't, in fact, exist in untreated soil. When OM is measured using non-destructive methods such as NMR spectroscopy, no humic compounds can be found. Organic matter does not degrade into "stable" humic components, it simply decomposes into a continuum of smaller and smaller carbon compounds. There is constant, slow turnover of carbon in soils, not a semi-permanent trapping of carbon into "humus." Humus, meaning a stable form of carbon visualized by alkaline extraction, seems not to exist. It's an artifact of the lab method. This is kind of blow-away news for those of us who teach soil science--and it's a good lesson on how the methods we use determines what we see. Teachers, start revising how you teach soils, and stop talking about humus. Most of the articles on this are behind journal paywalls, but some of the abstracts are available. One article is Lehmann, J.; Kleber, M. (2015-12-03), "The contentious nature of soil organic matter", Nature 528:60-68. There is a short video based on that article linked below. https://www.youtube.com/watch?v=-n6emCNEmKg -- *In order to change an existing paradigm you do not struggle to try and change the problematic model /* *You create a new model and make the old one obsolete /* *That, in essence, is the higher service to which we are all being called. //* Buckminster Fuller
Hi Adam Not sure if you received my previous email about this. Just wondering if you'd be interested in taking part in Farm Hack Scotland 1st & 2nd Oct at Tombreck Farm. We now have some funding to cover travel and expenses for all workshop leaders. Info and tickets here: http://www.commongoodfood.org/whats-on/farm-hack-scotland We're keen to have some soil hacks on the go. Would you or anyone else who is active in the Soil Hack network be interested in coming up that weekend? It would be great to have a session on Actively Aerated Compost teas and/or biochar kilns, or we could have a chat about other ideas. We're making some decisions about the programme next Monday night so would be good to know if you are free.

Monday 1st. I won't be at this meeting but can get word to Fergus and Mags at Common Good Food, if you're up for coming along. They'll be working on the programme. Happy to have a quick chat on the phone tomorrow if this would be useful. I'm free at 1pm-2pm or 3pm-4pm Cheers *Clementine Sandison* *Artist, food activist and **member of Open Jar Collective* Tel: +44 (0)7971027963 Email: [email protected] Web: www.clementinesandison.co.uk Twitter: @clemsandison On 28 July 2016 at 15:29, Adam Ormes Court <[email protected]> wrote:

Hi Niels, Are you interested in presenting? If we were to come we could bring a small biochar stove and maybe a microscope and talk about them... would you be up for talking about cover crops and compost teas?
