Dear Jacki
 
I have been involved in the utilisation of charcoal for agriculture now for 20 years and am a founding member of the International Biochar (Agrichar) Initiative.

 

http://www.iaiconference.org/

www.biochar.org

 

I have been asked to give a talk to the Compost Section of our local Waste Management Association.  I would like to include photos/data from the work that is being undertaken on pit composting with charcoal.

 

Would this be okay and could you email me photos in JPEG and or documents in word, PPP or PDF,

 

I am more than happy to send you a copy of my presentation when it is finished.

 

Thanking you for your assistance.

 

Regards

Stephen Joseph

Hello Stephen,
 
If you are referring to the original document I submitted for consideration by the group participating in this seminar, I encourage you to use whatever you would like. My intention is to promote experimentation in the process of reproducing dark earth soils.
 
I visited the web site for the International Agrichar Initiative 2007 Conference. This effort is a welcome development. I hope you are successful in in your eforts with this group. I have one criticism of their view, however, which I have repeatedly come back to during this seminar.
 
On the openning page for the conference it states: "The use of Agrichar in soils mimics the Terra Preta." This implies that simply incorporating charred biomass into the earth will mimic the dark earth soil. I hope that any use to which you put the document I submitted results in a new vision for those involved in this gathering next year. Dark earth soils are fertile because of the humus in the soil as much as due to the charred material. Charring does not produce humus. Slow decomposition, mainly by anaerobes, produces humus.
 
I will send you the original photos directly to your E-maol address. But, I think they will be as good if you copy them from the Word Document.
