Field trials

Josiah Hunt, July, 2010

Josiah has a background in Agroecology and Ecology, and he has been working both in landscaping, and in making Biochar. See his web site for more details http://www.landscapeecology-hawaii.com/

His work is also noted in the July-August 2010 Audubon Magazine Field Notes: Please Smoke

I'm slowly catching up on all the things that I had to place on hold while I was in Haiti. Haiti, and the up coming tests in other countries are clearly providing a wide range of of verifications into the effectiveness of biochar as a soil amendment. As valuable as field work is, there is something to be said for the opportunities to control the environment so as to isolate a few variables.


I am very lucky to have a great team working with me and wanted to share a bit of how it's going. (more updates soon)

Field Trials;
 I am field testing for the 09 corn season with JMU and consultation  Dr. Hepperly at Rodale Institute.

Ten research priorities were identified at the IBI conference, The following priorities I hope to address:
• 1- Economy research/market research
• 2- plant+soil research depending on biochar
• 5- field trials
• 8- application to soil (depending on agricultural or other
systems/remediation`)

Planting date: June 24th.
Two split plots , which each are split into a 20% (27 tons/Ac) & 5% (7 tons/Ac) application rates,
All chars soaked in tarps for 1 month, all chars were mixed 1:2 by volume with finished poultry litter compost and roto-tilled to 5 inch depth.

Third year results: Fourth Corner Nurseries Soil/Biochar Study

This study predates the coining of the term biochar and I claim grandfather rights to use the word charcoal.

Summer 2009 Biochar plot studySummer 2009 Biochar plot studyresults are showing some trends I have had difficulty measuring with the last two years of cropping these plots. The use of buckwheat, a short season cover crop plant makes a visual view of performance reflecting nutrition, quite vivid. In spite of the dips in the plots due to deer browse.

This image is a merged sequence of pictures taken at same distance. Background may be confusing because of perspective. These plots are the first set, (south end), of treatments laid out in a systematic way. Results from the north set are similar and will be presented in a final poster

This plot study included: compost ( a wood based commercial compost of sewage solids)
charcoal 1 ( about 1/2 inch minus), charcoal 2 ( powder from John Flottvik's pyrolyser).
fertilizer: a complete, chemical fertilizer

In Our state We are having 70% Forest .Mainly Pine forest in every summer it is cause of forest fire . We face huge loss of trees, properties and life too.This is cost to Forest department . We develop the method to convert pine needle into CHARCOAL BRIQUETTE. Which use as cooking fuel. Now they are not cutting the tree for fuel.Save the forest use this method. This low cost method. for rural area. Apart of that it is produce local emplyment. Get the chrcoal with cutting tree.Like

Terracarbona.com - A New Website for the Promotion of Biochar Research and Experimentation
Chris Braun. February 27, 2008

A new website for the promotion of biochar research and experiments was born !
http://terracarbona.com

You can there discover several biochar-related projects, most of them still in active development . If you are performing biochar soil amendmend trials yourself, your contribution to CharDB or to the Field Trial Portal would be highly appreciated!
And if you haven't done it so far but would like to start experimenting, you can also find useful resources, links and contacts to help you.

This website is still in its infancy and any constructive comment, critic, question, advice... is very important for further development ! For that you can use the devoted forum:
http://z15.invisionfree.com/CharDB/index.php?showforum=2

Thanks for your contribution!

Sincerely yours,
Chris

CharDB 1.0 released!
Cristelle Braun, January 19, 2008

Hello dear biochar testers!

The first release 1.0 of CharDB is now available at:
http://bionecho.org/terrapreta/chardb/index.php

You will now be able to register your biochar soil amendment trials in a uniform format "CharML" that should facilitate comparisons between the different entries. This will hopefully lead to interesting new conclusions and a better knowledge on the fascinating world of biochar!

Please send any comment, critic, suggestion...to:
chardb@bionecho.org

Your feedback and comments will guide further development of CharDB and CharML!

Sincerely yours,
Chris
