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

The first shot is of the red Georgia clay before and after charcoal had been tilled in two years prior. The second shows some "structure" as a result of the charcoal treatment. The untreated had become very hard (compacted).

Three and four illustrate how tilth was improved. In both shots Danny
