Charcoal in agriculture: Experimental research at Fourth Corner Nurseries
Richard Haard, Fourth Corner Nurseries, Bellingham, Washington, January 3, 2008

Greetings

I just finished over the last few days organizing images and data from my charcoal experimental plots. I am presenting a new set of posters showing root systems of the native shrub, Lonicera involucrata or black twinberry that I used as an experimental subject in these treatment plots this summer.

This will be the last of a series of piecemeal postings about my findings on the terrapreta reading list. In time, I will prepare a summary of what I have accomplished this year, the shortcomings, what I feel I have learned from this work about using charcoal and my plans for continuing this experiment for 2 or more growing seasons.

Biochar Trials at Fourth Corner Nursery
Richard Haard, Fourth Corner Nursery, Bellingham, WA, December 6, 2007
Hello All - For your interest

I submitted to Tom for posting [attached] some initial soil analysis data from my charcoal block study. In am just beginning to compile a report on this work. When it is posted you will see soil analysis results averaged for each replication(2) for 2 dates , April and October. Listed are pH, Buffer pH, OM, Nitrate, Cation Exchange Capacity (CEC) and base exchange components, % Potassium, % Magnesium, % Calcium. Other soil analysis was taken but not presented here.

Keep in mind this is a 2 to 3 year study and no additional additions or treatments will be done other than continuous cropping and harvest of all growth, tops and roots, at our bare-root native plant nursery. It is my attempt to emulate Christoph Steiner, et al research in Manaus

Bamboo Biochar Trial 2006 China
Robert Flanagan, SAFFE, China, July 2007

This is a trial we started last year using bamboo charcoal as a soil amendment. Last year we sent Cornell University soil samples last year and hope to continue this research with them in the future.

This is an image of our charcoal as soil additive study at our nursery. Shown is one of our test subjects a local native shrub that we propagate and sell for riparian restoration projects. Black Twinberry, Lonicera involucrata. This plant was a 2 year old seedling, bareroot harvested and stems clipped to 6 inches before planting in the test bed 7 weeks ago.
