We tried several different methods, but ended-up having to develop our own equipment and techniques. A couple of these methods show promise for commercial-scale work, I believe. Basically our approach involves a few components:

• tractor-powered (PTO) spray equipment with water tank, pressure adjustments
• root-injection sonde (available commercially, but we ended-up making our own)
• slurry tank with a Venturi pump, mixing equipment
• various hoses and connections
• a lot of trial and error…

A lot of the success of this type of method is related to the choice of biochar and the formulation of the slurry. We’re continuing work this summer to try to improve these methods for larger scale commercial work, but are also evaluating, of course, whether the use of biochar applied in this manner will have any effect on the crop quantities or quality.

JF Biocarbon developed a portable pyrolysis unit for demonstration purposes, as well as larger pyrolyzers that convert beetle killed wood into biochar and bio-oils. See the attached presentation for details.

From the detail

• JF BioCarbon will enhance and promote faster growth for newly planted seedlings thus making for stronger start to a new forest.
• This will also speed up reforestation in beetle effected areas.
• Charcoal in soil also acts as a carbon sink and can qualify for carbon credits.
• This has been proven by soil scientists. (see Terra Preta & biochar)
• Using charcoal in soil will also minimize the need for engineered fertilizer.
