If you are would you be kind enought o share... How did you test the soil before application? Sourced the biochar? Or home vrew? Feedstock of biochar - wood chips, cuttings, etc? How well has it worked in your garden. Really interested in anyone in the PNW, northern tier US or Alaska. Thanks in advance.
The soil test folks are out in Palmer, with the farmers (duh) - don't fell like driving 100 miles or more for some simple tests. There is a "biochar.org' that lists some activity in Ak, but the links are dead or go to 404. Hence the post here.
Yes, but I just call it charcoal. Does good things for the acidic soil around here. You can use any hardwood to make your charcoal.
If you are willing to pay for it Timberleaf soil testing is great. They have a website to order from and the test kits are sent throught the mail. I did a base test through them and now use the cheap kits in the local stores to monitor the basics. I just did the standard test. I wasn't sure that I was willing to pay for the others.

Thanks Carley Thanks for the link. As for charcoal,. biochar is a relatively high temp (900+ F) pyrolysis of 'biomass' which yields a fine grain product. The big deal, as I understand it, is that biochar is high in organic carbon and resistant to decomposition over time. Hence my question o find users in a northern tier or PNW state. Bichar, also called Terra Preta in the Amazon basin, still provides a good growing medium despite the wet environment - thus catching my interest. I had a bad potato crop two summers ago due to the wet, despite my work to have the bed well drained. I composted the patch this last summer and covered with black plastic to increase the heat in the earth - I'll test the soil pH at breakup (spring thaw) to see if any lime is needed. The biochar is supposed to hold nutrients, and help the soil resist changes in pH... I'll keep looking for a local source, thanks to all for your input!
