  1. Could you please explain what you mean by "breaking down" in a few years? Sorry I have to ask, but all the scientific literature I've been reading indicates the benefits last for several hundred years. I'm also curious about why you're not using an air pump to inoculate the slurry and feeding it with flour or molasses. Seems like that's the way most people do it. My understanding is that oxygen is required to keep if from going anaerobic and populating the char with "bad" bacteria.

  2. There’s a horticulturalist on YouTube who vehemently maintains that charcoal and biochar are not the same substrate. Both comprise carbon, but biochar has a distinctly different physical structure, and it is this structure which gives biochar it’s efficacy as a soil amendment. If you conflate charcoal with biochar, take a moment to watch his cogent presentation: https://youtu.be/LWg1fm6Ss1M

  3. The Kingston Brick charcoal (blue bag)is the best charcoal to use as biochar, if you immerse it in water, the bricks will dissolve easily with little effort in manually crushing it, if you use lump charcoal, it is just a too hard crushing it. Mix cow manure to load the biochar.

  4. The main difference between this type of charcoal and agricultural biochar is the presence of volatile organic compounds. That's why Royal Oak burns and biochar does not. Some of the VOCs in BBQ charcoal are really nasty. Two of the worse are toluene and formaldehyde. Both of these compounds are highly toxic and soluble in water. That's why there have been many papers published warning against using charcoal that contains VOCs for soil amendment.

  5. About six months from the time you made that video, I decided to try mixing biochar into my potting soil., so I did what you did. there's a dollar general in my neighborhood. I needed to break the charcoal into bits that would go through a 7mm sieve… in my apartment. What I did was to lay an old brick in the bottom of a cardboard box, cut a small hole to fit the end of my shop vac hose, cut a larger hole to fit my hand through and went to work with a 2 lb. short-handled sledgehammer. The vac pulled out the dust from crushing, but sifting made more, and my hands were filthy up to the elbow. Ugh. I used the charcoal that was left in the bag for the barbecue, then went online. When I looked for horticultural charcoal, it cost way too much. I also saw aquarium filter carbon. Still way too expensive. What I finally found, still expensive, but not so bad, was coconut shell charcoal sold for filling air filters. That's what I've been using ever since. I only need a little bit, (about a pint to a bushel of soil mix) so a ten-pound bag lasts me over a year.
