Natural Quench Method
by Rainer Harry Kurth
I started making bio char by fast burning dry, green whatever old rotten wood and feeding fire regularly with medium to small branches just keeping it hot and smoke free then when you have exhausted your supply of wood rake all ash and charcoal together and you will have bio char.
The final part: QUENCH FIRE FULLY USING A BUCKET DIPPED INTO A FULL 200 LITRE DRUM OF WATER OR TWO DRUMS DEPENDING ON THE SIZE OF FIRE AND I REMIND YOU TO FULLY QUENCH! NOW YOU CAN BIO ACTIVATE WITH WORM CASTING TEA, PEE ETC AND ADD TO YOUR GARDEN FOR A 50 TO 100 PERCENT HIGER YIELDS . NO BULL MANURE Hi, thanks for your comment. This sounds similar to how I now make my own biochar. We get so much waste woody material that using drums means we would be burning every day for weeks to get it done.
The only difference is that I usually use a shovel to add the embers directly to the water container. I've found that this gives a more reliable quench than dousing the fire with buckets. I had a couple of fires when I was first starting out which did not quench properly and managed to get started again - over night most of my biochar burned away to nothing!
As you say, don't forget to fertilise the biochar before you add it to your garden. Mix it into you compost heap as you add other stuff and it will absorb nutrients and micro-organisms will grow in it too.
All the best and keep on burning!
