Nice, thanks for the info. I ended up just making a few batches of some homemade "biochar" in an old over-sized kettle type thing hah. It was a nice deep bowl shape so as I was doing some yard work, I would add a little more litter to it and continue on with my work. I would continue adding material to it until it was about half way full of smoldering material, hoping to limit much of the oxygen working it's way down into the smoldering wood, then just let it smolder overnight or for a couple days. not truly sure what you would classify my end product as, but ended up just mixing it all into the compost bin outside. It is definitely present in the mixes I have now, but a very small amount, so I figure even if I butchered the process, it won't cause too much harm. I broke most of it up with a hammer, some pieces are still fairly large, but i am able to break these into smaller pieces by hand as I notice them and am mixing either the compost or soil mix it is in.
What is your process for "charging" it with the alfalfa and kelp? Do you just mix the kelp/alfalfa meal in with some water and let them soak together?
