First time making biochar!
10 liter bucket filled with about 3,5kg of char, mixed in four or five big handfuls of donkey manure, about the same amount of finished compost, topped off with grey-water …and I peed on it. Twice.
Now we let it rest for a while, stir it every few hours and continue to pee on it obviously.
Let’s hope our raised garden beds will love some added biochar to hold onto our precious water and feed them all the micronutrients they’ll ever need
