Acts like a condominium for microbes. I saw a stat somewhere that the structure of char has so much surface area because of how it's created. Something like every teaspoon of char has the same surface area of a football field. That surface area is spread out over microscopic holes that are perfect for microbes. Soils rich in biochar hold the fertility for thousands of years. Research Terra Negra (Black Soil) which originated in your part of the world.
Black soil is that heavy black clay soil with all the volcanic ash that I tried opening up (with coco coir and Perlite) at the start of this thread (on page one).
It seems there is a covered grow site near here, and they seed straight into this soil (probably they till it, but I don't know).
Apparently it makes a great ground soil, but not good for pots. And so I tried to open it up, but not nearly enough, because I could not find any proper cannabis soil.
Now I have good soil, and supersoil. But it sounds like it would be better with biochar!
And that's all I do. I mix it 50/50 with fresh worm castings and let it sit in a covered bucket until I need it. It does need some time to infuse though as straight char in your mix will act as a sponge or filter and suck up the nutrients you are trying to feed you plants and leaving deficiencies in the near term. But, if you let it sit a while before you use it, it becomes a source of nutrients and moisture for your plants.
Ok, cool.
How long is, "a while"?
I don't see where that would be much different. Just pile a bunch of leaves and fronds in a pile at least a meter deep and wide, moisten it like a compost pile and let it sit for a couple of years. That should give you the same basic stuff I'm working with.
Ok. We are hopeful to have our paperwork done soon, and are already looking at properties.
Once we find a place, we should have room for experiments, organics, compost, etc.
I was told that what they do here is to dig a big hole (however big you think your root ball will be), and then just throw your kitchen waste into it (with lots of egg shells and bananas, and maybe some rice hulls, which are dirt cheap here), and then let the worms at it.
Then I guess they normally plant a big start here at the start of summer (normally June), and let it run until fall.
They say that both Maria and Juana love it, so of course we will have to give it a try!
So that will be an in-ground greenhouse, which will be different still.
I had an in-ground greenhouse in northern California one time. There I had a bird mesh permanently installed, and then I took the plastic off for summer.
Here I will probably just put big passive vents I can open during the day.
I am looking forward to learning about your Korean fermented soils! I just need to focus on my basics for right now, and then when we move, I hope to try things the Korean way!
I love Kimchi, and sauerkraut, and am generally a pushover for fermented anything.
I am eager to try some Malawi fermented cannabis!
But I will also probably have to learn how to properly cure, first, haha.
You can mix them into the soil if there is anything left, but they should dissolve over time into your mix. The 20% you mix into your soil should leave voids in the soil as it dissolves leaving space for the growing roots to inhabit.
Ok, cool.
So, not like a teabag (that gets spent), but like a hard pellet of worm poo, that washes a way a bit at a time?
Please correct me if I am wrong, but in that case, I will treat it the same as new (and measure it by weight).
