Items I have at the ready
oak leaves——— 0.80 - 0.35 - 0.20
comfrey———— 1.80 - 0.50 - 5.30
goat manure—— 1.35 - 1.00 - 3.00
Chick manure-— 5.00 - 2.00 - 1.00
bone meal——— 2.00 - 11.0 - 0.00
Wood Ash——— 0.00 - 3.00 - 16.0 and raises pH
Manures are as dried manure.
Biochar is not listed and I didn’t find it elsewhere aside from mention that it does raise K and Ph levels.
I thought comfrey was all N and was surprised to see the K three times the amount of N. No mention of dried, fresh or tea. I’ll have to look around for more info on it. Mine might be big enough to clip some leaves this Fall.
I made more potting mix yesterday by using the other I had made but adding leaf mold and just a little soil. By Fall, I plan to have a mix or some mixes figured out using what I have here plus some sand I’ll need to buy. I’ll just get a yard of it which ought to last a long time since the mixes can be reused. I need some for raised carrot beds too.
They don’t have “biochar” by that name, but it does have “corncobs ground charred” which is one type of biochar. Apparently that’s a 0-0-2.01
Looks like a fun site to poke around in.
