ah, well greensand is great to use, it's reaaaally slow, and probably useless the first season, the potassium availability is akin to like granite dust, verrry slow..i'm getting ready to mix soil for six new planters.im going off of coots mix.using goat compost and happy frog for the base.found a friend who has a bunch of comfrey im going to transplant(yes,its the invasive kind,lol) how much greensand per cf @greasemonkeymann ? any other tips on additional amendments that arent on coots mix?
it does work well for aeration, and believe it or not it does absorb water too, so as a soil input it's good for that reason.
slow release is good for many reasons but perhaps the most important is that it's extremely forgiveable, so if you add too much, it's not like BAM and it's toxic...
one of the reasons I don't like soluble nutrients..
anyways, so greensand is great to use, but remember that goat manure and comfrey are already high in potassium, and the amount of manure typically added to a soil is more than the amount of nutrients added, meaning even though the NPK numbers of manure is modest, it's used in larger overall % of the soil makeup, make sense?
sorta why I tell growers to not concentrate on the nutrient values sometimes, sure it's good to be cognizant of them, but not to overthink it all.
I don't remember exactly what is in the coots mix, but I remember it being pretty comprehensive, let me look a lil..
is it this one?
I copied it

BAS has his mineral mix listed as this:
1 Part Brix Blend Basalt - Trace Minerals and High Paramagnetic Energy
1 Part Gypsum - Locally Mined in Colorado - Calcium and Sulfur
1 Part Oyster Flour - Mined from San Francisco Bay - High in Calcium
1 Part Glacial Rock Dust - Gaia Green Glacial Rock Dust - Trace Minerals
(1 Large Mineral Kit will mix with 1/2 Yard of soil) 1/2 Yard is = 13.5 Cubic Feet
Use at 4 Cups Per Cubic Foot
But I saw coots in 2011 post 5 parts glacial, 1 part basalt, bentonite and oyster in the ROLS thread.
Then I found xmobtx on another forum in 2014:

RECIPE Now, for a tablespoon per gallon, 1/2 cup per cubic foot is "close enough" ~so you can adjust to make smaller batches!
mix your neem, crab & kelp meals {if you want alfalfa meal it goes in here too} ~apply this mixture @ 1 cup per cubic foot
mix your glacier dust, basalt dust & if you want it clay/azomite ~apply this mixture @ 2 cups per cubic foot
gypsum & oyster flour mixed @ 2 oyster to 1 gypsum is applied @ 2 cups per cubic foot
if you want it, put your biochar in @ 1/2 cup per cubic foot
--------------------
I like the inputs, except the gypsum, with those others the calcium in the gypsum is a bit much, you'll have it elsewhere. (don't get me wrong, gypsum is GREAT, but often not needed)
but like nearly every other input in there is good with calcium
I do like the sulfur though, but you have that in the neem meal too, and smaller amounts in the goat manure too
I also like the smaller amounts he recommends too
one thing I can say though, be CAREFUL amending a manure based soil mix, too often the manure alone is plenty to go with.
I messed up two different mixes doing that
a rabbit manure mix and an alpaca based one
both of those are good to use almost bare.
(alpaca OWNS in the manure world btw)
I can be more specific if you give me more information, the amount of manure added
any d-lime or just the oyster flour to control the ph?
