There are allot of ways to skin a cat. I do it as cheaply as possible. As long As it's fluffy, drains well but holds water, isn't hydrophobic, has enough nutrients in the right balance, and is verry alive and breaking down quickly, it works. It has to stay that way over the years. I treat my soil like compost piles. Whatever i throw in there decomposes fast and i keep introducing fresh organic material to keep it that way.
For the base media 1/3 compost, 1/3 drainage material, 1/3 fluff.
The drainage material i do a mixture of lava rock and perlite. Mostly lava because lt lasts longer and doesn't float as easy. For the fluff i usually do mostly coco. Pine bark fines or peat is good to add fluff of you need to bring ph down.
Lots and lots of organic nitrogen and fresh organic material.
An easy one is (per yard)
37lbs of chicken manure pellets
2 lb of calphos
7.5 of fishbone
1.5 of langbineit(or potash depending on your water source
7.5 lbs of alfalfa
You can substitute Lots of things but the alfalfa isn't optional. It gets your mix cooking. It brings the soil alive and decomposes fast. You stick your hand in it when you first add allot of it and It's unbearably hot. If you have time to let out break down, put as much as you can in.
