The core
Seedmeal 4 pts
Lime .75 pts
(NPK C,Ca)
...
...better
Agricultural lime .25 pts
Dolomite lime .25
Gypsum .25
(mix lime up from these three kinds)
(adds Mg,S, and better ratio to Ca)
...
... even better
Kelp meal ~1 pt
Rock phosphate 1 pt
(adds Trace minerals and other catalysts, and better P ratio)
*From Steve's book Gardening when it counts, starting pg21
There are some notes/alternates:
- Something called coprameal [from coconut oil] for a low potency mix [less NPK, presumably]
- Blood and bone [tankage] for 1pt of the seedmeal [high NPK]
- Dolomite is usually the better lime if you can only afford one
- Ag' lime if you can afford two
- Gypsum least necessary
- rock dust {azomite?} for kelpmeal
- bone meal or bat guano for rock phosphate
- Finely ground as possible
