Water-soluble Calcium Phosphate (WCaP)
What is WCaP?
Water-soluble Calcium Phosphate (WCaP) a liquid fertilizer. It is made from animal bones and vinegar. It is calcium phosphate saturated solution with vinegar. Phosphoric acid and calcium were thought to take effect slowly. However if you improve the production method and use it according to the plants' life cycle, it can have a fast effect.
How to make WCaP
Prepare animal bones (cows, pigs, chickens, etc.)
Boil and burn the bones to remove the fat and meat.
Put the bones in a container filled with brown rice vinegar (1:10). The bones will emit bubbles. When the bubbles stop, add more bones. If it bubbles, it is not saturated. If it does not bubble, the solution is ready.
