Water-Soluble Calcium Phosphate (WCP) — Soil Amendment Recipe
WCP solubilizes phosphate from properly burned bones using BRV, supporting flowering, root flush, and seed maturity. It complements WCA as peppers transition from vegetative mass into reproductive allocation.
WCP solubilizes phosphate from properly burned bones using BRV, supporting flowering, root flush, and seed maturity. It complements WCA as peppers transition from vegetative mass into reproductive allocation. This Soil Amendment preparation is made with vertebrate bones (fish, poultry, livestock) and is a staple input in regenerative Korean Natural Farming — feeding soil biology instead of relying on synthetic fertilizers. It is one of 50+ free recipes we use daily at the IC SPICY nursery in Port Charlotte, Florida.
Ingredients
- Enough to fill jar 1/3 Vertebrate bones (fish, poultry, livestock)
- cover bones + 1 inch Brown rice vinegar
- 1 Heat-safe crucible / outdoor burner
Steps
- Low-temperature burn bones until brittle, chalk-white-gray—not charcoal.
- Cool; crack bones; pack loosely in glass or ceramic—not metal with long soaks.
- Cover with BRV; vent CO₂ if foaming.
- Soak 7–10 days; top vinegar if evaporation exposes bone.
- Strain liquid WCP; store labeled; solids may re-soak weaker.
Common questions
How long does Water-Soluble Calcium Phosphate (WCP) take to make?
Plan for about ~10 days from start to finish. Fermented and cultured inputs improve with proper timing, so follow the step schedule in the recipe rather than rushing stages.
When should I apply a Soil Amendment input like this?
Match the input to the plant's growth stage, per Master Cho's nutritive cycle theory: vegetative-stage plants favor growth inputs like FPJ and FAA, while flowering and fruiting plants favor WCA and FFJ. Apply early morning or late evening, and never in strong midday sun.
Is this safe for organic or no-spray gardens?
Yes — like all IC SPICY CookBook recipes, this uses only biological and food-grade ingredients with zero synthetic fertilizers or pesticides. Always label your jars, use clean tools, and do a small test application before treating every plant.
