Inputs - Section 6

Water Soluble Calcium Phosphate (WCP)

The Water-soluble Calcium Phosphate (WS-CaPo) is extracted from the bone of vertebrate animals. WS-CaPo is an essential substance for plant growth and is widely distributed in the soil.

Calcium phosphate is insoluble in water, but soluble in acids: this property is used in Natural Farming. Calcium phosphate can dissolve slightly in the water containing CO2.

WCP is great for building strength and for using during times of pregnancy.




Video by OneDrive, he speaks on WCA and WCAP.  

He has so much information I recommend watching it if you have not.



Video By Chris Trump and illustrates the bones very well.

Instructions for WCP

Ingredients Needed

  • Animal bones 200 gms (Cow / Pig / Chicken/ fish)
  • Brown Rice Vinegar 1 liter. (BRV)
  • Clay Jar / Glass Jar
  • Porous paper ( Paper towel)
  • Rubber Band


  1. Ready the bones and remove all bits of food and leave only bone.  (Pig, chicken and fish bones are common)
    1. Boil the bones and let dry in sunlight.
  2. Break the bone/shells into small pieces 
  3. Lightly roast or grill the bone in a frying pan or foil container over low heat for approximately 45 minutes to remove any organic substances that will rot and contaminate the WCP.
  4. Bones should be dry burned black all the way through but not ashed or tanned from being under done.  Should almost look like charcoal.
    1. Shells do not need cooked.
  5. Add the charred bone to a glass jar filled 2/3 full with brown rice vinegar, a store bought fermented vinegar will work just as well at a 1:10 ratio by weight.
    1. Vinegar should not be distilled.
  6. The vinegar and material will make carbon dioxide bubbles, while the calcium is being dissolved into the solution.
  7. Cover the mouth of the jar with breathable cloth, such as muslin, or paper (not plastic) and secure with rubber bands or ties to keep out pests.
  8. Place the jar out of sunlight and bright lights for 7 to 10 days.
    1. Letting it sit longer than needed will not hurt the WCAP.
  9. After this time, check if bubbles are present in the solution.
    1. If bubbles are not present, the WCP is “saturated” – proceed to step 10.
    2. If bubbles are present, add more roasted bones or shells and let stand for 1 to 2 more days.
    3. Repeat until the solution stops producing bubbles.
  10. Strain the vinegar-and-bone solution through a colander into a clean glass jar to remove eggshells.
  11. Label the WCP solution and store at room temperature out of direct sunlight.
  12. compost the remaining materials.

Applying and when to use WCP

  • Apply WCP during the Change-over period.  
    • It promotes the differentiation of flower buds resulting in high fertility and yield.
  • WCP improves the sugar content of fruits.
  • Apply WCP when the colors of leaves turn light or dark green.
  • WCP can easily travel within the plant and move to the vigorous new leaves first. As a result, symptoms of deficiency appear mainly on the petiole and veins of the old leaf.
  • The new leaf does not grow well and it becomes smaller and dark green in color.
  • The growth of flowers is noticeably suppressed, naturally bearing fewer fruits.
  • The fruit skin becomes thick and the acid content increases.
  • Dilution rate of 1:500
    • During transition stage.
    • Using with pregnant animals.
  • Dilution rate of 1:1000 when mixing with water soluble calcium inputs.


Congratulations for learning about WCP
