Water Soluble Calcium Phosphate
Learn how to make water-soluble calcium phosphate that is easily added to plant and animal nutrition and hydroponics
Materials
- Clean animal bones - mammal bones preferable
- Brown rice vinegar or other fermented vinegar -- never distilled
- Grill or fire pit
Instructions
- Place your bones on the glowing coals or fire -- either directly or on grate. They will catch fire, so make sure to have adequate space around the area.
- Rotate to make sure they blacken on all sides.
- They are done when they are hollow.
- Put one part of crushed (not powdered) charred bones to 10 parts brown rice vinegar into a clean, half gallon-sized mason jar, but only fill 2/3. No brown or unblackened bones.
- Cover with paper towel tied with string. It will be bubbly and active at first like soda. After about a week or so, when it stops moving, you can strain off the vinegar into a bottle for storage.
- Label bottle with name of contents (WCP) along with the date and dilution rate of 1:1000
Notes
What does the dilution ratio mean?
A rate of 1:1000 means for every liter (1000 ml) of water you only need 1 ml of WCP. Since one teaspoon is roughly 5 ml, that means for every gallon of water, you would add just shy of a teaspoon of WCP. One gallon of water feeds a 100 sq ft bed. A little goes a long way. More is NOT better.
Note that when I say 'feed' I mean we're feeding the soil. We're building up the resilience and balancing nutrients within the soil. KNF always focuses on soil first, mainly because the mouth of the plant is in the roots. This means that not only will your current crops benefit, but the next year's crop yields will be higher too!
