Water Soluble Calcium Phosphate in Natural Farming Practice
Water soluble calcium phosphate (WCP) is a valuable natural resource that can be easily made using grass-fed beef bones and organic fermented vinegar. To create WCP, the bones are first roasted to ensure they are clean and free of impurities. Then, they are carefully broken into small pieces and combined with the vinegar in a specific ratio.
After mixing, the bone and vinegar mixture should be allowed to sit undisturbed in a shaded area for several days. During this time, the bones will gradually dissolve, and the liquid will begin to separate from any solids. Once the bones are no longer moving or forming bubbles, the liquid can be considered water soluble calcium phosphate.
The next step is to strain the liquid to remove any remaining bone fragments. This can be done using a fine mesh strainer or cheesecloth. The resulting clear liquid should then be stored in a clean bottle or container. It is now ready to be used as a natural farming practice amendment.
Water soluble calcium phosphate can be applied to the roots and leaves of plants during different growth stages. This application helps strengthen the structure of plants, making them more resilient to infestations and diseases. Additionally, WCP can also be given to animals as a supplement to support their skeletal development.
