Art, you are speaking of CEC, as well as bacterial and fungal interactions. These things are very important for healthy growth of plants, without a doubt.

Looking over your links, they refer to "holographic data transfer" that allows bodies of water to become healthy by "reminding" them of their healthy state.

Could you explain how the two are related?
