Biochar is a classic “inert” ingredient; it creates an environment that enhances chemical processes essential for biology, especially digestion. Biochar also changes the properties of dung, making it lighter, drier, easier to handle. This eliminates toxic trouble at its source, to further improve health. And since dung has digested biochar, this improves other properties of the dung. Biochar is also a catalyst to facilitate populations of microbes. Many bacteria, fungi and other simple life forms prefer biochar as habitat, and take up residence in its micropores. Biochar can increase nutrient adsorption, retention and transport to improve the liver-intestine circuit.
