I think what the gentleman in the video is doing is a amazeing mix of natural phenomenoms, science and benefit.
The idea of feeding charcoal to cows occured to me a while back too, but didnt find enough courage to try it. Wuldnt like to hurt any animals but seeing this video l will definitly reconsider.
The idea occured to me while watching one of Garry Gilmores videos, when he mentioned he puts charcoal in the pony stable so that they work it in the dung and make good fertiliser.
I allso saw a video of growing plants directly in sun dryed rehidrated cow dung. Now, that seemd to work great for them. If there were charcoal in it too, shuld be eaven better.
Charcoal and soot was long being a remidy for cattle here, in cases of diharea. But l was wondering what a long term char diet wuld do, this video shows some great promise.
We do not pasture our cows (yet) and our pastures are quite fertile, but it is the charcoal compost fertiliser l aminterasted in. First, for our gardens/fealds, and second, biochar stuff sells for crazy money here. A pound of inoculated biochar cost 27$ last year at a local gardening center.
As for human consumption, l watched a video of a guy teaching people how to make biochar. He sayd, in order to determin the product is 100% biochar, thebest method is to chew a peace. It shuld taste like nothing.
I dubt it wuld do any harm to a human body in small cmquantitys.
