Case study: agriculture
I have worked in collaboration with maison Callegari for several years to my complete satisfaction, thanks both to the quality of their merchandise and to their customer service. Their Carbo-3 charcoal has let me avoid the use of copper as a steep water anti-rot agent in my hot rooms. Also, there are lots of possibilities to use semi-activated Carbo-3 charcoal, and its fungicide and liquid retaining qualities, not to mention its ability to change structure when mixed with a growing substrate, are very promising.
