I got some soil additive from my cousin the she called human or humane or something like that. She said the only two places it is mined in the world is Cuba and Israel. it is black and looks like shell that has been grinded. It is added to soil in very small amounts and will help plants. I googled it, but I couldn‘t find it anywhere. Can anyone tell me what it does to help plants or how to find it on the web??
I was going to sugget it was humanure (fertilizer made from human waste), but then you said it was mined. Not sure what your mined fertilzer/soil additive is - I think the simplest way to find out is to call your cousin and ask her.
could it be bat droppings they mine that
