I was planning on using crushed oyster shell powder for my next organic grow. I didn't realize that oyster shell powder means ancient deposits of oyster shells that are mined and then turn into a powder, I thought it just means regular oyster shells crushed to a powder. Now I have 10kg of homemade oyster shell powder from regular oyster shells but apparently, they take so long to break down that it's not really useful. Does anyone have any input on this or even better, experience with it? I can't buy the proper oyster shell powder because it's not available in my country and too expensive to import.

Your oyster shell powder will be fine, though its best to let them bake in the full sun for a couple of days to kill bacteria.

I make my own bone meal from beef and chicken bones. I roast them first. The chicken bones grind easy but some of the beef can be stubborn and I end up with chunks I just throw in the garden. I grind eggshells as well. I don't throw anything away that can be used as a soil amendment or plant food. It's not that I can't afford to just buy bone meal but I ate the animal that gave its life for my meal. I'm not going to waste any part of the animal that can be used by tossing it in the trash.
