Has anyone made bone meal?
I am making a big pot of beef bone broth right now and I would like to try to make bone meal with the leftover bones. I have looked in old books and on the internet for years, but I've only found one reference. A reprint of an old book said that burying bones in ashes would turn them to bone meal. I have left them buried for well over a year and as far as I can tell, they are unchanged. Any ideas?
