Hello Permies World!
I'm going to start building my own thermal compost following Ingham, Lawton, etc. I have horse manure nearby, and will be using it, but I also have been offered both yeast and grain waste from a small brewer. I have found research that supports adding the waste grain, but nothing about yeast. I know brewers yeast, a fungus, make alcohol, which I presume would kill other microorganisms. If the yeast are dead, is it safe as a source of N? Is it even high in N? I don't want to add it in until I know its value other than as animal feed and what it could do to compost. Thanks in advance
