Does anyone know where I can get rock phosphate? I've checked a few places close to home, but all I can find so far is bonemeal. I hate having to drive all over the place looking. Thanks in advance.
What is it, and what do you use it for?
Rock Phosphate is a mined source of phosphorous(and calcium), as opposed to bonemeal which can attract animals to the garden. I believe it is skeletal remains of prehistoric animals. Phosphorous is the middle number in fertilizers, ie, N-"P"-K. I'm looking for it because I don't want neighborhood dogs digging up my tomatoes looking for "bones". :)
