Greensand is an oceanic deposit of mineral, primarily potassium, but a lot
of minor, trace elements too. I think they mine it in New Jersey or
Delaware, someplace like that. Probably an antediluvian deposit. BTW, I
love alfalfa meal. Has lots of good stuff in it, including a growth
accelerant of some sort. I use 50% processed steer manure and 50% alfalfa
meal in my veggie garden, and plants do love it. Margaret L
