Anyone ever used this from the coal refinery's as fertilizer? I was looking for some input due to it being cheap here close to me
I'd be concerned about excessive sulfur and possibly molybdenum levels adversely affecting copper uptake by plants...and subsequently exacerbating possible copper deficiency in animals grazing that ground.
Seems like I recall Dr. Bob Van Saun, from U.Penn. providing a case report of a trainwreck involving a father/daughter sheep operation, where the father was using regular ag lime, but the daughter had purchased and spread some cheap refining/mining byproduct sold as a 'liming agent'... that caused a tremendous loss of lambs and ewes... while those on Dad's place, next door, were just fine.
