michigan		Sready, you are right. This thread is of great interest. I have a farm that is downwind of a cement plant. It has since closed and they have dismantled the plant but are still activly mining for gravel. It had started operation in about 1960 and ceased operation about two or three years ago. So the question is how to best deal with a ph of 8.1. Local agronimist had us spreading k-mag. Soil testing done three years later (different lab) had it looking like we were depleting the potash levels. Long story short, I have decided that it is tough to undo 50 years of high calcium, high magnesium fallout from a cement plant smokestack in a few short years. Continued soil testing and course corrections will get us there. I am tempted to go to continous corn just so I can use NH3 (gasp) every year. Until then I try to glean information from these threads on how to best deal with this.
