Gypsum as a Sulfur Source?
I read about using gypsum as a sulfur source in No-Till Farmer. This may or may not be a good idea. If you need calcium to offset the effects of excessive magnesium, it is a great idea. If you already have excessive calcium, you could contribute to low magnesium issues. Know what is going on with your soil before applying any amendment.
