I shouldn't have opened that can of worms, lol. I can't really explain it much except to say that it provides the needed nutrients at a peak when the flowers just come in. I think the Dolomite Lime doesn't break down fast enough to allow the plant the magnesium it needs to uptake the calcium. I think that is how it goes, but don't quote me because I am not so positive. I just know it is what I have learned about growing tomatoes in a SWB.
Check your local nursery's because it's used in lawn care I think. You are looking for CANo3.
