Does anyone use this to break up high clay soils? I know adding lime to a high PH soil isn't supposed to be done, but I've heard a few people say it really helps break up the soil and doesn't raise the PH anymore than it already is. Do Cal-Sol gypsum type products do this quicker than calcitic lime? I know that compost will do a better job, but it is hard to find a supplier in my area, plus i don't have the equipment to put it down at a reasonable price. So I'm looking for an easier to spread alternative that will bust up this clay. Soils are high in PH, low in K, high in mag, average in calcium if this helps.
