Not all gypsum is the same

With all the success farmers have had with SuperCal SO4, it’s no surprise there are many products emerging that claim to be as good. Many of these products are not true dihydrate gypsum or have impurities and heavy metals, and really don’t work like SuperCal SO4.  

One of these products has a long list of application guidelines. Check it out:  

best applied with a fertilizer or litter spreader, ideally equipped with a stainless steel box with steep sides (45°angles) and a wide belt. In absence of a stainless steel box, graphite film coating or plastic liners can be used to assure the gypsum slides easily onto the belt.  It is recommended that non-essential interior gates, partitions and braces be removed.  Twin spinners are important to ensure a wide, uniform spread pattern. can bridge … feather on bed rather than dumping it all in center. Try to avoid piling against rear gate."  

Hmmm, sounds like a lot of hassle.
