Like Ben Franklin did in Philadelphia over 200 years ago, our farm at Martinsville has been plastered. I have been advocating gypsum for over 20 years now and it is finally available from a local fertilizer dealer. He was looking for a way to justify the cost of a new spreader he bought and the details were worked out and now he is applying gypsum all over the county. I know he spread over 1000 acres in the past two weeks.
He spread gypsum for a local farmer this spring who said one application took all of the variation out of his yield monitor at harvest. Yield maps are usually colored like children's artwork so just making that map pretty much one color proves why we are doing it.
Gypsum varies in properties and is much misunderstood. It is not a miracle potion for soil and crops but by reading my enthusiasm for it the past 20 years, you might think so. Gypsum is around 21% calcium and 16% sulfur. If it's made from fly ash, it probably contains more electrolytes. It should not poison your ground like so many naysayers first reported and still do today. Find the truth for your farm.
I first reported my findings at the National NoTillage Conference 14 years ago. I told the audience the best way for me to explain the value of gypsum to me as a no-till farmer is I had no standing water on my fields after one application. That means I had more oxygen in my soil and that did result in better crops. I was asked questions so long after the presentation I couldn't talk anymore.
I am getting those same questions today, I just answered 3 of them. Word travels slow if it is hard to do or understand and gypsum is just that. It's a great soil amendment and can help you reach your goal of better soybeans and crops in general. This has been true on my farm and many of the Midwest soils I work with.
