Gypsum: Source, purity, and particle size matter

The goal of putting a product on your turf is to realize the benefits of that application as soon as possible. Paying for a product that may take years to work just doesn’t make sense. People may argue that gypsum is gypsum, but in reality that’s not true. There are multiple forms of gypsum: calcium sulfate dihydrate (true gypsum), calcium sulfate hemihydrate (bassanite), calcium sufate anhydrite (anhydrite gypsum), and synthetic gypsum, which is a by-product of scrubbers at coal-fired power plants that force sulfur exhaust gas to combine with calcium carbonate (limestone) to form synthetic gypsum. Within most products on the market that are true gypsum, there can be differences in the purity and particle size distribution, which matters when it comes to getting the most effective product for your turf. Dissolution of a gypsum product into the soil/water matrix is an extremely important indicator of how the product will…

Is it SuperCal 98G or SuperCal SO4?

SuperCal 98G and SuperCal SO4 can often be confused. From their similar names to the similar nature of their appearance, people wonder, how do I know which product I have? The vinegar test is a simple test you can perform quickly and easily to know whether the product you have is SuperCal 98G or SuperCal SO4. The acid neutralizing reactions between the carbonate and acid in the vinegar will cause SuperCal 98G to fizz. Since there is no carbonate in SuperCal SO4, it will do nothing. Combine no more than 1 teaspoon of pellets and a 1/4 teaspoon of vinegar in a reaction proof container with an open top.    SuperCal 98G is on the left, with its tell-tale fizzing. That is a result of 1 ml of vinegar and 1 tsp of each product. SuperCal SO4 is on the right, no reactions.    

Gypsum is gypsum . . . right? Wrong.

  Gypsum is gypsum…right? Wrong. Gypsum is just gypsum and any will do, right? Wrong! Just like any product in the marketplace, there are high quality and low quality gypsum's and the adage of you get what you pay for is absolutely true. Gypsum is a very misunderstood amendment; most people don’t understand the value. Before I talk about how the quality of gypsum can affect its effectiveness, let me give you a general overview of the material. Gypsum comes in two different forms, both of which can be used in the turf industry. The first is calcium sulfate anhydrite and the second is calcium sulfate dihydrate. As you can read, both forms have both calcium and sulfur as part of the elemental make-up. The difference between the two, however, is directly tied to its effectiveness and that difference is water! The second form, calcium sulfate dehydrate, has 2 additional…
