Over the past few weeks, people have asked is what is SuperCal SO4?
SuperCal SO4 is pelletized gypsum, however we put in a crazy amount of extra time and effort to ensure our products are highly effective. We call it the SuperCal Advantage and it consists of three components
Purity Particle Size Precision
SuperCal SO4 is a true dihydrate gypsum mined from one of the purest sources of gypsum on earth. Many people think, gypsum is gypsum, however science shows us this is just not so. Check out this test from Pace Turf .
We’ve also spent extra time and effort to test many sources of gypsum, and none compare to SuperCal.
Particle Size Matters
When it comes to mined gypsum, none are ground finer prior to pellitization than SuperCal. The combination of purity and particle size results in the highest dissolution rates in the industry.
Why I am telling you this?
Gypsum is a rock, and if you cannot get it to dissolve in the soil solution it won’t work. Gypsum, limestone and fertilizer all must dissolve in the soil solution to be effective! Large particles don’t react in enough time for you to see benefit from it.
We Pelletize for Precision
The reason we pelletize is to ensure our very pure, finely ground SuperCal SO4 spreads evenly for maximum effectiveness. With nearly 30 years in the industry, we have perfected a formulation resulting in low dust and precise spreading on every acre. Poorly applied product costs the grower yield.
A study from Virginia Tech confirms what the farmer knows, “The results of this research proved conclusively that non–uniform application of fertilizers resulted in less total yield than uniformly applied fertilizers even though the same total rate per acre had been applied in each case. The loss in yield due to lower than recommended rates of application far exceeded the slight increase in yield obtained from excess application over the recommended rate.”
Whether its wet or dry, bulk gypsum won’t spread well.
The other issue with finely ground gypsum is drift loss. The chart below was developed from a USDA program that was developed to predict the motion of spray material released from various devices connected to an aircraft. Values and assumptions were modified to match that of a dry material in a rotary spreader in an agricultural setting.
Based on this work, you could see up to 25% or more drift from a bulk applied product. The finer and dryer a product, the farther and greater the drift!
Only SuperCal SO4 ensures you the highest quality, most effective product in the market, backed by over 20 years of success and farms all across North America.
Here is one mutli-year study by Iowa State. Wider yield differences were experienced early in the study due to application on known sulfur deficient soils. Regardless, the consistent yield improvements speak for themselves.
For farmers that demand consistent repeatable responses from their inputs, SuperCal SO4 is the only market proven product. If you still have questions, give anyone of our staff a call!
