Let There Be Lime

In January 2015 featured an article written by John Deitz, Let There Be Lime. The focus of the article is the how SuperCal products are helping producers in in Western Canada reclaim land and increase yields

Key Points from the Article:

  •  “If we can apply lime annually to a very small width of application within actual areas that need to be treated, we can drive annualized costs down to between 7% and 9% or lower than the amount the old methods would use,” Solberg says.
  • In 2013, ENR applied a 600-pound rate of SuperCal SO4 to about 200 acres of white, hard, grow-nothing land in southern Alberta that had 26% sodium. It harvested 80-bushel barley on the treated area.
  • The 400-pound applications of SuperCal 98G increased soil pH by about 0.6 and offered the best return – nearly 9 bushels per acre. Cost for the product and application was about $57 an acre.

What is SuperCal SO4?

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.

Applying SuperCal Products on Snow Covered Ground


We are often asked about making application of our products on snow-covered ground. Applications in the late fall and early winter should have the same types of considerations as they do in other parts of the year.

When considering application timing, water should always be the preeminent issue. Water influences the movement of soil applied inputs, and when water has potential to run (and not infiltrate), then perhaps applications should be delayed. These events are not always easy to predict, so using your best judgment is the way to go.

Poor Wheat Tillering Due to Aluminum Toxicity


We thought you should be aware of a good article released by the Plant Management Network, originally written by K-State, entitled Poor Wheat Tillering, Root Development May be Due to Aluminum Toxicity.

From the Artilce:

“…the producer should make a note of this condition (low pH/Aluminum Toxicity) and take action before planting another crop on that field. Lime application on low-pH soil should be considered a high priority. Even half-rates of lime will do some good,”  Dr. Diaz said.

“Aluminum toxicity begins to occur where soil pH levels are less than 5.0 and potassium chloride-extractable free aluminum levels are greater than 25 parts per million, Ruiz Diaz said. Some varieties of wheat, such as Everest and Overley, have better tolerance to low-pH soils and high aluminum levels than other varieties, such as Fuller. The symptoms of aluminum toxicity include poor tillering and sometimes, but not always, a purplish color, he said. “In addition, older leaves may appear drought stressed and withered. Plants will either be stunted throughout the season even with adequate moisture and nitrogen, or may even die,” he said. High concentrations of aluminum will reduce development of the roots, giving them a short stubby appearance. “The roots will often have a brownish color, and the root tips may have a burned appearance. This effect on roots will limit nutrient uptake, and plants may show some deficiency symptoms even with good nutrient levels,” Ruiz Diaz said. In addition, low soil pH (below 5.0) can reduce the availability of plant nutrients such as calcium, magnesium, phosphorus, and potassium.”


We couldn’t agree more, the following pictures is what happens to the roots when aluminum toxicity is a problem.

Need More Proof SuperCal Works


One of the comments we get a lot is, what data do you have to support your product works? We have many trials that back our claims, yet many agronomists and farmers need more proof. Sales of SuperCal 98G and SuperCal SO4 have grown stedily every year since we started. The growth in our sales in from farmers trying the product and seeing it works for themselves.

What about the people that need more proof?

Seth Godin says it best in his blog;

Too much data leads to not enough belief

Business plans with too much detail, books with too much proof, politicians with too much granularity... it seems as though more data is a good thing, because data proves the case.

In my experience, data crowds out faith. And without faith, it's hard to believe in the data enough to make a leap. Big mergers, big VC investments, big political movements, large congregations... they don't usually turn out for a spreadsheet.

The problem is this: no spreadsheet, no bibliography and no list of resources is sufficient proof to someone who chooses not to believe. The skeptic will always find a reason, even if it's one the rest of us don't think is a good one. Relying too much on proof distracts you from the real mission--which is emotional connection.

So why don't we have reams of data? Because if you've tried our products you know they work! Makes you wonder why some products work so hard to "prove" they work?!?

Greetings from Redwood Falls

The first day of Farm Fest is under our belts. It was an interesting day. We meet a dowser, a writer for a magazine, a couple of politicians, and lots of farmers and agronomist. If you are planning on coming up to the show we are in the big yellow tent, it's between the red and blue tents.

We heard lots of good stories today, and had lots of questions asked. One in particular caught me off guard.

Reporter: "If your selling lime and gypsum, why does you booth show a cafe scene?"

Me: "It got you to stop and ask me about it didn't it, actually it is part of a marketing campaign."

What are you doing to get your customers to take time to stop and talk with you?
Having poor turnouts for your customer meetings? Have you changed the format and topics lately?

Does the cost of fertilizer have you thinking about not talking about it anytime soon? If you're thinking about it, your customers are. Why not include that in fall tour discussions. It may be a good time to add that fixing pH will make their fertilizer work better.

Having you customers ask you about SuperCal latter is a lot easier than "trying" to tell them what it will do for them today.

The old adage, you can lead a horse to water, but you can't make him drink, holds true. Don't show them the water, tell them how clear, cooling, and refreshing it is. You're thirsty now aren't you. It is strange but it works. Don't tell your customers the whole story, even if they ask. Most people cannot place themselves in the story. Give them a few details, and let them make their own story, it's better than yours anyway.

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.
