Can 98G and SO4 be Applied on Frozen Ground?

Frozen Ground

We are often asked about applying our products on snow-covered or frozen ground. While it may seem intuitive that products should not be applied to frozen ground, in general, applications can be made during late fall or winter and have similar considerations as other times of the year, such as water and ground conditions.

When determining if conditions are adequate to apply SO4 and 98G, keep these considerations in mind.

Potential for water runoff

Water influences movement of surface applied inputs. When water has potential to runoff and not infiltrate, then perhaps applications should be delayed.

Late fall and early winter before the ground is completely frozen can be a good time to make applications. As long as there’s not a substantial amount of snow on the ground (less than 6 inches), applications of 98G and SO4 can still be made. If snow comes early, there’s potential that it will slowly melt and start breaking down the product, which will help disperse the particles of the pellets and make them more effective come spring.

Even if the ground is completely frozen, applications can be made before too much snow accumulates. An extremely wet spring with multiple, heavy rain events can lead to water, and thus, product runoff and off-target effects, so paying attention to long range forecasting can help inform application decisions.

Slow snow melt and ground thaw is the best case scenario for products applied on frozen ground. Even if there is some runoff, it’s not likely that all of the product will be taken from where it was applied.

Soil tillage

Heavy or primary tillage (moldboard or chisel plow, ripper) is not a recommended practice after application of 98G or SO4. Application should be delayed until after these tillage practices have already occurred, due to non-uniform depth of application and the likelihood that the pellets will be placed too deep in the soil profile to affect meaningful pH adjustment.

If ground is not completely frozen, then there’s still a chance for the product to start working its way into the ground. SO4 should always be surface applied and left to release its nutrients from the surface, so if some tillage is expected after the application, it may be wise to delay application until spring after ground work has been completed. 98G can be incorporated via surface preparation, so the same considerations do not apply to both products in this case – incorporation can also reduce runoff potential for 98G.

Field slope

Slope of the field should also be considered; relatively flat ground is less susceptible to runoff events and will have more leeway with late fall and winter applications.

To summarize, frozen ground applications are acceptable if snowpack and slope are minimal – however, the risk of excess water in the spring and significant runoff are always present.

Let There Be Lime

In January 2015 Agriculture.com 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 

Purity

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!

Any soil amendment will do….

 

Many growers think all soil amendments are created equally. The demanding grower knows better, as the demanding Tequila drinker knows that not all Tequila is created equal.

Check out this fun video Not Just any Tequila from Hornitos Tequila

Choosing any soil amendment product is worse than asking for any haircut. Hair grows back, yields don’t!

Protect your high yielding crops by asking for SuperCal!

Fly-In Plant Tour

Calcium Products was pleased this week to host one of our dealers.  Harold Hartzler, and his family, visited our plant at Fort Dodge.  Harold has been a dealer for many years, but has decided to start reducing the pace of his activities, and turn over many of the business responsibilities to his grandsons.

Since Harold and his family live in Ohio, they elected to fly to Fort Dodge.  After staying overnight, the group toured the SO4 facility,  While there, they were able to observe the production process from start to finish.  They were impressed with the large storage area, bagging equipment, and emphasis on quality control.

Harold, Jeff, Josh & Corbin-thank you for coming to visit.  We enjoyed our time with you!

We are always pleased to introduce our people and products.  If you have questions, or would like to visit, just ask!

Onions & SO4

Take care when applying SO4

I (Glen) decided last week that our garden was needing some calcium.  The soil structure had declined considerably since earlier this spring, and it was becoming difficult to till (hoe).  I was also wanting to increase the quality of the potatoes and reduce the onset of blossom end rot in tomatoes.

Thursday evening I applied SO4.  It was very difficult to get between the rows of potatoes, so I top spread the area, and then turned on the water for 2 hours.  Friday morning, my wife harvested some onions, which were near the potatoes, and was surprised that she couldn't stand to eat them.  She also couldn't stand to cut the tops off of more than 2-3 at a time without tears. 

Conclusion: the sulfur level in the onion had increased significantly.

Lesson learned & a very evident (tearful) demonstration of the solubility of SO4.  In this case, less than 12 hours & 0.4" of water were sufficient for the product to break down & be taken up by the plant.  If you have plants that you don't want to more pungent (radishes, peppers), please take care when applying SO4.

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. 

98g-vs-SO4-Vinegar-Test

 

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.
