Solve common lawn problems with SuperCal SO4

We mostly focus on row crops in our blog, however with the first day of spring here and warmer temperatures, many are thinking about their grass.

For much of the Midwest the winter was very long with lots of snow and ice. To keep sidewalks clear lots of salt was used. Excess salt creates growth problems along the edges of sidewalks and streets. SuperCal SO4 is the best product to reduce the harmful effects of salt.

Early spring is a great time to apply SuperCal SO4 to increase water infiltration, improve root growth, and naturally aerate the soil. Applications of SuperCal SO4 improves plant vigor, keeps it greener though prolonged drought periods, provides calcium for reduced fungus, and sulfur for greener grass, and is safe for the environment.

SuperCal SO4 can be safely used at high rates on mature turf grass, but other amendments often must be used at lower rates;

Elemental Sulfur (S), should only be applied at high rates to bare soil as long as it is mixed in and left for a few weeks are allowed for equilibration. During those weeks the soil should be kept moist and soil temperatures should be above 55 degrees to allow biological conversion of S into H2SO4. Elemental S and other S sources (except gypsum) should not be applied to a mature turf grass above 5# S per 1,000 sqft to avoid foliar burn and excessive acidity at the soil surface. Sulfur fertilizers containing N are limited per application by the turf grass N requirement.

It is always best to start with a soil sample before applying any fertilizers or amendments. Once a need for SuperCal SO4 has been established use at the following rates;

Established Lawns:
40#'s per 1000 sqft applied spring and fall thoroughly watered in.

Salt affected areas:
After initial spring application, frequent applications of 10-15 lbs. per 1,000 sq. ft. throughout the growing season may be required to maintain optimum growing conditions. Final rates should be determined on the basis of a soil test.

New Seeding and Sod:
Apply 100 lbs. per 1,000 sq. ft. prior to seeding or sodding. Water thoroughly.

Heavy Clay or Compacted Soil:
Spread 100-150 lbs. per 1,000 sq. ft. annually in the spring and fall to maintain soil condition. Water thoroughly.

Applying SuperCal SO4 to your yard will ensure it stays green, reduce your water bill, and make you the envy of your neighbors.

Sodium, salinity & soil, Not A Good Combination

Does your soil need a salt shaker?  Probably not, although it can happen through application of manure and/or byproducts that may contain sodium (Na) or excess salt (salinity), and through irrigation water.

Sodium has a dispersive effect on soil clays.  It can cause the clay particles to separate from each other, the particles will clog the soil pores, and cause a thin layer of slowly permeable material near the soil surface.  This effect is more serious in fine-textured soils than in coarse textured.  Soils with a high water table or poor drainage are more susceptible to salt or sodium accumulation.

Salinity can make plants work harder.  They must expend more energy to extract water from the soil.  Excess salinity can retard cell enlargement and division, as well as the production of proteins.  

Visible crop injury symptoms, such as leaf burn, are likely to occur only at high salinity levels.  However, yield losses can occur at lower levels, depending on the crop's sensitivity.  Corn & alfalfa are classified as "moderately sensitive", while soybeans are classified as "moderately tolerant."

Have more questions?  Start with a soil test.  If you or your agronomist suspect this may be involved, then talk with the lab where the samples are going.  I recommend Midwest Labs (, but most labs will be able to help you with this.  They may have specific guidelines that they recommend following to help you identify what is going on.

How to safely remove salt from your soil

Hurricane season has arrived and the experts are expecting a very busy season. Not only do these types of storms leave immediate damage to properties in the form of flooding, wind damage, power outages but it can leave lasting damage to your turf and plants by increasing the amount of salts or sodium to your soils.

Unless you have salt-tolerant grass or plants, which most people do not, high levels of salts can be very devastating to your landscapes. Increased levels of salt act as a barrier to the plant’s cell wall, in essence tricking it into thinking it is in a drought situation even it there is plenty of water. When the plant can’t absorb the water in the soil it will shut down and go into dormancy and eventually will die due to lack of hydration.

There are a few ways to combat the salt issues if you don’t landscape with salt-tolerant plants and turf. You can spend time flushing the areas with clean water until the salts have been leached out of the ground. This takes an extreme amount of water to fully leach out the salts out of the root zone and is an irresponsible use of water in this age of conservation.

The safest, healthiest and most cost efficient way to rid your soil of high levels of salt is to use gypsum. But not just any gypsum, it has to be a calcium sulfate di-hydrate (CaSO4*2H2O). This form of gypsum is by far the most soluble form available. The best calcium sulfate di-hydrate gypsum on the market, SuperCal SO4 by Calcium Products, is extremely effective and efficient in correcting your high sodium levels in the soils.

Application of SuperCal SO4 is very easy. It comes as simple, clean, uniform pellets that can be spread using a broadcast or drop spreader. It is to be topically applied to the turf; for best results follow the application with a light watering to assist in the breakdown of the pellets. Because it is a naturally mined material it can be applied anytime during the year, regardless of the temperature. It will not burn the grass or affect the pH.

For the leaching of the salts due to extreme weather or due to high sodium levels from other factors, increase the suggested application rates from 5-10 pounds per thousand square feet to 20-30 pounds per thousand square feet.

Before long your turf will be thanking you; it will not only be salt free but healthier, stronger and more resistant to drought and disease pressures because the calcium strengthened the cell wall and increased the immune system of the plant.
