How to repair sodic soils

Sodium problems are becoming more widespread

Sodic soils are one of the most difficult challenges facing turf managers in areas where they exist. With the rise of effluent water use for golf course and athletic field irrigation, sodium problems are becoming more widespread than they were in the past. High levels of sodium create a toxic environment for plant health and destroy the physical structure of soils.

Sodium becomes a problem when it reaches levels that overwhelm the natural equilibrium of the soil. It causes soil clay particles to swell and disperse, causing soil pores to become blocked, limiting water infiltration and drainage of the soil. Plants trying to grow in sodic soils exhibit symptoms of drought due to excessive uptake of sodium and lack of water infiltration into the soil where roots normally grow.

Check out our document on using SO4 and 98G to manage sodium affected soils.

Del Norte High School in San Diego, California

Below are before and after photos of Del Norte High School's baseball field in San Diego, California. After extensive soil testing, it was identified that sodium levels were at toxic levels for quality turfgrass growth and that the Calcium/Magnesium ratios were dramatically off. 98G, our pelletized limestone, was applied at 10 lbs/1000 ft2 every three to four weeks from June to November for a total of about eight applications.

Meet our Updated Product Names and Logos

 

We have some exciting news to share! We are shortening our product names to 98G and SO4 and have created a new logo for each. Yes, we are retiring the “SuperCal” language in an effort to simplify the product names for more clear communication.

We are committed to growing brand recognition for 98G and SO4, and we’ll be updating materials over the next year.

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.

Take the 98G Challenge – See How Your Aglime Stacks Up.

Challenge Blog Image

Do you know how effective your aglime is in changing soil pH?

Below are two photos comparing 98G, our pelletized lime product, to aglime being spread in a field near Boxholm, Iowa. The photos illustrate that the finest particles in aglime, although the most effective at changing soil pH, are subject to significant drift loss.

98G is pelletized for uniform distribution out of application equipment resulting in ideal spread and solubility. It also has the ability to be mixed with other dry fertilizers.

Learn more about the 98G Challenge and request an aglime sample collection kit.

Soil pH – The Foundation for Nutrient Availability

Soil pH Blog Image DRAFT1

Every nutrient's availability is affected by soil pH.

Soil pH is the foundation and main governing parameter of soil fertility. Every nutrient’s availability to plants is affected by soil pH – some more so than others – which is why correcting and maintaining soil pH at adequate levels is so important.

Phosphorous (P) availability is the most affected nutrient by pH because the chemistry of P is such that it loves to react with other minerals in the soil at varying pH levels. At high pH, P is very attracted to calcium, while at low pH, P is very attracted to aluminum and iron. When P reacts with calcium, aluminum, or iron, it forms insoluble compounds that plants cannot easily access.

Nitrogen (N) and Potassium (K) are also affected by pH, but not in the same way as P. At low pH, aluminum and iron increase in availability and “out-compete” nutrients like N and K in the soil, leaving N and K susceptible to leaching from the soil profile.

Maintaining proper pH protects fertilizer investments.

With the substantial investment made on N, P, and K fertility programs, it is easy to see why maintaining appropriate pH is paramount to protecting fertilizer investments. Further, crops need sufficient access to these nutrients in order to obtain maximum yield and further return the investment growers make on these important nutrients.

Our philosophy is that soil pH should be corrected and then maintained with yearly or every-other-year, lower rate applications to avoid the pH rollercoaster that can occur with 4- or 5-year aglime application regimens. Our product, 98G, is a pelletized lime that corrects and maintains soil pH. It’s easy to apply and works well in variable rate application programs.

By measuring and managing soil pH, you are ensuring that growers are set up for a high-yielding crop and fertilizer investments are being put to work.

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.

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.

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!
