Bicarbonates The fate of calcium and other cations

Bicarbonate Interaction in Your Soil

Bicarbonates have a strong affinity to nutrients, especially available calcium.

Fate of Calcium when it becomes soluble

  • Taken up by plant
  • Interact with the soil colloid
  • Leach
  • Bond with Bicarbonate forming Calcium Carbonate

The bonding of available Calcium with Bicarbonates is due to the positive charge (cation) Calcium and the negative charge (anion) of the Bicarbonate.

The result of this is, the plant works a lot harder to grow a lot less!

Once Calcium Carbonate (CaCO3) is formed pH and sodium levels will begin to increase in your soil. Magnesium, Potassium and Hydrogen will decrease. All other nutrients will become unavailable.

Crystalline and Angular Structure of CaCO3

The angular structure of CaCO3 will result in a "Stacking" and "Inter-locking" effect increasing sodium levels near the surface of your turfgrass system and a "sealing off effect".

The image above shows an increased area of sodium causing a sealing off effect from the "stacking" and "inter-locking" of the angular CaCO3.

Correcting high Calcium Carbonate and Sodium levels

Remember, issues related to Calcium Carbonate and Sodium took time to develop. It is going to take some time to mitigate.

How do you dissolve what has become insoluble?

Applying a strong acid will dissolve and put the Calcium Carbonate back into solution.

AcidipHy Benefits

  • Apply at a rate according to your Bicarbonate levels in your water.
  • Contains 4 different acids
  • Contains Manganese

Our rates are realistic vs. the severity of the problem. We don't subscribe a standard rate as the severity of the problem dictates the amount of acid required to correct the issue. This statement is true regardless of your choice of acid product.

Use a carrier of at least 2.5 gals per 1000sqft and water off the plant after application. Be sure to irrigate that evening with enough water to flush your soils.

OARS PS Benefits

  • Help efficiently to drive the AcidipHy into your soil profile
  • Redistribute organic acid buildup on your soil colloid


  • Reduces sodium levels
  • Dry lime chelator
  • Provides a uniform calcium profile

Redi-Cal addresses both the plant’s calcium needs, as well as the growing media pH.

Following this application you will see a visual improvement in your turfgrass.

  • Calcium have been flushed from the soil
  • Sodium levels have been lowered
  • Other nutrients now become available to the plant

Important to follow-up

Using Verde-Cal G will allow you to continue to lower your Sodium levels and regain balance in your soils.

Using Verde-Cal K Plus will return nutrients you were concerned about losing during the flush

You can continue with these programs as often as needed to continue to reduce your Calcium Carbonate issues. Remember to continue to soil and water test! For additional information or assistance with your programs, we invite you to contact us below.
