Calcite Calcium
Calcite Calcium is produced from high Calcium Carbonate Limestone quarried from underground mines. The particle size, purity and crystal structure of the mineral provide a unique slow release mechanism to predictably provide continuous release of Calcium over time. Calcium helps to build the cell wall structure of the plant.
Greensmiths recommends that a soil test be utilized in determining the proper use, rates and frequency of applications. If no soil test is available, Calcite Calcium may be applied at rates of 5 to 10 pounds per one thousand square feet followed by a soil test.

Internal Surface Area in Calcite Calcium
The solubility of calcium carbonate is
affected by the purity of the calcium and the crystal structure as well as the fineness of
grind. Very fine ground calcium carbonate raises pH very quickly. Dr. Albrecht studied
calcium function in the soil and determined that powdered calcium raised the pH
excessively and leached readily. Greensmiths Calcite Calcium is a pharmaceutical or food
grade calcium that is ground to the particle size that Dr. Albrecht found most effective.
Greensmiths Calcite Calcium is a long term slow release
calcium that supplies the calcium without excessively raising the pH of the soil solution.
Golf greens normally have a very low cation exchange capacity (CEC). The CEC is determined on soil test by adding the millequivalents of calcium, magnesium, sodium, and potassium. Greensmiths Calcite Calcium can be used to raise the CEC of the soil or soil solution.
How to calculate Cation Exchange
Capacity from a soil test.
Divide
Magnesium by 120
Divide
Potassium by 390
Divide
Sodium by 230
If your values are reported in pounds per acre double the divisor ( i.e. calcium 400)
If you are using a saturation paste extract and your values
are milligrams per liter drop a zero from ppm (i.e. calcium 20)
Why Raise the Cation Exchange Capacity?
When the CEC is very low, as in a USGA green, it requires
very small amounts of another cation to alter the balance. Hydrogen, for example can
increase quickly and drop the pH. An application of ammonium fertilizer can alter the base
saturation percentage. Low levels of sodium in parts per million can have a high
percentage of base saturation.
CEC of 2
75% Calcium=300ppm
10% Magnesium 24ppm
5% Potassium=39ppm
10% Sodium=46ppm
Therefore on a soil test where we would like the % of base
saturation sodium to be less than 2% it only required 46ppm sodium to equal 10%
CEC of 6
75% Ca=900 ppm
10% Mg=72ppm
5% K =117ppm
10%NA=138ppm
The Salinity Test or Saturated Paste Extract should be used for maximum accuracy. The extracting solutions used by the laboratory can overstate calcium and magnesium that have varying solubility in the soil.
