Verde-Cal G

Gypsum Enhanced with thCa™
Verde-Cal G

Calcitic limestone combined with thCa™, an organic complexing agent, converts insoluble Calcium (Ca) compounds to soluble and available Calcium (Ca). This allows for greater delivery of Calcium (Ca) to the exchange sites on the soil colloid.

500 pounds will yield results equivalent to 1 ton of typical gypsum.

Leaches excessive amounts of Sodium (Na) and Magnesium (Mg) from soil colloids.

Supplies Calcium (Ca) without raising pH.

Helps loosen compacted, heavy clay soils.

Excellent source of Sulfate Sulfur. Readily available to the soil and plant

Improves soil aeration and water percolation.

Ideal for turf, shrubs, and owers.

Quicker response at lower rates. Requires 1/4 the rate of standard gypsum per application. 

Application Rates

For continued optimum growing conditions, apply Verde-Cal G at 5 pounds per 1,000 ft2 or 220 pounds per acre (250 kg per hectare) monthly through the growing season, or as needed. Soil test recommendations should be followed.


To correct high sodium or magnesium levels or to loosen clay soils, apply Verde-Cal G at 10 pounds per 1,000 ft2 or 435 pounds per acre (500 kg per hectare) once or twice per growing season, or as needed. A follow up soil test is recommended and reapply, if needed, at optimal growing condition rate.


To correct high sodium levels on Greens and Tees or when using effluent water, apply Verde-Cal G at 8 pounds per 1,000 ft2 (400 kg per hectare) every month during the growing season.
