Verde-Cal G (Enhanced Gypsum)

Calcium Sulfate (gypsum) is combined with thCa™, an organic complexing agent. thCa™ makes the Calcium (Ca) in gypsum more readily available for soil or plant use without effecting or raising pH.


  • 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.

  • Supplies plant available Sulfur (S) in the sulfate form.

  • Improves soil aeration and water percolation.

  • Ideal for turf, shrubs, and flowers.

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


For continued optimal growing conditions, apply VERDE[1]CAL® G at 5 pounds per 1,000 ft2 or 220 pounds per acre (250 kg/ha) 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/ha) 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/ha) every month during the growing season.
