Add to Cart:

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.


  • Leaches excessive amounts of Sodium (Na) and Magnesium (Mg) from soil colloids.
  • Quicker response at lower rates.
  • 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.

For continued optimum growing conditions, apply Verde-Cal G at 5 pounds per 1,000 ft2 or 220 pounds per acre (2.5 kg per 100 m2 or 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 (5.0 kg per 100 m2 or 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.
