So What is Gypsum Used For?

  • Lawns: In spring and fall you can take advantage of seasonal moisture which will help push an application of gypsum into the soil for conditioning it. Use 10 lbs per 150 square feet.
  • Gardens: Mix well into soil before planting for increased production.
  • For Roses and Flowers: Spade 1/2 lb of gypsum around each plant and soak the area with water. Flowering plants and bushes prefer a more acid soil and by adding gypsum you are lowering the pH of the soil.
  • Trees & Shrubs: In the fall, apply a generous quantity of gypsum to the soil around the base of trees and shrubs to stimulate root growth. This also helps to control insects that hibernate in the soil over the winter.
  • Salt Damage: Winter de-icing salt is toxic to most plants and grasses when it accumulates to certain levels. Use 1/2 lb of gypsum per square foot to restore soil that has absorbed salt.
  • Agricultural use: Farm fields high in clay or sodium will benefit by applying gypsum. Make sure to get a soil test done to find out what your application rates need to be. We have tests and studies to give a better idea of what results can be achieved by spreading gypsum.

Your Soil Will Be Responsive to Gypsum if:

  • Water puddles in your yard, garden or fields
  • There is excessive cracking of the soil after rain or irrigation
  • The soil contains large amounts of clay and is compacted
  • Sodium levels are high
  • You pH from a soil test needs neutralizing. Gypsum can bring both acidic and alkaline soils back to neutral. Can be blended with lime for acidic soils.

What Does Gypsum Do For Soils?

  • Improves soil structure
  • Helps reclaim soils with high salt content
  • Aids in seed emergence
  • Increases the stability of organic matter in soil
  • Improves water use efficiency
  • Helps plants absorb more nutrients

Gypsum Can Be Used for Safe Water Clarification of a Muddy Pond or Lake Water

  • Gypsum (CaSO4) is a water soluble mineral that can be found in fertilizers and mixed in many other products.
  • It is pH neutral, therefore, its application does not have the risk associated with alum treatments.
  • Gypsum works for water clarification by attracting clay particles together to form clumps or what we call floccules.
  • As the clay particles continue to clump they eventually increase in weight and settle to the bottom of the pond of lake.

Gypsum is typically applied at a rate of 1,000-2,000lbs per Surface acre.

Apply gypsum so that it is completely and quickly mixed with the pond water. It should be premixed and pumped or sprayed as a surface slurry or distributed into the propeller wash of an outboard motorboat driven at high speed around the pond. If effective, the treatment should clear the pond in a few days and it should remain clear for months. If not effective, increase the dosage and frequency of gypsum applications.

Gypsum for Soil Remediation, Stabilization or Drilling Mines

Oil and gas drilling sites, superfund sites, mines, landfills, industrial sites such as refineries, smelters, foundries, milling and plating facilities, and other sites with contaminated or disturbed soils exhibit a variety of problems that can often be addressed effectively and directly through the use of gypsum—sometimes combined with other soil amendments.

These problems include:

  • Aluminum (Al) toxicity
  • Poor soil aggregation
  • High sodic levels
  • Lead stabilization
  • Hydrocarbon contaminated soils

Ultra-Fine calcium sulfate dihydrate (gypsum) acts an an inexpensive source calcium in drilling fluids. It is also used as an alternative to lime as a source of calcium when high pH in not desired in drilling mud.

  • Precipitate soluble carbonates from drilling muds
  • Provides Calcium to prevent hydration of shales and clays
