May 25, 2012· Unlike gypsum and calcium sulfate anhydrite, lime solubility is dependent on soil pH. Its solubility increases in acid soils and decreases as soil pH increases. When soil pH is above approximately 8.2, lime becomes quite insoluble. This is why most soils with a …


If free lime is present in the soil, it can be dissolved by applying sulfur or sulfuric acid. Sulfur products reduce the pH which dissolves the lime, thus freeing up the calcium. If free lime or gypsum is not present in adequate amounts as determined by a soil test, then add calcium. The most common form of calcium used for this purpose is gypsum.


Gypsum is a unique material that performs well as a soil amendment. Gypsum, chemically known as calcium sulfate dihydrate (CaSO 4 • 2H 2 O) readily dissolves to release calcium ions (Ca +2) and sulfate-sulfur ions (SO 4-2). Gypsum application benefits. Rehabilitation of high sodium, magnesium and aluminum impacted soils.

GYPSUM & LIME

Lime is a slow setting material; it takes a considerable time to gain rigidity. Setting time of lime is affected by: • the humidity and CO 2 content of the air (Setting time of lime is longer when the amount of moisture in the air is high and when the amount of carbon dioxide is low). • the amount of CaO present in lime.


Application General Prior to use of any additive,good job practice involves mixing a trial batch of formulated product and determining the set time.Once the set time is known,a measured amount of USG Retarder/water mixture is added to adjust the set.Any available container (wax cup,coffee can,measuring cup,etc.) can be used to measure the retarder/water
