Both gypsum and lime are used as soil amendments. The usefulness of comparing them is limited because their function is different. Gypsum is added to clay and heavy soils to help them drain and improve their tilth, or ability to be tilled, and to remove salt from saline soils. 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.

Quicklime (CaO), which is made by heating limestone that is changed into slaked lime by carefully adding water, is the great base of chemical refinery with countless uses. When mixed with sand, it hardens mortar and plaster by taking up carbon dioxide from the air. Calcium from limestone is an important element in Portland cement.

This scatter might be due to the nature of the lime and gypsum, which are both much softer than limestone and therefore yield more variation in the particle size when it is ground. The graph for the gypsum can still be used to get a reasonable estimate of the BET surface area from a Blaine measurement, but the lime graph is of no practical use.

Gypsum Recommendations Soils containing more than 15% exchangeable sodium are prone to poor drainage and salt buildup. Application of a soluble source of calcium, such as gypsum, is recommended to replace the sodium off of the exchange sites and be leached out of the root zone.
