Soil
Soils with a pH level of or lower are considered critical and should be treated to increase the pH level to or higher. Maintenance appliions should consist of applying Limestone annually or with each full crop cycle. Similarly gypsum may be used at corresponding rates to lower pH reading or as advised from soil test.

The Principles of pH
To lower pH, brewers often add calcium ions, from gypsum (calcium sulfate) or calcium chloride. In a 5gallon (19L) batch, one or two teaspoons of either of these will often solve the problem. Likewise, organic acids — such as lactic acid or phosphoric acid — can be added to directly lower mash pH.

Notes on the Gypsum Requirement (GR) of Soil
This article provides a notes on the Gypsum Requirement (GR) of soil. The main principle for the reclamation of sodic or alkali soils is to replace exchangeable Na by another ion calcium (Ca 2+).Of all calcium compounds, gypsum (CaSO 2 O) is considered the best and cheapest for the reclamation purpose. Calcium (Ca 2+) solubilized from gypsum replaces sodium (Na +) leaving soluble ...

SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g). When wet scrubbing with a Ca(OH) 2 (hydrated lime ...
