2. Gypsum Helps Reclaim Sodic Soils. Gypsum is used in the reclamation of sodic soils (Aldrich and Schoonover 1951). Where the exchangeable sodium percentage (ESP) of sodic soils is too high, it must be decreased for soil improvement and better crop growth. The most economical way is to add gypsum which supplies calcium. Gypsum is a fertilizer product and supplies the crop-available form of calcium (Ca 2 +) and sulfur (SO 4 2-). If these forms are deficient in soil, then crop productivity will benefit if gypsum is applied. This is a big "if" for Iowa soils. Research has not shown deficiency of Ca and normally any potential problem with low Ca levels is taken ...

In order for gypsum to work properly, it must be well-distributed in the top 8 to 12 inches of the soil. If possible, water the soil after the first application, and then mix it well again. Allow several days for the gypsum to become active, and then test the soil. Gypsum is widely found in soils under arid and semi-arid climates due to its semi-soluble nature. In spite of that, they are less known than other soils, and this has generated some misunderstandings in some initial pedological concepts and in soil classification systems. In addition, the quantification of gypsum, and in particular of its secondary accumulations is affected by the sampling ...

2.5 t/ha, and applying water at a rate of 10 mm/h. Therefore, it should be sufficient to prevent clay dispersion in marginally sodic to sodic soils.
