Enhancing the Characteristics of Gypsum Soil by Adding Hydrated Lime
Gypsum soils extend approximately 100 million hectares globally, equivalent to one million square kilometers. These soils are found in various regions such as Iraq, Syria, Libya, Somalia, Algeria, Sudan, Argentina, Australia, Spain, the former USSR, and other semi-arid and arid nations with an annual rainfall of fewer than 500 millimeters [1].

In soils containing calcium carbonate, alternatives to gypsum can be effective. Mineral lime (calcium carbonate) in these soils can be converted to gypsum by adding sulfur, sulfuric acid, or other acidic or acid-forming materials (see Table 1 for equivalent quan-tities of various soil amendments). The acid dissolves the calcium

Use of Gypsum to Reclaim Salt Problems in Soils
It is recommended to spread gypsum on soils as an application through low-volume irrigation sources (i.e., drip and sprinklers) and is shown to work best with irrigation water of low salinity, i.e., about 0.1 ds/cm. Liquid gypsum application can increase the water infiltration to greater depths under the emitters over time due to soil particle ...

Influence of Gypsum Enhanced Chicken-Manure-and
The use of gypsum to ameliorate soil sodicity is a typical practice in Australian agriculture. However, the longevity of ameliorative effect due to gypsum application is often short, due to the rate of dissolution and subsequent leaching by rainfall and/or irrigation. Gypsum was combined with chicken manure/wheat straw compost, during the composting process, in order …
