Extended abstract 1- Introduction Gypsum, sulfuric acid, and sulfur are used to improve saline and sodic soils. In some cases, animal manures are also used, which varies according to environmental conditions and soil type (Jesus et al., 2019). Industrial gypsum is often used to modify saline and sodic soils due to electrolyte maintenance, physical and hydraulic properties (Keren, 1996), low c...
To identify effective regulatory methods scheduling with the compromise between the soil desalination and the improvement of tomato quality and yield, a 3-year field experiment was conducted to evaluate and compare the effect of straw mulching and soil structure conditioner and water-retaining agent on greenhouse saline soils, tomato quality, and yield. A higher salt removing rate of 80.72% in ...
In situ remediation technologies for contaminated soils are faced with significant technical challenges when the contaminated soil has low permeability. Popular traditional technologies are rendered ineffective due to the difficulty encountered in accessing the contaminants as well as when employed in settings where the soil contains mixed contaminants such as petroleum hydrocarbons, heavy meta...

Saline soils usually cannot satisfy the requirements of engineering projects because their inappropriate geotechnical properties. For this reason, they have always been known as one problematic worldwide. Moreover, lack access to normal water has intensified use saline resources such seawater in many construction and mining projects. Although cement stabilization is frequently used improve prop...
Introduction: Saline soil contains large amounts of soluble salts. In addition to natural factors affecting soil salinization such as climate, topography, and abundance of evaporative formations in the region, the human factors that result from incorrect management of the agricultural system (such as using low-quality water for irrigation, overuse of chemical fertilizers, the frequency of irrig...
Definitions and forms of salinity All natural waters contain soluble salts. The concentration of the salts determines whether the water is of high quality (drinkable or usable for irrigation without need for special precautions) or of low quality (brackish or saline). Water in the soil also contains soluble salts (sometimes called free or nonattached salts). The amount of salts in the root zone...
