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 …
Flue gas desulfurization (FGD) gypsum and straw return have been recognized for their roles in reducing soil sodicity and improving soil organic matter. However, there are few studies on the effect of their combination on improving and fertilizing sodic soil. FGD gypsum at a rate of 15 t ha−1 and three types of straw (sunflower seed …
Due to its abundance, purity, chemical and physical properties, and similarities to natural gypsum, FGDG is being used in several beneficial applications in two different forms: encapsulated and non-encapsulated.
