Flue gas desulfurization (FGD) gypsum, a coal combustion by-product, can be used to decrease water-extractable soil P, thereby lowering the potential for P export to surface waters. This decrease results from a conversion of loosely bound inorganic P (IP) which is readily desorbable to water, to less soluble Al- and Fe-bound IP and, to a lesser extent, …

Long-term use of gypsum or using rates higher than given in the criteria can have adverse impacts on soil or plant systems. This can include: • Where gypsum-derived products are alkaline due to impurities, raising the soil pH to a level that is detrimental to plant growth or nutrient balance
— In addition, gypsum can help reduce the amount of phosphorus that enters waterways. Phosphorus is an essential nutrient for plant growth, but excess phosphorus can lead to harmful algal blooms in waterways. Gypsum helps reduce the amount of phosphorus that is available for plant uptake, which can help prevent harmful algal blooms.
