Abstract

Recently, there has been a surge in interest for using gypsum as a management technique to boost agricultural yields and improve soil and water quality. This interest has been fueled by the abundant quantity and availability of flue gas desulfurization (FGD) gypsum, a by-product of removing sulphur from combustion gases at coal-fired power plants, in key agricultural producing regions over the last two decades. Although it is typically cost-effective to employ FGDG as a soil amendment, its application in agriculture is extremely limited when compared to other industries. FGDG has several agricultural applications as a remediation material, including enhancing soil physicochemical qualities, limiting soil and nutrient loss, replenishing trace elements for soil, and increasing crop production. FGDG, on the other hand, contains a number of toxic trace elements. Long-term research of the influence of FGDG on soil health, heavy metal uptake, crop growth and quality, and ongoing monitoring o

Conclusion

As more coal-fired power plants come online and current power plants add SO2 scrubbers to meet with clean air regulations, annual FGDG production will skyrocket. The use of FGDG as a resource material in agriculture has long been recognised. Due to concerns about significant mental harm, such as the presence of toxic heavy metals in FGDG and leaching issues, it is necessary to incorporate FGDG into agriculture more effectively in order to fully exploit its various physical and chemical properties, which are beneficial to soil and crop health. Because it includes a significant number of important nutrients for plant growth, such as macronutrients like Ca, S, and Fe, Mg, and K, as well as micronutrients like Se, Mn, Zn, Cu, B, and Mo, FGDG's potential for usage in agriculture is gaining popularity. It is capable of reclaiming deteriorated soils. Applying FGDG to deteriorated soils can enhance physicochemical qualities, boost plant development, and improve crop quality. As a soil ameliora

INTRODUCTION Sulfur oxides (SOx) are released into the environment from two different sorts of sources: natural and anthropogenic. Geothermal, oceanic, vegetative, and terrestrial emissions are examples of natural sources. Natural sources account for 20% of total sulphur oxides released into the environment, while anthropogenic sources account for the remaining 80%. Sulfur emissions are caused by companies that use high-sulfur-content fossil fuels or industries that use sulfur-containing raw materials (e.g., sulfuric acid and ammonium sulphate manufacturing plants). Sulfur oxides are a primary source of anthropogenic emissions produced by the combustion of coal, crude oil and crude oil-based fuel oil, and gaseous fuels. In 1990, the United States, the Soviet Union, and China were the world's top sulphur dioxide emitters (accounting for over half of the total). Due to varied control techniques, the USSR and the US have stabilised their sulphur emissions during the last 20 years, and cu
