Enhanced Nutrient Absorption. Enhanced Nutrient Absorption is a crucial aspect of using ammonium sulfate fertilizer in agriculture. The unique chemical structure of this fertilizer plays a significant role in promoting efficient absorption of nutrients by plants, ultimately leading to improved yields and plant health.
A high-purity grade of ammonium sulfate often works best for this purpose to avoid plugging spray nozzles. Management practices. After addition to soil, the ammonium sulfate rapidly dissolves into its ammonium and sulfate components. If it remains on the soil surface, the ammonium may be susceptible to gaseous loss in alkaline conditions.

The preparation of composite materials by synergistic utilization of different substances and FGD gypsum is another focus of current research. Many …
Millions of tone of FGD-gypsum by-product may be produced in this decade as a result of the 1990 Clean Air Act Amendments. In this research, bench-scale experiments were conducted to obtain process data for the production of ammonium sulfate from FGD-gypsum and to help evaluate technical and economic feasibilities of …
In the Ammonia Sulfate (AS) process, the absorption of SO 2 is accomplished with either anhydrous or aqueous ammonia and converts the captured SO 2 into a high value crop fertilizer. This advanced technology provides a unique solution enabling power generators to achieve regulatory compliance producing significant revenues by the sale of AS …
CIPS will provide technical assistance and samples of FGD-gypsum for the project. In this quarter, a literature study that should give detailed insight into the chemistry, process schemes, and costs of producing ammonium sulfate from gypsum is in progress at the ISGS. Acquisition of a high quality FGD-gypsum sample was completed.
