Sulfur surprise in soybeans
Twenty pounds of S applied in the form of ammonium sulfate (AMS) close to planting or during early vegetative growth is a good starting point, he observes. Granular AMS is the most straightforward form, but farmers can apply granular S in other ways, such as a 50-50 mix between granular AMS and elemental sulfur.

Gypsum as a soil additive: use it or lose it?
Gypsum has been shown to be effective at treating aluminum toxicity on soils with a pH lower than 4.5. At pH lower than 4.5, aluminum in soil overpowers the ability of hydrogen ions to increase pH. Sulfate may act as a counter ion on soil particles increasing aluminum absorption from the soil solution.

FGD Gypsum Production Process
To make FGD gypsum, the sludge is oxidized by forcing clean, compressed air through it. In the oxidation vessel, calcium sulfite sludge is converted to calcium sulfate (CaSO 4), which almost immediately combines with some of the water in the slurry to form calcium sulfate dihydrate (CaSO 4 ·2H 2 O). The resulting slurry is often referred to as ...
