Phosphoric Acid Plant And Synthetic Gypsum Plant
Diammonium Phosphate | Mosaic Crop Nutrition
It's formulated in a controlled reaction of phosphoric acid with ammonia, where the hot slurry is then cooled, granulated and sieved. DAP handles and stores well. The standard nutrient grade of DAP is relatively high, at 18460, so fertilizer products with lower nutrient content may not be labeled DAP.

Phosphogypsum
Phosphogypsum is a waste byproduct from the processing of phosphate rock in plants producing phosphoric acid and phosphate fertilizers, such as superphosphate. The wet chemical phosphoric acid treatment process, or 'wet process', in which phosphate ore is digested with sulfuric acid, is widely used to produce phosphoric acid and calcium sulfate, mainly in dihydrate form (CaSO 4 · 2H 2 O):

Reducing Soil pH – Wisconsin Horticulture
In these soils, consider growing plant species more tolerant of high pH conditions. Soil pH can be reduced most effectively by adding elemental sulfur, aluminum sulfate or sulfuric acid. The choice of which material to use depends on how fast you hope the pH will change and the type/size of plant experiencing the deficiency.

How we make our fertilizer | Yara International
To produce a phosphorus fertilizer, the rock is treated with acid; sulfuric, phosphoric or nitric. Each method has its advantages and constraints. The sulfuric acid route produces a low phosphorus fertilizer – single superphosphate which is half gypsum. The use of phosphoric acid produces a higher concentration phosphorus fertilizer.
