The soil pH of my fields ranges from 5.8 to 6.3. Can ammonium sulfate improve phosphorus availability even under these slightly acidic conditions?


Yes. Since calcium phosphate may precipitate when soil pH is more than or equal to 5.5, ammonium sulfate’s acidifying effect may help improve phosphorus availability in your soils.
