• Magnesium sulfate (Epsom Salts) is soluble but calcium sulfate (gypsum) isn't (Rule C). These rules are also helpful in determining the compatibility of fertiliser salts in solution, by considering the solubility of any potential reaction products. For example: • Ammonium sulfate and calcium nitrate are soluble (Rule A).Web
