  • Soil acidification Wikipedia

    Soil acidification is the buildup of hydrogen cations, which reduces the soil pH.Chemically, this happens when a proton donor gets added to the soil. The donor can be an acid, such as nitric acid, sulfuric acid, or carbonic acid.It can also be a compound such as aluminium sulfate, which reacts in the soil to release protons.Acidification also occurs when base cations such as calcium, magnesium
