Acidic soil is most suitable for the growth of plants.
Basic soil
Plants do not grow well when the soil is either too basic or too acidic. Plants grown in acidic soil can experience a variety of symptoms including aluminium (Al), hydrogen (H), and/or manganese (Mn) toxicity, as well as nutrient deficiencies of calcium (Ca) and magnesium (Mg). Aluminium toxicity is the most widespread problem in acid soils.
