• Soil Manganese in Relation to Plant GrowthScienceDirect

    From the results of several investigations involving manganese toxicity it has appeared that manganese toxicity is one of the main causes of soil acidity injury to plants. Aluminum toxicity and lack of available calcium magnesium or molybdenum may also affect plant growth in certain acid soils. Previous chapter.

  • Manganese in plants and soil Cropaia

    Manganese is available in soil pH lower than 7.0. At soil pH lower than 5.5 manganese toxicity might occur. At a higher soil pH low-solubility manganese compounds form and manganese solubility is reduced. Furthermore at high soil pH a higher rate of manganese adsorbs to soil particles and as a result its availability to plants decreases.
