    NUTRIENT:

    MAGNESIUM

    Hidden in the heart of each chlorophyll molecule is an atom of magnesium (Mg), making the nutrient actively involved in photosynthesis.

    The Power of Magnesium

    Magnesium also aids in phosphate metabolism, plant respiration and the activation of many enzyme systems.

    Mobility

    Magnesium is mobile within the plant and moves easily from older to younger tissues.

    Photosynthesis

    Plants require Mg to capture the sun's energy for growth and production through photosynthesis.

    Magnesium Deficiencies

    When Mg deficiencies occur, the lower (older) leaves are affected first.

    Magnesium Source

    The most common source of Mg is dolomitic limestone, which provides both calcium and Mg, while neutralizing soil acidity.

    Phosphorus Carrier

    Magnesium acts as a phosphorus carrier in plants, and is required for better root formation and thus for better nutrient and water efficiency in plants.

      Magnesium deficiency symptoms

      Symptoms of deficiency can vary across crop species, but similarities exist for how nutrient insufficiency impacts plant tissue color and appearance. Nutrient deficiencies are commonly associated with the physical location on the plant (i.e., whether the symptoms are primarily observed on older versus newly formed plant tissue), but these symptoms can spread as the severity of the deficiency progresses.
