    NUTRIENT:

    CHLORINE

    Plants take up chlorine (Cl) as the chloride (Cl-) anion. It’s active in energy reactions in the plant. Most Cl- in soils comes from salt trapped in parent materials, marine aerosols and volcanic emissions.

    Micronutrient

    Classified as a micronutrient, Cl- is required by all plants in small quantities.

    Stomatal Regulation

    Stomata regulate the release of moisture from plants so they can minimize water loss during stressful dry periods. Chloride is key in stomatal regulation.

    Chemical Breakdown of H₂0

    Chloride is involved in the chemical breakdown of water in the presence of sunlight and activates several enzyme systems.

    Osmotic Adjustments

    Chloride plays an important role in plants as they acclimate to changing water availability (or make osmotic adjustments).

    Transport of Nutrients

    Chloride supports the transport of nutrients such as calcium, magnesium and potassium within a plant.

      Chlorine 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.
