Iron Toxicity in Plants.

Iron toxicity in plants can occur when the concentration of iron in the soil is too high, or when the pH of the soil is low (acidic). In acidic soils, iron becomes more soluble and available for plant uptake, which can lead to excessive accumulation of iron in plant tissues.


The symptoms of iron toxicity in plants can vary depending on the plant species, but they generally include leaf bronzing, stunted growth, reduced yields, and tissue damage. In some cases, iron toxicity can cause leaf necrosis and death of the entire plant.

Iron toxicity can also lead to an imbalance in other nutrients, such as manganese, zinc, and copper, which can become unavailable for plant uptake when the concentration of iron in the soil is too high.

To address iron toxicity in plants, it is important to reduce the concentration of iron in the soil or adjust the pH of the soil to a more neutral range. This can be achieved by leaching the soil with water, adding lime to raise the soil pH, or adding organic matter to the soil to improve soil structure and nutrient availability. It is also important to avoid over-fertilizing with iron-containing fertilizers, especially in acidic soils. Soil testing and regular monitoring of plant health can help to identify iron toxicity early and prevent further damage to the plants.
