IRON DEFICIENCY
Low Iron status affects younger leaves and active growing points. Similar in appearance to magnesium stress, but affecting new leaves. Tissue becomes severely chlorotic, displaying a uniform interveinal yellowing. Iron deficiency results in reduced tolerance to stress and infection.
SIGNIFICANCE
Iron deficiency restricts the conversion of sunlight to plant energy, resulting in slow growth rates, poor development and low tolerance to both biotic and abiotic stress. Low Iron status is often associated with alkaline soils and cold, wet growing conditions.
ACTIONS
Check soil status and root development for compaction. Apply foliar treatments during the early stages of plant development and times of stress.

Iron deficiency & its importance
January 21st 2021 01:58 pmIron plays an important role in respiratory and photosynthetic reactions. Iron deficiency occurs especially in calcareous, alkaline soils (pH higher than 8.0). Iron deficiency will produce distinctive yellow stripes on leaves of small grains with younger leaves and tissues showing symptoms early. Fruit crops (apples, pears, grapes) will exhibit chlorotic interveinal tissues with major and minor ... Continue reading iron
