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.
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.
Check soil status and root development for compaction. Apply foliar treatments during the early stages of plant development and times of stress.
