Symptoms of iron deficiency start on younger leaves. Plants show chlorotic leaves with interveinal stripes. When the deficiency becomes severe the veins also become chlorotic and plant growth is stunted.
High pH. Water logged soils. Calcareous soils. High copper, manganese or zinc soils.
Healthy green foliage. Improved yield and grain quality.
Iron deficiency Can be confused with manganese deficiency, but manganese deficiency is very rare in corn. Magnesium deficient plants also show interveinal chlorosis, but the symptoms start on older leaves.
