Manganese

Deficiency Symptoms

Leaves become chlorotic in interveinal areas while the veins remain green. Symptoms differ from Fe where the veins also become chlorotic. Whole leaves, veins excepted, become pale green and pale yellow. Brown spots and necrotic areas develop on lower leaves as the deficiency becomes more severe. Deficiency occurs on the new leaves, however, when later growth is normal the chlorotic leaves are no longer at top of the plant.
