Symptomer
Manganese deficiency is first seen as light green spots on leaf margins and as an interveinal mottling.
Usually the recently matured leaves in early summer growth are the first to show symptoms. Interveinal areas then become yellow, with prominent green veins.
When severe, leaves and shoots become stunted although generally there is little change from normal leaf size and shape.
