Made worst by

High pH. Water logged soils. Calcareous soils. High copper, manganese or zinc soils.

Important for

Stronger plants. Healthier plants. Gives plants more resistance to cold weather.

Cause description

Severe iron deficiency on leaves Iron deficient leaf blades contain less than 40 ppm iron on dry basis. May be confused with magnesium or manganese deficiency.
