Iron deficiency Iron is the micronutrient needed in greatest quantities within brassicas, but deficiencies are rarely seen. Lack of Fe is most frequent on light, alkaline and calcareous soils with low organic matter. However, soils with peat substrates have a naturally low Fe content. High P fertilization may also induce Fe deficiency.

Iron deficiency made worse by

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

Iron is important for

Early leaf development and crop productivity
Needed in relatively large amounts
