Iron Deficiency

From the HORT402 manual

Chlorosis observed in iron-deficient plants is often a secondary effect from Fe interactions with other nutrients. Younger leaves of Fe deficient plants show the most intense chlorosis. Severely deficient leaves are yellowish or almost completely white as they unfold.

Symptoms

• Bright yellow chlorosis of the younger leaves
• Browning of the roots
• Roots smell differently

Important processes

• The roots excrete phenolic compounds coloring the roots brown and giving the roots a typical smell
