Iron (Fe):

• A key catalyst in chlorophyll production. Deficiency turns new leaves pale yellow or white while the veins remain green.
• Difficult for plants to absorb and moves slowly within the plant.
• High pH prevents plants from absorbing Fe

Manganese (Mn):

• Works with plant enzymes to reduce nitrates before producing proteins.
• Lack turns young leaves a mottled yellow or brown.

Boron (B):

• Necessary for cell division and protein formation; also for pollination and seed production.

Chlorine:

Copper (Cu):

• Catalyst for several enzymes.
• Deficiency makes new growth wilt and causes irregular growth.
• Excess causes sudden death of plants.

Molybdenum (Mo):

• Helps form proteins; assists fixing nitrogen from the air.
• Deficiency causes leaves to turn pale, with scorched-looking edges, and to grow irregularly

Zinc (Zn):

• A catalyst: must be present in minute amounts for plant growth.
• Defienciency produces stunting, yellowing and curling of small leaves.

General Functions: Needed by all plants but especially useful for any plant subjected to stress, such as seedlings you are setting out, transplants, and victims of drought or other damage. For details see The Golden Acre Guide to Nutrients.
