Beans - Growth retardation
Symptoms
Young leaves show a yellow chlorosis on intercostal and marginal tissue, older leaves can display a yellowgreen mottling and marginal necrosis. Growth is stunted with deformed, crumpled leaves when deficiency is severe. Terminal blossoms may get brown and die off.
Reasons
Zinc deficiency (right)
Zinc availibility is best in the pH range 5.0 - 7.0. Soil compaction, low content or excess application of organic matter can inhibit Zn supply. High absorption of other nutrients, such as Fe, can also induce Zn deficiency.

Zinc deficiency vs. healthy plant made worse by
- Organic soils
- High pH soils
- Soils rich in phosphorus
- Soils receiving high phosphorus application
- Cold wet conditions
Zinc is important for
- Better plant growth and leaf development
