Beans - Deformation
Symptoms
Older leaves turn pale yellow and growing points of young stems wither and die with leaves near to them becoming distorted.
Reasons
Copper deficiency
The availibility of Cu declines above pH 7.0, so it may occur in excessively limed a well as in sandy or organic soils.
Beans - Chlorosis
Symptoms
In the present case younger leaves show interveinal chlorosis.

Beans - Chlorosis
Symptoms
In the present case younger leaves show interveinal chlorosis and a silvery discoloration of some leaf segments near margins and veins.
Reasons
Copper deficiency
The availibility of Cu declines above pH 7.0, so it may occur in excessively limed a well as in sandy or organic soils.
Copper deficiency made worse by
- Organic soils
- Chalky soils
- Sandy soils
- Reclaimed heathland
- High nitrogen applications
Copper is important for
- Better leaf development
- Improved flower set
- Increased yields
