Nutrients

Cereals - Growth retardation

Symptoms
Plants are stunted and show purple tints on their dark green leaves, veins and stems. The older leaves, affected first, often senesce prematurely.

Causes
Phosphorus deficiency Spring cereals may show reddening/purpling of older leaves in cold weather. Root and stem damage or poor soil consolidation can cause similar symptoms, too.

Phosphorus deficiency made worse by

Acidic or very alkaline (calcareaus) soils
Low organic matter
Cold or wet conditions
Crops with a poorly developed root system
Soils with low P reserves
Soils with a high phosphate capacity
Iron rich soils

Phosphorus is important for

Better crop establishment
Improved early root development
Improved yield
Even crop maturation
