Cabbage - Growth retardation
Symptoms
P deficiency results in severe growth reduction. Plant color and habitus are not affected.
Reasons
Phosphorus deficiency (right)
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
- Early growth, especially for root development
- Increases vigor in shorter season crops especially in adverse conditions
- Improves marketable yield
