Phosphorus deficiency on orange 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

Vegetative growth increased
Leaves are much greener
Fruit set is increased
Yield boosted, fruit quality enhanced (sugar/acid improved)
Particularly important in young trees with poorly developed root systems
