Phosphorus Deficiency vs. Healthy Plant - Raspberry
Symptom description
Dark green coloration of medium and young foliage. Wilting and leaf scorch starting from marginal and interveinal areas of older leaves. Poor branching. Reduced flowering and fruit set, worse fruit quality.
Made worst 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.
Important for
Stronger plants, healthier plants with more resistance to cold weather. Bigger bolder berries. Improves efficiency of fungicide sprays. Reduces incidence of botrytis. Firmer berries with better storage potential. Increases shelf life.
Cause description
Phosphorus deficiency (right) Berries tend to have a low demand for P relative to other crops. Normal leaf level is 0.2-0.6% dry weight. Availibility may be reduced by unfavourable soil conditions such as extremes in pH, temperature or moisture, as well as excessive Ca and Al. Soils with a large quantity of clay will fix more P than lighter soils.
