Phosphorus deficiency-Raspberries

Symptoms
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.

Reasons
Phosphorus deficiency 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.
