Copper deficiency vs. healthy plant-Raspberries

Symptoms
Older leaves show interveinal chlorosis, sometimes followed by a faint necrosis. Marginal scorch spreads allover the leaf blade. Total growth is only moderately stunted. Very poor flowering and fruiting.

Reasons
Copper deficiency (right) Levels of 2-50 ppm Cu in leaf tissue are recommened. Cu mobility and uptake may be restricted by high soil pH and excessive P, Zn, and Al. Furthermore, Cu adsorption to Fe, Al and Mn oxides can be significant.
