Broccoli - Necrosis

Symptoms
Symptoms of calcium deficiency start on young leaves. They develop necrotic lesions on leaf tips and margins. With ongoing Ca deficiency necrotic areas progress from tips and margins inwards.

Reasons
Calcium deficiency on broccoli leaf Most soils contain enough calcium, but restricted uptake leads to calcium deficiency. High content of ammonium, potassium, magnesium or sodium in the soil and water stress (deficiency or excess) induce calcium deficiency. Adequate Ca nutrition is crucial for crop quality and minimizes clubroot.
