Symptoms
Boron deficiency symptoms start on the younger leaves. They remain small, are curled down and become deformed. The leaves show chlorotic mottling on the edges and between the veins. Necrosis may appear on leaf margins and intercostal fields.
In case of ongoing deficiency only light heads are built and plant growth is severely stunted.
Reasons
Boron deficiency on white cabbage
Boron is readily leached in sandy soils, particularly those in the tropics with low soil pH, CEC or low organic matter contents.
Brassicas need B in relatively large amounts.
Symptoms
In case of ongoing B deficiency only light heads are built and plants show a rather loose habitus. Leaf color is brighter than usual.
