A mineral deficiency is likely to affect older leaves more than younger leaves if the mineral is very mobile within the plant.
How mineral deficiency is likely to affect older leaves?
- Rapid mineral remobilization first causes deficiencies in older leaves. Therefore, elder leaves are the first to display a lack of quickly remobilized components.
- Interveinal chlorosis, a condition where older leaves exhibit chlorosis between veins, is common.
- In cases of severe deficiency, a plant's rate of growth slows, its leaf size shrinks, and its lower leaves fall off.
- Cropped illustration: Lower leaves have dark green veins and are paler and more chlorotic than higher leaves.
- Plants first display signs of molybdenum shortage between the old and new leaves.
- Any nutrient in excess can be hazardous to plants. Salt burn symptoms may arise from using too much fertilizer.
