Plants may exhibit typical Mg deficiency symptoms, and when in high excess, K deficiency may also occur. Older leaves will be yellow in color with interveinal chlorosis (yellowing between the veins) symptoms. Plant growth will be slow and some plants may be easily infested by disease.
Brief description of deficiency symptoms seen in plants:
- Macro nutrients: Nitrogen
Deficiency symptoms: Yellowing of leaves, stunted growth, Dormancy of lateral buds.
- Macro nutrients: Phosphorus
Deficiency symptoms: Delay in seed germination, Appearance of leaves in dull green in color.
- Macro nutrients: Potassium
Deficiency symptoms: Loss of apical dominance and cambial activity, Shorter internodes, plastid degeneration.
- Macro nutrients: Calcium
Deficiency symptoms: Necrosis of young meristamatic regions like root tips, leaf tips become hooked.
- Macro nutrients: Magnesium
Deficiency symptoms: Cholorosis between leaf veins, Premature leaf abscission.
- Macro nutrients: Sulphur
Deficiency symptoms: Accumulation of anthocyanin.
Micro nutrients- Deficiency of Symptoms
- Iron - Cholorosis of young leaves.
- Manganese - Interveinal Cholorosis and grey spots on leaves,
- Zinc - Malformed leaves and stunted growth.
- Copper- Necrosis at the tip of the young leaves.
- Boron- Death of root and shoot tips, Loss of apical dominance.
- Molybdenum- May cause nitrogen deficiency, slight retardation of growth.
- Chlorine- Wilted leaves, stunted root growth, reduced fruiting.
