Why chloride shortage is rare but chloride excess from saline water is common, what each looks like, and what to do in each case.
Chloride shortage is rare in the field: it shows as wilting leaf tips, pale leaves and stubby roots. Chloride excess, from saline water or soil, is far more common: older leaves burn at the tips and edges, then drop. Testing the irrigation water and soil tells you which you have.

Crop by crop
| Crop | What you see |
|---|---|
| Coconut | One of the crops that responds to chloride; muriate of potash supplies it. |
| Potato | Excess chloride can lower dry matter and processing quality of tubers. |
| Tobacco | Excess chloride harms leaf burning quality. |
| Grapes and citrus | Sensitive to chloride: leaf edge burn on saline water. |
| Pomegranate and vegetables | Leaf tip burn and slow growth on saline irrigation water. |
Side by side
| Shortage (rare) | Excess (common) | |
|---|---|---|
| Leaves | Wilting tips, pale, bronzed | Burnt tips and edges of older leaves |
| Roots | Short, stubby, thick | Weak, salt-stressed |
| Where | Leached sandy soils with no chloride input | Saline water, coastal and saline soils |
| Fix | Chloride fertilizer | Drainage, leaching, sulphate of potash, tolerant crops |
Confirm and correct
- Confirm with a soil or leaf test before you spend.
