Chloride
One piece of the salt. Chloride-sensitive crops ask this cell on its own.
Also called: Cl-, water-soluble chloride
Speed
- Chloride is one piece of the salt.
- Sensitive crops ask this cell alone.
- Scorched margins: split salt from potassium.
- Don’t feed KCl when Cl is already high.
How it appears on the sheet
The sheet says chloride or Cl-, often mg/kg.
A sketch. Do not fertilise from the picture alone.Common units
Chloride often mg/kg or cmol/kg. Read with total salt and EC.
Soil:water ratio · Read with EC and total salt. High Cl: do not feed KCl.
How to read the number
High chloride is a salt clue, not an order to add potassium.
Rates live in the saline or potassium guides — split salt from K first.
Thresholds only, not a prescription. Rates live in the field guide. This page does not hand you a bag count.
| Cell | Low | Mid | High |
|---|---|---|---|
| Chloride (sketch) | Most crops don’t mind | Ask if the crop hates chloride | A salt clue; stop KCl on sensitive crops |
Regional classes differ. This table is a comparison, not a prescription.
What it looks like in the field
Scorched margins: ask if the soil is white, and whether a chloride fertiliser went on.
Don’t do this
- Don’t treat Cl as a K gap.
- Don’t use KCl on chloride-sensitive crops.
- Don’t flood-wash at the first scorched edge.
