- The soil surface is white; seedlings come up in patches
- Wheat in Hebei. A white powder on the soil. After a light watering they wilt more. Drought or salt?
- A white crust is a salt clue, not proof by itself. Worse wilt after a light watering is not a reason to flood. No drain, no flood. Stop high-salt fertiliser. Read EC, pH and total salt — saline and alkali are different jobs. Don’t spread gypsum on every white crust.
