A high water table: the soil never dries, the root never goes deep
That is a drainage job, not a fertiliser job.
- A pit weeps water in minutes.
- The surface looks dry; underneath it is drowning.
- Roots stay shallow.
- Hard packing is hard; a high water table is wet.
- Shallow roots cannot eat deep — it looks like a shortage.
- Don’t subsoil a high table into a dirty-water trench; don’t irrigate it as drought.
- Drainage: Drop the water table below the root layer. Follow local engineering
- Name what you see before you feed.
- If leaves, roots and the surface disagree, stop.
What you see in the field
A pit weeps water in minutes. The surface looks dry; underneath it is drowning. Roots stay shallow.Is the soil wet or dry, the root white or black? Wet wilt and a foul root mean drain first. Leaf wilt with white roots may be drought. Smell the root before you irrigate.

Why it looks like this
The field looks like this because the root cannot take water or nutrients the usual way. Fix the soil condition first — drainage, salt, acidity, compaction or a salt of fertiliser — then a thin feed. Rates live in the range on this page; confirm with a local station and the label.
Easy to mix up
Looks like “Ordinary hard packing”
Hard packing is hard; a high water table is wet.
Looks like “Short of fertiliser”
Shallow roots cannot eat deep — it looks like a shortage.
Do this / don’t do that
- 1A pit weeps water in minutes. The surface looks dry; underneath it is drowning. Roots stay shallow.
- 2Ditch and drop. Use a shallow-rooted crop as a bridge. Don’t send all fertiliser to a depth that stays drowned.
- 3Don’t subsoil a high table into a dirty-water trench. Use the range on this page only as a range. Confirm with a local station and the product label.
Don’t do this first
- Don’t subsoil a high table into a dirty-water trench; don’t irrigate it as drought.
