What do you see and when?

- Lucerne stunting or patchy poor growth following establishment
- Seen in the first three to four months after establishment
What could this indicate?

- Soil acidity with associated high soil aluminium. This affects root growth, causing stunting, sideways growth of roots and plant loss.
- Waterlogging may cause a similar effect.
What test can I do to confirm?
- Soil test, with reference to pH and aluminium at 0-10, 10-20 and 20-30cm to detect top and sub soil acidity.
