An improved soil test for copper deficient soils locations

To improve the soil test for available copper in soils.

Key messages
  • To develop a better diagnostic index, soils from a series of field and glasshouse copper trials were extracted using 6 different solutions.
  •  Ammonium bicarbonate plus EDTA extract copper was significantly correlated with dry matter production but not relative grain yield.
  • A more meaningful correlation was found when non copper responsive sites were removed from the analysis.
