Should we measure easily reducible manganese? locations
Aims

To examine which soil analysis to use for manganese.

Key messages
  • Acid soils from southern New South Wales were analysed for manganese.
  • Manganese was measured using ammonium acetate, ammonium acetate with hydroquinone or on a barium chloride leachate.
  • There was no relationship between exchangeable and easily reducible manganese ( ammonium acetate plus hydroquinone extractable).
  • As easily reducible manganese relates most closely to plant available it is suggested that manganese be measured on ammonium acetate plus hydroquinone extracts.
