Some occurrences of manganese toxicity in New South Wales locations
Aims

To provide a brief review of manganese toxicity in New South Wales.

Key messages
  • Manganese toxicity developed on acid red basaltic soils north coast of New South Wales following continued use of ammonium sulphate fertiliser French beans.
  • This was likely due to acidification of the soil as when pH fell below 4.5 large amounts of available manganese were released.
  • Line at 5 to 7 tons per hectare alleviated the problem.
  • Difficulty in establishing pastures, especially lucerne, in the Albury district shown to be a result of manganese toxicity.
  • Liming at 2 tons per hectare increased soil pH and lowered manganese concentrations in leaves and in soil but did not reduce soil manganese below toxic concentrations in waterlogged and heat exposed soils.
