Diagnosis of trace element deficiencies in wheat on Eyre Peninsula South Australia locations
Aims

To establish the need for trace elements on soils of the Eyre Peninsula.

Key messages
  • Twenty replicated factorial experiments conducted 1970-1971.
  • Copper, manganese, zinc, iron, boron and molybdenum applied as foliar sprays at various times.
  • Vegetative growth was less affected by copper deficiency than grain yield.
  • There was a response to copper at 14 of the 20 sites.
  • Response to other trace elements were much less frequent.
  • Copper deficiency occurred on a wide range of soils.
  • Responses to zinc and manganese applications were confined to calcareous soils.
  • Copper concentration in the tops was poorly correlated with yield but a critical concentration of 2.5 ppm was apparent from grain analysis.
  • The relationship between grain copper and copper responsiveness was not influenced by soil type.
