Contributor The University of Adelaide
Trial location(s) Goolagong, NSW
Managing secondary or trace nutrients in the current cropping environment locations
Aims

To investigate the economical viability of trace nutrient (Zn) application.

Key messages
  • With high grain prices, small increases in productivity can significantly improve farm profitability.
  • A balanced crop nutrition program is extremely important to optimise crop yields. 
  • At Goolagong, NSW, wheat yields were significantly increased by the use of a balanced fertiliser regime including N, P, K, S, Mg and Zn.
  • An analysis of gross margins showed that the application of secondary and trace elements would have significantly improved farm profitability.
