Effect of copper and zinc on wheat on newly cleared grey and grey brown gravelly sand  of the central wheatbelt locations

To determine the rates of copper and zinc required for maximum grain yield of wheat grown on greyand brown  gravelly sand

Key messages
  • Cu increased with Zn or without Zn added to superphosphate.  
  • All Zn levels may have aslight depression on yield with nil Cu 2.75 & 5.5 Cu levels, particularly 3.3 kg /ha of ZnO application.
  • Combination of Cu Sul at 5.5 kg/ha and nil  kg/ha ZnO or 8.25 kg Cu/ha& 1.6 kg/ha ZnO was required for maximum yield.
  • Plain superphosphate out yielded  Aerophos +gypsum suggested  Zn soil was inadequat for oats and or clover.
