Zinc bioavailability in wheat grain in relation to phosphorus fertiliser, crop sequence and mycorrhizal fungi locations
Aims

To explore the effects of rotation, P fertiliser and mycorrhizae on wheat grain zinc in rotations.

Key messages
  • Wheat grain Zn concentration decreased with P fertiliser addition.
  • Wheat grain Zn concentration was lower after canola than after either linola or clover pasture.
  • Wheat receiving P fertiliser had lower mycorrhizal colonisation than that with no P added.
  • Wheat after canola had lower mycorrhizal colonisation than that wheat after linola or clover pasture.
  • It was hypothesised that Zn uptake was reduced where mycorrhizal infection was lower.
