Trial details

Researcher(s) David Scholz (Elders Ltd)
Year(s) 2003
Contributor Liebe Group
Trial location(s) East Maya, WA
Soil health satelitte site, East Maya locations
Aims

To establish if the current wheat yield could reach potential yield by extra N fertilisation and to identify potential constraints of 8 Satellite Sites throughout the Liebe area

Key messages
  • Basal yield reached 75% of potential yield at this site.
  • The plus N treatment did not significantly affect yield, and N was not a limiting factor.
  • Moisture was in excess below 60cm soil depth.
