Nutrition management: do soil nutrient levels constrain production in the Victorian high rainfall zone? locations
Aims
  • To see if soil nutrient levels constrain production in the Victorian high rainfall zone.
  • To formulate tools which predict the production, economic response and risk of applying inputs to wheat and canola crops within the south-eastern high rainfall zones.
Key messages
  • The omission (absence) of nitrogen and phosphorus fertiliser inputs at the Inverleigh canola trial site caused a statistically significant reduction in canola grain yield
  • Visual biomass differences at the Glenthompson wheat site were noted during the season, but did not translate to yield
  • Low rainfall and high temperatures in the 2015 spring reduced the response of crops to the presence or absence of nutrients
