Trial details

Contributor Liebe Group
Trial location(s) East Carnamah, WA
Measuring the long term effects of liming in wheat locations
Aims

To evaluate the long term effect various rates of lime applications has on yield and protein in wheat.

Key messages
  • Due to the dry start to the season, germination across the trial paddock was very uneven, which may have influenced the yield results of the trial.
  • It is anticipated that further soil sampling and analysis work will be carried out on this trial in 2009 to look at the residual effect of lime on the soil pH and aluminium toxicity.
