Incorporating Lime to depth on duplex Wheatbelt soils locations

The aim of this trial is to quantify the value of lime applications using different incorporation methods and compare the economic and agronomic returns of each. This trial also includes an application of a rapidly acidifying Elemental Sulphur to demonstrate how soils and crops will perform 10-years into the future if no action is taken to maintain pH levels. The trial also aims to analyse the interactions between each incorporation technique and its effects on ameliorating other crop constraints.


The objective is to give growers a greater understanding of different methods of lime incorporation and the most cost-effective practice locally and to extend on these findings with other research being conducted on varying soil types throughout the state, so that growers can make informed decisions for implementing their own liming strategy.

Key messages
  • Lime application rate had the greatest influence on soil pH in the year of application.
  • The highest lime application of 6 t/ha in combination with spading resulted in the greatest increase in pH across the trial, although at depths of 20-30cm and 30-40cm, 2t/ha, 4t/ha and 6t/ha of lime sand produced similar increases in pH.
  • Higher rates of lime application rate did not increase germination, biomass or grain yield of the cereal crops trialed in the experiment.
  • Deep ripping, followed closely by spading, increased grain yield compared to top-dressing in 2020.
