Kirra Plains: comparison of tillage methods for lime incorporation: Year 2 locations
Aims

To showcase to growers different methods for deep incorporation of lime to ameliorate sub surface, below 10cm, acidity and improve soil health.

Key messages
  • 2015 - Plots with-out lime were consistently lower yeilding than plots with lime irrespective of incorporation treatment. Threatments with incorporation tended to have higher yield than where lime is left on the surface.
  • 2014 - sowing setup remains the weakest link when using deep tillage. Depth of sowing is critical and fifficult to control on ameliorated soils. A good establishment density is critcal for reducing erosion potential at both ends of the season.
