Growers in low rainfall areas with predominantly acidic soils have the potential to increase wheat yields by up to 30 per cent by combining lime and gypsum applications to their soils.
The effect of mechanical incorporation of different lime rates on crop yield and subsurface pH was observed four seasons after application.
Mechanical incorporation of different lime rates using offset disc, Grizzly Tiny offsets® and deep ripping treatments were tested.
Amelioration of soil pH in poor soil patches in paddocks was tested using lime application and deep ripping treatments.
Mechanical incorporation of different lime rates using Grizzly Tiny offset® plough, deep ripping and cultivator points were tested.
Management of weeds, disease and nitrogen nutrition are ongoing challenges that limit yield potential.
