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.
If you are deep-ripping, ploughing or spading to remove subsurface compaction or another constraint, it is a good idea to incorporate lime in the same operation.
Using tillage to incorporate lime improves the rates of reaction and increases subsurface pH sooner than spreading lime on the surface alone.
In this section you will find detailed information on various case studies highlighting the long-term benefits of liming and different options used by farmers for incorporating lime.
Agricultural lime is any product that is used to increase the pH of soil. In Western Australia, the three main sources are limesand, limestone and dolomitic lime.
Carbonate from calcium carbonate (or magnesium carbonate) neutralises acid in the soil.
Soil acidification occurs naturally very slowly as soil is weathered, but this process is accelerated by productive agriculture.
