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.
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.
In this section you will find answers to commonly asked questions from Western Australian growers and consultants about lime, liming and soil and pH testing, as well as links to other useful inform
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.
Aluminium toxicity in the subsurface is the major problem associated with soil acidity in Western Australia.
A small decrease in soil pH represents a large increase in soil acidity.
Convert to 100% neutralising value (NV) for equal comparison and discount to allow for differences in particle size and speed of reaction.
Liming to recover an acidic soil to an appropriate pH can result in significant production benefits, however a response to liming indicates that previous production has been lost due to an acidic t
