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
The rate of soil acidification due to agriculture can be reduced but not eliminated. Liming will always be needed to prevent the soil from becoming too acidic.
Soil acidity is a major constraint to farming in Western Australia.
