Management of soil acidity in agricultural land - Agriculture Western Australia.
Soil acidity is a sleeping monster.
It helps increase the spread of salinity by decreasing the water use of agricultural plants. This damages the root structure and changes nutrient availability. Many light textured soils in Western Australia's cropping areas were slightly acid before they were cleared. Fertiliser Use Leaching of nitrogen is acidifying, regardless of whether the nitrogen is from legumes or fertilisers. Non-ammonium based fertilisers, such as urea only cause soil acidification if the nitrate they are converted to is leached from the root zone.
