Sodic soils are widespread in Australia reflecting the predominance of sodium chloride in groundwaters and soil solutions. Sodic soils are subject to severe structural degradation and restrict plant performance through poor soil-water and soil-air relations.

This paper gives a broad overview of the distribution and agricultural importance of sodic soils in Victoria. Sodic soils are estimated to occupy at least 13.4 Mha, representing at least 73% of Victoria's agricultural land. Most of this land is used for dryland farming; about 85% of the cropped land and 66% of the land sown to dryland pastures occurs ...

The objective in reclaiming sodic soils is to ameliorate undesirable physical conditions such as surface crusting and low hydraulic conductivity which impede infiltration, water storage, seedling emergence and root development. These undesirable physical characteristics result from enhancement, by exchangeable sodium, of clay swelling, dispersion, and ...

Tatura Sodicity Conference: knowledge gaps in sodicity research for major agricultural industries
Australian Journal of Experimental Agriculture, 2002This paper summarises the outcomes of the International Sodicity Conference, ‘Sodicity Issues in Agricultural Industries — Current Research and Future Directions’, held at Tatura, Victoria, 28 February–1 March 2000. In this paper we present (i) sodicity issues generic across agricultural industries, (ii) results of the interactive workshop, and (iii ...

Sodic soil reclamation generally involves the application and incorporation of gypsum into the soil followed by leaching. The rate of reclamation depends on the water intake rate. This rate can become very slow due to inadequate electrolyte concentration in the soil solution to counteract the effects of exchangeable sodium on aggregate stability, clay ...

Sodic soils - New perspectives
Australian Journal of Soil Research, 1993There are large areas of the world where soils are adversely affected by the presence of sodium (Na) as an exchangeable cation. Unlike their saline counterparts which are more extensive, sodic soils have received less attention in the literature. There has been considerable disagreement concerning the definition of sodicity, owing largely to the fact ...

According to different estimates, there are 831 to 932 million hectares of salt affected soils – saline soils, saline-sodic soils and sodic soils. The measure of salinity is the electrical conductivity of the saturation extract (ECe) and the measure of sodicity is the exchangeable sodium percentage (ESP) or the sodium adsorption ratio (SAR).
