sodicity

Key achievement has been recognition by Government of expertise in salinity and sodicity issues.

Effects of clay minerals and organic matter on sodicity.

Below a metre, sodicity is hard to diagnose, but sometimes shows up as tunnel erosion.

Drainage, sodicity and related problems of vineyard soils.

Land management is difficult when salinity, sodicity, high calcareous content or an excessive depth of sand occurs.

If there is sodicity in the top metre, it may be evident as water logging, increased run-off and surface crusting.

Approximately one-third of the Australian continent is exposed to the deleterious effects of sodicity.

Environmental consequences of soil sodicity.

All the sodium in these salts enter into the river / ground water during their production process or consumption enhancing water sodicity.

Emergence, establishment and seed yield of chickpea (Cicer arietinum) as affected by sodicity.

Key achievement is recognition of expertise in irrigation projects in relation to salinity, sodicity and nutrient relationships.

Sodic soil or soil sodicity may refer to:

Only 6 per cent of the land is arable without irrigation and large areas are naturally affected by salt, sodicity, waterlogging or acidity.

Screening of genotypes for tolerance to salinity, sodicity and waterlogging, singly and in combination.

Soil sodicity refers the soil's content of sodium compared to its content of other cations, such as calcium.

Meanwhile, land productivity is reduced by water and soil erosion, salinity, sodicity, waterlogging, flooding and loss of organic matter.

It is also a measure of the sodicity of soil, as determined from analysis of water extracted from the soil.

Physio-chemical processes in soil (especially in relation to phosphorus, bicarbonate, boron, sodicity and salinity).

USDA follows the adjusted SAR for calculating water sodicity.

A procedure for the determination of soluble boron in soils ranging widely in boron concentrations, sodicity, and pH.

Prepared technical publications on sodicity, salinity and evapotranspiration systems for NSW Department of Local Government.

Certified Agricultural Scientist with specific expertise in soil management in agricultural land use planning, salinity and sodicity issues and fertiliser requirements.

A soil test to measure the pH, Electrical conductivity, Sodicity, Clay content and cations of a clay sample.

Acidity and sodicity (dominance by sodium salts) together result in a decline in soil structure and a breakdown of clays leading to greatly reduced water quality.

Processes of land degradation including salinisation, sodicity and erosion are discussed, as are methods of soil restoration, minesite rehabilitation and soil conservation.
