✓ Soils are mainly saline-sodic (saline-alkali) with an over-accumulation of Na+ and soluble salts, contributing to soil disaggregation,

water-logging, transient salinity and plant toxicity

✓ The salt-term classification (USDA) should consider salt types and their ratios for a more suitable salt-affected soil characterization

✓ The regression models for SARe, EC1:5, and ESP can be used to estimate ESP, ECe and CROSS respectively

✓ Due to dominant salinity and sodicity, chemical/organic amendments and lixiviation strategies for saline-sodic soil

reclamation might be assessed

• Generate a comprehensive salt-term soil classification, besides

a salt-affected soil description database

• Validate the relationships among salinity / sodicity parameters

• Define future perspectives in terms of soil rehabilitation

- Exchangeable Na+ and

EC show similar behavior

- Taking into account

[2CO3= + HCO3-] and/or

Na+ over [Cl- + 2SO4=]

ratios (Chhabra 2005),

neutral salts predominate

over alkaline salts

- Predicted ESP from SARe

correlates to ESP of

exchangeable cations

- High correlation

between Ece and EC1:5

- “Saline-sodic” is the

prevalent salinity class*

*According USDA classification
