Soil Water Infiltration and Retention Under Saline and Sodic Conditions.

Worldwide, plant growth and development in arid and semi-arid regions are negatively affected by salinity and sodicity. Describing water infiltration and retention of saline and sodic soils are useful to predict water availability for plants growing under such conditions. In this study, we measured soil hydraulic conductivity and water retention curves of soils variously affected by sodicity, salinity and sodicity-salinity combined under greenhouse conditions. The impact of modified water availability of affected soils to leaf gas exchange and growth of tomato is also discussed.
