- •
Treated wastewater (TWW) irrigation effects on a 4.5 m profile of a clay soil were tested.
- •
TWW irrigation had insignificant effects on basic soil properties including sodicity.
- •
TWW irrigation caused a reduction in the saturated hydraulic conductivity (HC).
- •
TWW irrigation adversely affected unsaturated HC at matric potential ≳− 100 cm (pF ≲ 2).
