Abstract

To investigate the long-term effect (13 and 23 years) of wastewater irrigation on soil physical quality indices in Taqanak, Shahrekord, four homogenous fields but with long and different history of treated municipal wastewater application were selected. The changes in conventional soil physical indicators (organic carbon, bulk density, mean diameter of aggregates) as well as retention-curve derived indices: Dexter’s S index, Macro pore porosity (MacPOR), air capacity (AC), plant available water content (PAWC) and relative water capacity (RWC) were investigated in these farms.Irrigation with wastewater significantly increased (p
