    Abstract

    A study was conducted to examine the changes in soil chemical and physical properties. Testing of the soil chemical and physical properties was conducted on a seven-year old SDI system, laid in Wunnamurra Clay soil in the MIA. The site was planted with processing tomatoes, rockmelons and onions on permanent beds spaced at 1.8m. The preliminary investigations showed a change through the bed in soil colour but not in bulk density. This study has determined changes in clay content, cation levels and the pore space around emitters as a result of SDI. These changes could have inhibited the movement of water by altering soil hydraulic properties and reducing the spread of the irrigation wetting-front.
