Root Intrusion in Subsurface Drip Irrigation


In 2009 a sub-surface drip irrigation system utilising KISSS Flat geotextile covering was installed in a number of blocks at Accolade Wines’ Banrock Station vineyard near Kingston-on-Murray in South Australia. This system very quickly suffered major root intrusion, resulting in dripper blockages, resulting in poor application uniformity and patchy vine growth.
In response, a trial was established to document and investigate flow reductions in a subsurface drip irrigation system due to root intrusion.
