National Program for Sustainable Irrigation

Long term sustainability of precision irrigation (UAD25)

Principal InvestigatorDr Cameron Grant Dr Robert Murray
HostOrganisationUniversity of Adelaide
Issue Being AddressedTo investigate soil structure decline and associated yield reduction under irrigated crops.
ObjectivesTo assess the extent of precision irrigation-induced soil degradation on texture-contrast soils of the Barossa Valley.
To establish the roles of soil type, irrigation water quality, amount of applied precision irrigation and methods of application of precision irrigation (e.g. pulse versus continuous) in soil degradation.
To quantify the vulnerability of soils, in combination with various water qualities, to degradation under precision irrigation using a 'hazard rating'.
To develop and test management strategies to minimize and reverse soil degradation under precision irrigation.
To prepare, with LWA editorial and publishing support, a grower-friendly guideline on
a.best management practices for the industries using precision irrigation to reduce irrigation induced soil structure decline.
b.identification of any trade-offs between best management practices for soil structure, nutrients, pesticides and root zone salinity.
To provide technical support to a separate project team charged with interpreting the projects findings for other climatic zones and commodities.
To communicate new findings and additional outcomes to policy makers (SA, Vic, NSW, MDBC, NWC).
