There are benefits in aerating irrigation water as it is delivered to root system through subsurface drip irrigation (SDI). It represents a potentially big step towards increasing yields, water use efficiency and grower acceptance of SDI. Irrigated agriculture accounts for about 70% of total water usage (about 40,000 gigalitres in Australia with 13% being used in horticulture and viticulture (HAL 2003)).
