Oxygation involves mixing atmospheric air with irrigation water using a venturi and delivering it via a surface or subsurface drip irrigation (SDI) system.
Oxygation as a tool delivers air into the crop root zone. Oxygen limitations can be significant in compacted, saline, and water logged soil, and with high BOD effluent irrigation water.
Thi fact sheet summarises Australia’s role in global irrigated food production.
Australia’s irrigators have a vital role to play in meeting the challenge of global food security in the context of climate change and a growing global population. With population growth and standards of living and diet increasing in some regions, the demand for food will double in coming decades. Irrigation currently provides 40% of world food supplies and is projected to meet 60% (more)...
This fact sheet summarises the use of irrigation in Australia.
Irrigation occupies a very small portion of Australia – 5% of tilled agricultural lands – but produces 30% of all agricultural production.
Agriculture uses 50-70% of the water consumed in Australia per annum and irrigation uses 90% of that. The vast majority of irrigated water use is controlled by regulations and
licences. Irrigators need an authorised allocation to extract specified (more)...
in highly productive citrus orchards for minimal environmental footprint
This project aimed to address knowledge gaps and test assumptions regarding the application of modern approaches to the delivery of water and dissolved mineral fertilisers to citrus trees under Australian conditions.
Irrigators will introduce new technologies but the pace of this depends on personal circumstances, including finances, their business development aspirations and the need to test and adapt to suit operations.
Irrigation farming has changed significantly in the past 25 years. Policy and climatic changes have seen the amount of water available to irrigators reduced which has driven greater water use efficiency at both farm and regional levels.
Research recently completed by CSIRO Ecosystem Sciences aimed to identify likely changes to irrigation practices, the potential implications for native biodiversity in irrigation landscapes, and (more)...
A major investment in research into improved methods of applying water and nutrients to citrus has resulted in an important contribution to the science in this area as well as techniques that can be applied by growers to improve their operations.
Presented in this report is a new system of orchard soil management that overcomes coalescence. Iit involves planting of rye grass, which produces rhizosheaths of soil around each of its roots to aid development of properties found in the world’s best soils.
This report looks at the experiences from farming systems that used experimental and participatory modelling methods to explore farmer’s opportunities to develop more profitable and less risky irrigated cotton, grains and rice-grains farm businesses.
