Oxygation

Oxygation involves mixing atmospheric air with irrigation water using a venturi and delivering it via a surface or subsurface drip irrigation system.

Increasing competition on supply of fresh water for irrigation by agricultural, domestic, sports and industrial users demands water use efficient irrigation methods and compliance with environmental regulations.

Guidelines for Fertigating Citrus

This fact sheet outlines the approaches to fertigation, equipment used and links to more information on citrus fertigation.

Vital Role For Australian Irrigation - 2012

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)...

Knowledge and tools to manage fertigation technologies

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.

Guidelines for Fertigating Citrus Orchards

Managing fertigation systems to achieve good productivity and avoiding fertiliser wastage and loss.

Soil management for Australian irrigated horticulture

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.

Soil Management for Australian Irrigated Agriculture - Stonefruit

This case study looks at the project: Soil Management for Australian Irrigated Agriculture. The project addressed what was seen as the main cause for low productivity: “Australian soils rapidly deteriorate when put under crops – they go hard, then restrict crop roots, yield falls off disastrously and the crops become uneconomic after two years. Soil improvement trials were undertaken on-farm as part of the project.

Soil Management for Australian Irrigated Agriculture - Orchard Yields

This case study looks at improving soil preparation and management to increase orchard yields.

Sustaining perennial horticultural production

This publication explores ongoing perennial horticultural production using supplementary irrigation with saline groundwater. The role of rainfall, spatial distribution of salinity and salt-exclusion characteristics of rootstocks are among the considerations.

Managing fertigation technologies in citrus orchards

With recent advances in technology irrigators can now more precisely control delivery of mineral nutrients and water to the roots of perennial tree crops. These technologies, collectively referred to as fertigation, provide the opportunity to adopt and implement highly technical management programs, such as open hydroponics, that use drip irrigation to deliver a balanced mixture of nutrients and water. This research bulletin provides an overview of a project, (more)...
