Welcome to More Profit Per Drop
Welcome to our site which has the latest irrigation information and activities for broadacre irrigators in Queensland. It is provided by the Department of Agriculture and Fisheries – Broadacre Farming Systems team who undertake projects to benefit the broadacre irrigation sector. This site is possible through the support of the Healthy HeadWaters Water Use Efficiency project (funded through the Australian Government’s Water for the Future Program).
Field Walk – Improving irrigated mungbean productivity
A field walk is being held at St George on the 23rd March to inspect a trial comparing three mungbean varieties and three different irrigation strategies. Full details of the field walk can be downloaded here
Free Pressure Gauges for Overhead Irrigators in QMDB
A limited number of free end pressure gauges are available for Queensland Murray-Darling Basin (QMDB) irrigators to help them to check the performance of their overhead irrigation systems.
As part of the QMBD Regional Economic Diversification Program (REDP), operators of centre pivot or lateral move irrigation systems are encouraged to complete and submit the form here to register their interest in being sent a free end pressure gauge. DAF senior irrigation research scientist Dr Simon White said the aim was encourage irrigators to check their machines’ performance, to ensure that it is operating within its design specifications and to be aware of any maintenance issues.
“Insufficient end pressure can lead to poor irrigation uniformity and lower profitability, while over pressure can result in inefficient and excessive pumping costs,” Dr White said. “By using a gauge installed on the outermost outlet of the machines, irrigators can check end pressure against the specifications for the machine. By checking the pressure of the machine during its normal operation, you can quickly identify any performance issues and take steps to fix them. To further assist irrigators in the installation and use of the end pressure gauges, simple instructions and a range of pressure stickers will be provided with the gauge.”
Overhead Sprinklers and Irrigation Runoff
One of the issues that occurs with centre pivots is the high application rate of water on the outside spans. This is particularly an issue for the biggest pivots and those on hard-setting soils. The result is increased runoff which can lead to reduced irrigation uniformity and wheel rutting problems. Simon White and Grant Cutler of DAF Queensland staff, have been working with a grower near Texas to evaluate different sprinkler (emitter) types and the use of a fodder crop to improve water infiltration under his centre pivot. This video examines the differences between the different sprinklers and the value of installing a pressure end-gauge on your overhead irrigation system.
