Journal of the Department of Agriculture, Western Australia, Series 4
Major changes are underway in irrigation practices for the Ord sugar industry as it moves to implement recent findings on improving irrigation efficiency and managing rising groundwater. Significant improvement in efficiency is expected by more accurately matching water application with crop water requirements and by minimising drainage losses through improved water application techniques.
Based on findings from this work, drying off may not be an appropriate strategy for the ORIA as a means of improving crop sucrose content, but could allow for some reduction in water use towards the end of the crop cycle without adversely impacting on sucrose yield. …

Crossings For Channels And Drains In The Ord River Area, K S. Cole
Journal of the Department of Agriculture, Western Australia, Series 4
ON farms irrigated by surface methods it is essential to provide crossings over channels and drains.
These crossings must be wide and strong enough to take the biggest farm machinery.

Swing Fence Flood Crossing For Creeks In The Kimberleys, A L. Payne
Journal of the Department of Agriculture, Western Australia, Series 4
FENCING is the basis of the regeneration programme on the eroded Ord River catchment area, and the fences constructed must cross numerous creeks.
But heavy downpours of short duration characterise the wet season experienced in this area.
Because the rain falls on to bare, compacted ground, run-off is intense and gullies and creeks rise rapidly, causing serious damage to conventional fences and flood gates across watercourses.

THE best way to grow dry season crops of safflower, linseed and rapeseed under irrigation in the Ord Valley is by sowing on to broad flat ridges, separated by small furrows 3 ft. 6 in. apart.
This system of sowing is called the "corrugation" method.
