Weekly Irrigation Requirements – Macalister Irrigation District

Macalister ETo Update
3 to 9 January 2019

Flood irrigation interval for the last week was 8 days
Spray irrigators needed to have applied on average 34 mm of irrigation water for the week
The predicted weekly pasture water use for the MID in the next week is 47 mm
Lake Glenmaggie is at 59.5%

Weekly Irrigation Requirements – North East Victoria

Weekly Irrigation Requirements – North East Victoria
This update provides ‘reference evapotranspiration’ (ETo) data to assist with improved irrigation scheduling for top yields and high water productivity.Note: To convert mm to megalitres /ha, divide by 100. Eg. 50mm = 0.5ML /ha

 
What is Potential Evaporanspiration?
Potential evapotranspiration is calculated from a number of other […]

What to know about Evapotranspiration and how to use it to schedule irrigations

Evapotranspiration provides a relatively objective and reliable estimate of the water requirements of actively growing plants in a farm situation. Evapotranspiration information can be used by irrigators to more accurately schedule irrigations to help achieve top yields and improve water productivity.
What is Evapotranspiration?
Evapotranspiration is an estimate of the loss of […]

Variable speed drives — an energy saving option for irrigated horticulture

A variable speed drive (VSD) is used to adjust a pump’s flow or pressure to the field requirements (actual demand). Adopting VSDs in irrigation was historically for operational reasons such as providing constant pressure outputs, ‘soft starts’, or reducing pump wear. More recently, as energy prices continue to rise, the […]

Managing horticultural crops with less water

Irrigators may be faced with reduced water allocations at some stage in the future. In this situation a range of decisions may need to be made including:

       the purchase of additional water (at a likely elevated value);
       prioritise water onto preferred patches;
       giving other patches reduced volumes with consequent reductions […]
