Irrigating Agriculture

The design of a Centre Pivot or Lateral Move irrigator

System design can vary greatly for Centre Pivot or Lateral Move (CPLM) irrigation systems. Variations in design can have a large effect on capital and operating costs. Paddock shape, soil type, local climate, crops to be grown and power source will all influence design requirements. Understanding these design requirements for […]

Planning a Centre Pivot or Lateral Move system

When planning a Centre Pivot or Lateral Move (CPLM) system the following aspects need to be considered at the planning stage:

Physical location (area, shape, topography, soil type)
Water supply (flow rate, supply location, quality and quantity)
Irrigable area (area to be developed, system capacity)

Land area: A typical centre pivot system has a […]

Centre Pivot or Lateral Move – what to consider?

Centre Pivot and Lateral Move (CPLM) irrigation systems have many advantages over surface irrigation systems. However careful consideration regarding system design, as well as adequate system maintenance and management, is essential to achieving these benefits.  The following points need to be considered when installing CPLM systems:
Advantages and disadvantages of […]

Aspects to consider when choosing an irrigation system for horticulture

Irrigation system selection is an important aspect of setting up or upgrading horticultural enterprises. There are many different types of irrigation systems available, and in many cases there is no single best solution for any given situation.
Each irrigation system type has its advantages and disadvantages, depending on the situation, […]

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 […]

Using soil moisture information to schedule irrigations

As part of the Accelerating Change project in Northern Victoria, various soil moisture monitoring (SMM) devices were used over the last 3 years under surface irrigated pasture and other forages on farm to assist with improved irrigation timing.
Key learnings
SMM provides objective and useful information for irrigation scheduling and reduces the […]

Soil Salinity Surveys on offer for North Central irrigators

Winter presents the perfect time for Torrumbarry and Loddon Valley irrigators in the GMID to conduct surveys for soil salinity levels, an important requirement of the Whole Farm Planning process. Surveys can only be undertaken when adequate soil moisture is available. Surveys are available free of charge for eligible irrigators.
Almost […]

No seasonal adjustment to AUL in the Macalister Irrigation District

Lake Glenmaggie

Given the dry irrigation season, many Macalister Irrigation District irrigators have queried why there has been no seasonal district-wide adjustment to Annual Use Limit (AUL).
Annual use limits set a total amount of water that can be applied per hectare and ensure that farm irrigation practices limit the off-farm impacts of […]

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 […]
