Irrigation systems, in particular drip irrigation, will only operate properly if well maintained. By regularly monitoring and maintaining its components we can reduce blockages, deterioration of drippers, pressure irregularities, and impacts on tree health and yields. Here we highlight some management techniques that will help irrigators to retain maximum benefits [...]
Filtration is an essential component of some irrigation methods and a crucial part of drip irrigation systems. Besides being an expensive investment at first, it pays off by: Reducing debris and other contaminates entering the system. Avoiding blockages. Extending the life of the system. Lowering labour costs and work time. [...]
Fertigation is the application of soluble fertilisers and micronutrients to crops through an irrigation system, and drip irrigation systems are highly suited to support this process, generally used to supply the crop's nitrogen, phosphorus, potassium, calcium, and magnesium needs. Advantages Disadvantages - Less volatilisation as fertiliser is applied directly to [...]
There are two basic injection methods used to apply fertigation in drip irrigation systems: pressure differential and injection pumps. Many factors will influence which system suits your needs best and can be dependent on your management style, skill level, farm size, layout, costs, power supply, or crop sensitivity. In this [...]
Drip irrigation systems use small-diameter tubes placed above or below the soil's surface. These systems are generally used in orchards, vineyards, or high-valued vegetable crops. Here we are going to highlight some aspects to consider when planning a drip irrigation system. Water quality Regardless of the irrigation method, all irrigators [...]
Irrigation systems only operate well if properly maintained. This is especially important for drip irrigation, as it is difficult to detect problems before crop health problems become obvious. The most common problems with drip irrigation are: emitter clogging dripper component deterioration system pressure mismanagement. Regular maintenance and monitoring is the [...]
Agriculture Victoria is running a one-day workshop for irrigators. Get the latest information on drip irrigation system design, operation and maintenance. Topics covered include: System specifications – understanding designs and specification sheets. System monitoring – measuring pressures and discharge. System maintenance – flushing, chlorination, and acid injection. The course will [...]
In recent years, water availability has been a key issue for many horticultural crops. The Apple and Pear Australia Ltd, APAL, recently hosted a webinar on options for orchard management through drought. Mark Skewes, Research Scientist at SARDI, shared his research on farm monitoring in irrigated citrus, almonds, avocado and [...]
Improving water use efficiency and maintaining best practice management is a priority for most irrigators. Hort Innovation, using the almond research and development levy and contributions from the Australian Government, funded a project to determine best practice management for Almond irrigation and equip growers with tools to improve water use [...]
System drainage, or drainout is an issue faced by drip irrigators. It can cause uneven water application, restrict vehicle access, disease, environmental impacts and crop productivity loss. Drainage occurs after every irrigation event when water in the submains and laterals run to the lowest point in the orchard or vineyard. [...]
