A quick guide to the use of the cloud-based IrriSAT app
This case study explains how the irrigation tool, IrriSAT, combined with soil moisture monitoring, provided important information to the grower about crop water requirements and actual soil moisture levels. This enabled him to manage his crop irrigation to maximise yield and quality.
This NSW case study has shown that IrriSAT satellite images, used to monitor irrigation, can also help potato growers identify soil and irrigation problems across the pivot. Fixing the problems identified in this case study would have increased yield and revenue by between $7,600 and $10,800 under this half pivot.
A new series of ‘Sustainable Success Stories’ from the South Australian vegetable industry showcase how local leaders are engaging with industry-led programs to overcome farm challenges and improve their sustainability. Take a look at the five case studies below.
In this edition: Get effective R&D support in a remote setting, demonstration site news from Victoria and Bathurst, NSW, and new resources on managing salinity in potato and vegetable production.
In this edition: Have your say on agvet chemicals review, demonstration site news from Bathurst, NSW and Tasmania, and new resources on nutrition management support.
Practical use of IrriSAT satellite imaging, weather data, and soil moisture sensors.
Irrigation decision making is one of the most significant factors affecting potato yield and quality. Join Dr. Kelvin Montagu and Marc Hinderager from the Soil Wealth / ICP project team discuss the new approaches to managing potato irrigation.
Learn about using the IrriSAT technology which combines evapotranspiration (ETo) and satellite imaging, and how to link this with data from direct soil moisture sensors, to help you schedule irrigation.
Marc and Kelvin discuss a recent case study conducted near Cowra, NSW to illustrate how the methods can work for potatoes.
Tasmanian leafy salad growing operation Harvest Farms is taking part in a trial with SWAN systems, an irrigation and crop nutrition management software platform, to achieve greater efficiency across the farm's 85 irrigation zones. The company grows a variety of salad crops on 65 hectares under fixed sprinkler irrigation.
This article from Good Fruit and Vegetables provides an overview of the trial and initial results.
Irrigation and water management remains of paramount importance, as the Bureau of Meteorology is forecasting a drier and hotter than average remainder of summer. This comes after the dry year 2019 with some vegetable growing regions receiving less than half of their usual rainfall (see figure below).
The Soil Wealth/ICP team have set up a new demonstration site at Cowra to demonstrate the benefits of new tools to improve water use efficiency in potatoes.
As crop growth and water use increase with the warmer weather, it’s a good time to think about getting on top of irrigation management and reviewing your water availability.
Watch this webinar, hosted by VegNET, for a Victoria specific focus on the summer weather outlook, water availability north of the divide and preparation of irrigation systems.
Greenhouse cucumbers can be one of the most productive of all crops. However, this productivity relies on accurate control of irrigation, plant nutrition and the growing environment, as well as effective management of pests and diseases. Only healthy plants can produce a high quality, marketable and profitable crop.
This manual provides basic guidance on growing greenhouse cucumbers. The focus is on modern, controlled environment production. However, much of the included information is relevant to all cucumber growers and, indeed, greenhouse producers more generally.
Knowing how wet or dry your subsoil moisture will help make decisions around when to start or increase irrigation, when to terminate cover crops, and how much "insurance water" you have in your soil.
Crop water use can increase by more than 400% in spring - early summer due to rapid crop growth combined with increases in seasonal water demand (ETo). Be prepared for the increase in irrigation demand.
Make sure your crop monitoring and soil moisture tools are working before it really warms up and crops really get going.
Understanding Irrigation Decisions has been written to put in content and provide guidance on irrigation decisions ranging from enterprise planning to the paddock. To understand the breadth of irrigation decisions requires consideration of the social, financial, agronomic and engineering aspects – a challenging task. Understanding Irrigation Decisions has combined this breadth into one document.
A check of your irrigation system will ensure you are ready to start irrigating on time and are set-up well for the season ahead.
This checklist, while developed for K-Line systems, is applicable to most irrigation systems used in vegetable production. Use it as a guide to your irrigation system check.
When irrigating vegetable crops, the use of poor water quality can affect both the crop and soil in which the plants are growing.
Water analysis is a valuable tool for determining potential or existing salinity problems, developing irrigation strategies, and verifying toxicities or mineral imbalances.
This fact sheet covers the water quality parameters you should know about, like salinity, sodicity, calcium carbonate and other macronutrients.
Recycled water is used in nearly all Australian states for vegetable production. Recycled water irrigation schemes offer a number of benefits.
Need to know more about irrigating with recycled water? Then check out this fact sheet that provides a practical overview on the guidelines for recycled water, potential issues, nutrients and further information.
The series, produced by Greater Sydney Local Land Services, Applied Horticultural Research and VegNET NSW helps growers explore how to implement protected cropping on their growing operations.
Using water efficiently means applying enough water to meet the needs of the crop - not more, not less.
A soil in good condition consists of around 50% solid matter; this includes organic matter. The remaining space should be half filled with air and half with water. Organic matter is the main driver of soil health.
Read this practical fact sheet for guidance on readily available water (RAW) and soil texture, as well as healthy soil conditions.
Sweet corn has a high water requirement. The most sensitive growth stages (3–5) are also when crop water usage is at its highest, increasing by more than 400% over a few weeks. This rapid increase in crop water use can catch growers out and reduce yield and quality.
Read this fact sheet to discover more about practical irrigation tips including crop development, water use and key irrigation decisions, as well as handy tools available to help with irrigation decisions. Guidance on soil moisture monitoring is also provided.
