Insights into irrigation system performance

For this article we thought it would be useful to share some insights from the irrigator performance tests we have undertaken this season. All the pivots we’ve tested were potentially very efficient irrigation systems, however, for a number of older machines (+15,000 hours) we are starting to see performance impacts from worn nozzles and regulators […]

Shaping up to be a challenging irrigation season

It has been an extremely dry and warm start to the 2020-21 irrigation season. If the La Niña weather pattern continues as predicted, Canterbury irrigators will need to keep a careful watch on their seasonal allocation limits and make tactical decisions around their irrigation. If you have used over 60% of your allocation by the […]

Are warmer winters the new norm for Canterbury?

So how much warmer is it than normal? Soil temperature is always a great indicator to watch closely during the spring as it is the key trigger for pasture growth and seed germination. At soil temperatures below 6 degrees Celsius there is extremely limited pasture growth and very few crops that will successfully germinate. The […]

Choosing the right sensor technology

For this post we thought it would be useful to talk about choosing the right sensor technology for your farm. The first step is thinking about the long-term solution you require, not just the problem you need to solve today. Do you only need one sensor for compliance purposes or are you likely to expand […]

Understanding Irrigation System Performance Assessment

Believe it or not winter can be the best time for testing irrigation equipment (obviously providing you have a water supply) as the weather is often at its most settled – fine days with no wind! There are different levels of testing being offered by the irrigation industry and you need to know what you […]

Irrigation Season 2019-20 Review

To wrap up the 2019-20 irrigation season we’ve analysed the weather data from the Lincoln and Winchmore climate stations and then estimated how much water an efficient irrigation system would have used. The following table provides a summary of average daily and monthly water use for pasture (Potential Evapotranspiration – PET) alongside monthly rainfall. The […]

More Tips for Autumn Irrigation

The dry summer is turning into a dry autumn with many areas of Canterbury, particularly central and north, receiving very little rainfall since mid-December. Despite the dry, for autumn irrigation you need to closely follow the weather forecast to get your irrigation right as daily plant water use (ET) is much less than at peak. […]

Getting your autumn irrigation right

It’s been a long dry summer with some areas in Canterbury, particularly mid, central and north, receiving very little rainfall since mid-December. Irrigation is a relatively simple task in dry weather, you turn it on, check the flow rate and system pressure are correct on a daily basis (this can be automated) and keep going […]

Are you having trouble keeping up?

Norwester season has arrived! Irrigation is a relatively simple task in hot dry weather, you turn it on, check the flow rate and system pressure are correct on a daily basis (this can be automated) and keep going until the weather forecast provides you certainty significant rainfall is coming. From late November through to mid-December […]

Irrigation season 2019-20 now underway

After a cold and damp start, the 2019-20 irrigation season has finally begun. In the last post we predicted it would be early November before irrigation needed to start-up. This prediction turned out to be on the money. It was informed through running a water budget using Winchmore and Lincoln climate data, 2-day and 10-day […]
