Irrigating top tips for the upcoming summer season

Summer is just about here and that means irrigation will become more widespread across North Canterbury. Irrigation can support better growth in paddocks, providing more feed for animals and better conditions for growing crops.

Water is a precious resource in the Waimakariri, Hurunui and Waiau areas – particularly in dry periods like summer.

Waimakariri and Hurunui Waiau zone delivery lead Marco Cataloni said people are strongly encouraged to irrigate efficiently and consider their overall water use.

Over 500,000 hectares of land is irrigated in Canterbury. 

Cataloni said one key factor people should consider when choosing their irrigation system, is its efficiency.

"You should look for one which will maximise the amount of pasture grown while using as little water possible.

"Well-managed irrigation systems protect water quality and quantity, save on pumping costs and protect soil structure, ultimately retaining valuable nutrients."

Irrigation on the road and considering the weather

One key consideration for those irrigating is making sure it stays off the road.

"It’s vital irrigation systems only water within people’s property boundaries and not on the roads where it causes a hazard," Cataloni said.

"The most common reasons for water going over-boundary are the extra spray from end guns on pivot irrigators, and travelling irrigators getting too close to roads," he added.

On hot, windy days, irrigation water drifts on roads, which can contribute to road deterioration and make the hot tar slippery.

"These problems can be easily solved by checking that end guns are set and operating correctly and setting back travelling irrigators an adequate distance from the road," Cataloni said.

Anyone who notices irrigation spray on the road should contact us. If there is an immediate danger to road users, they should contact the police.

Careful placement of irrigators is also needed during Norwest conditions, to ensure irrigators aren’t knocked over.

Irrigation restrictions

Cataloni said it’s important anyone carrying out irrigation ensures they keep up-to-date with the latest restrictions.

"These relate to specific areas, which may relate to the consent you hold. Restrictions are put in place to help reserve water when stock is low," he said.
