Dry weather drives smart irrigation in the United Kingdom

The Environment Agency (EA) in the United Kingdom has already declared irrigation prospects ‘moderate to poor’ in the East of England – in Cambridgeshire, Suffolk, Norfolk and Essex – areas reliant upon chalk aquafers for supply.

Many other areas are also classified as ‘moderate’, with much of England in a weaker position than 2018.

Acting to help, Agriculture and Horticulture Development Board is calling the industry to consider options to place them in a stronger position for the summer.

Nicola Dunn, Water Resources Scientist at AHDB:

“With time to prepare, we’d encourage farmers and growers to develop contingency plans and consider options, which could make the difference between a profit or loss situation this summer.”

“Throughout winter and spring, the EA has issued certain areas with ‘hands off flow’ notices, meaning farmers and growers must stop abstracting water to top up storage facilities. This means later in the year, savvy techniques will be needed to help businesses get more from the water they have in the worst affected areas.”

“If your business has water storage facilities which are fully topped up, you could approach the EA to find out if you could trade water with a neighbour.”

“Exploring investment into techniques like precision irrigation could reduce the volume of water needed through the season. And, in the longer term if you’re planting crops, there may be more resilient varieties you could choose where the market dictates, which manage better in dry conditions.”

David Hoyles, Lincolnshire farmer and Chairman of Nene Potatoes speaking on the AHDB Podcast:

“We grow a variety of root crops, peas and some cereals on farm. Last year we prioritised our irrigation focusing on our most profitable crops first, as a result our potatoes and beetroot yields turned out well. However, our sugar beet crop, which was not irrigated, delivered a yield almost 25 per cent less than we achieved in 2017.”

“This year is looking like a bigger challenge than last, because our reservoir is currently at 30 per cent. We’re already irrigating, but to help us manage and target our water use we’ve invested in more soil moisture probes, we’re also getting out with a spade to check ground conditions.”

“A learning from last year was that we need better crop nutrition, so we’ve also been looking at different ways to do that, with bio-stimulant trials underway we’re following the ADAS guidance and taking samples from our crops as we go. The good thing is, we have time to prepare and we’re acting early to make sure we’re better protected.”
