DoubleRoot Case Study: Gavin Nichol

Gavin Nichol on boosting pasture production with DoubleRoot: “Paddocks with AberLasting grew another two weeks into the dry.”

Managing the environmental extremes of New Zealand’s Otago region, renowned for its low temperatures and drought conditions, is a significant challenge for sheep and beef farmer Gavin Nichol.

Gavin’s 2,200-hectare property in Clarks Junction – 60 kilometres inland from Dunedin – is situated 500 metres above sea level. Temperatures rarely reach double figures in winter, and long dry periods in summer culminate in an average yearly rainfall of around 500 mm.

AberLasting from our DoubleRoot range is a unique cross of Caucasian clover and white clover and has been part of the farm’s permanent pasture mix since 2014, which is currently planted on 490 hectares. The aim is to provide increased tolerance to weather extremes and boost pasture production for Gavin’s 6,500 ewes and 300 cows.

“The first time AberLasting was planted I was driving down the farm lane and saw that the original pasture was dried off on one side, while the AberLasting paddocks were still white with clover – and both were grazed at the same time,” says Gavin.

“Paddocks with Aberlasting grew another two weeks into the dry.”

Gavin has also seen a marked improvement in lamb weights since using AberLasting alongside red clover varieties.

Touted as the first ‘Super Clover’, DoubleRoot is the world's first successful cross of Caucasian and white clover. It can withstand overnight temperatures of -20 degrees Celsius, which would wipe out 70% of conventional white clover varieties.

In a recent drought tolerance experiment, DoubleRoot maintained leaf water content for one week longer than traditional white clover when completely without water.

Like much of the wider Otago region, the soil pattern of Gavin’s farm is characteristically rocky, which can limit productive capacity. AberLasting is used from the DoubleRoot range as part of a resilient pasture mix that also includes fescue and cocksfoot grasses to help combat such conditions.

The results to date have been promising.
