Fonterra expands seaweed trial

Fonterra is working with seaweed company Sea Forest to expand its on-farm trials to quantify the methane reducing the potential of Asparagopsis seaweed.
Fonterra general manager of sustainability APAC Jack Holden says Fonterra’s grass-fed farming model makes the company one of the most carbon-efficient producers of dairy in the world.
“However, we have an aspiration to be net zero by 2050 and are investing in R&D and partnerships to help find a solution to reducing methane emissions,” said Holden.
CSIRO research has shown that Asparagopsis seaweed has the potential to reduce emissions by over 80 per cent in laboratory trials, and while Fonterra understands the reductions will vary out of the lab, all reductions count.
“As with all methane solutions we’re trialling, what we need to find out is whether we can use this supplement in a way that is safe for cows, safe for consumers and to ensure that there is no impact on milk taste or quality,” says Jack Holden.
Over the past two years, 900 dairy cows on a farm in Australia have been fed small amounts of the seaweed supplement and the results have been promising. Fonterra is now expanding the trial across three additional farms to test the supplement’s application at a commercial-scale.
This will include understanding the practicalities of using the seaweed supplement as part of normal farming operations.
“If the trial proves successful, we have agreed with Sea Forest that Fonterra farmers will have first access to the commercial Asparagopsis solution,” said Holden.
Sea Forest CEO and founder Sam Elsom says last year the company bought an additional 30 hectare farm as it increases its production of the seaweed supplement.
