OSPRI writes off $17m over botched traceability system
Animal disease management agency OSPRI has written off nearly $17 million after a botched attempt to launch a new integrated animal disease management and traceability system.
Results from the DairyNZ-led Plantain Potency and Practice (PPP) Programme, unveiled last week, show that using Ecotain plantain in pasture can significantly reduce nitrogen entering waterways.
Farm trials at Massey University and initial results from a trial at Lincoln University are showing similar trends.
The trials are part of the nationwide PPP research and development programme that partners with dairy farmers, industry and government.
DairyNZ chief executive Dr Tim Mackle describes the results as “exciting”.
“We now have robust scientific evidence that Ecotain plantain is an effective solution to help dairy farmers further reduce farm footprint and continue playing their part in improving water quality,” Mackle says.
“Plantain can bring significant benefits to local waterways and communities – we all want healthy freshwater to swim and play in, and dairy farmers can confidently use Ecotain plantain on-farm to support that.”
The $22 million seven-year PPP Programme is funded by DairyNZ, by the Government through the Ministry for Primary Industries’ Sustainable Food and Fibre Futures fund, PGG Wrightson Seeds and Fonterra, working with six additional research and delivery partners.
The programme uses Ecotain environmental plantain from Agricom because it has proven effectiveness. An evaluation system is available to assess the environmental benefits of all plantain cultivars sold by a range of providers.
At the Massey University farm trial, scientists are measuring nitrogen leaching from paddocks grazed by 80 dairy cows. After two years, the trial results have shown reduced nitrogen leaching by 20 to 60% in perennial ryegrass and clover pastures containing 30 to 50% Ecotain plantain.
The results are compared to traditional perennial ryegrass and clover paddocks (the most common pasture types in New Zealand). There was no difference in milk production between the plantain and control pastures in the trial.
The amount of reduced nitrogen leaching depends on the quantity of plantain in the pasture, the soil type, climate and farm system. The Massey University trial will continue for a further two years.
Initial results from the programme’s Lincoln University study in Canterbury, on lighter soils under irrigation, show similar trends to the Massey University trial, with a 38-50% reduction in nitrogen leaching from pasture containing 24% Ecotain plantain. More data is being collected to confirm these results.
Massey University’s Peter Kemp and his team have been researching the effects of plantain over several years and the experimental plots were established at the university in 2019.
“The four-year trial has had incredible success so far and our trial site allows the results to be directly transferable to current farming systems in New Zealand,” he says.
“Importantly for farmers, transition to plantain pastures results in no loss of production, while simultaneously reducing nitrogen leaching significantly from farms into freshwater.”
