Research shows plantain can reduce nitrogen leaching by 20-60%
The results, from the DairyNZ-led Plantain Potency and Practice (PPP) Programme, prove 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. “These are exciting results – 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,” says DairyNZ chief executive Dr Tim Mackle. “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. “These research findings are part of a broader programme of work to continue delivering on dairy’s commitment to reducing its environmental footprint in our local communities, while maintaining profitable businesses,” says Dr Mackle. The $22 million seven-year PPP Programme is funded by DairyNZ, 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 percent in perennial ryegrass and clover pastures containing 30 to 50 percent Ecotain plantain. The results are compared to traditional perennial ryegrass and clover paddocks (the most common […]
