New Research Shows Good Farming Practices Reducing Nutrient Losses on Dairy Farms
Analysis of decades of research has revealed the good farming pracrtice plays a critical role in reducing nutrient losses to improve freshwater outcomes.
DairyNZ chief executive Tim Mackle says the on-farm fencing requirements in the new rules have already been met by 97.1% of dairy farmers around the country, and the target by May, a month ahead of the new requirements, is to be 100%, with all waterways running through dairy farms will be fenced off and all stock crossings bridged.
“This means that right now very few dairy cattle have any access to waterways, and in just two months’ time no dairy cattle – that’s zero dairy cattle – should have access to waterways on our farms.”
The Government’s plan includes setting a target for 90% of rivers and lakes to be swimmable by 2040 and 56,000 km of more fences to protect waterways from stock...
Mackle says fencing – currently 27,109 kms – is always set back a healthy distance from waterways, varying from farm to farm depending on the soil type and contour of the land.
“This ensures the optimum levels of bacteria, nutrients and sediment are filtered. Farmers also keep cows off sensitive areas in the vicinity of the fenced waterways, for example, in wet weather.”
“There’s still a way to go in some areas, and dairy farmers are well aware of that. We acknowledge that improving New Zealand waterways is a long journey, as today’s announcement recognises. The good news is dairy farmers around the country are leading the way in protecting freshwater on their farms.
“Our dairy farmers can be immensely proud of the work they are undertaking for the environment on their farms, and many are also doing work to improve their surrounding communities – and all New Zealanders, whether they are living in towns and cities, or in rural communities, can also be proud of the efforts of our dairy farmers,” says Mackle.
As part of their commitment to the environment, dairy farmers are also planting vegetation along waterways, and using native plants such as manuka, cabbage trees and flaxes, as well as native grasses, that have superior ability to filter and slow run-off, he says.
“Added to this, all dairy farms now have dedicated effluent management systems with effluent ponds, just like towns around the country. Areas such as the dairy shed and yards drain directly into these systems where the effluent is stored and later used by farmers to fertilise their land.
“It’s also encouraging to see the rates of dairy effluent related prosecutions and abatement notices continuing to decline dramatically, and an improvement in overall effluent non-compliance, which is the lowest it has been in recent years.”
Over the past three years farmers have invested over $1 billion dollars in environmental protection measures, he says.
