Fertiliser company Ravensdown says it will be supporting appeals challenging Environment Court rulings on the much debated Manawatu-Whanganui regional plan.
The Environment Court rejected appeals against Horizons Regional Council's One Plan, which breaks new ground in the way it proposes to set controls on nutrient run-off and leaching from farming and horticulture operations to protect water ways.
Its ruling means that all intensive farming and horticulture operations will need nutrient management plans and consents.
Federated Farmers and Horticulture New Zealand have lodged appeals in the High Court.
Ravensdown chief executive Rodney Green says the fertiliser co-operative also has concerns about the plan and court rulings.
"We had quite some concerns about it .. we are certainly looking to support that appeal," he says.
But the company did not shy away from the fact that nutrient applications had to be managed.
"The farmers have - to a very large extent - embraced that ... you're seeing a very large change in farming because of that," says Mr Green.
