Abstract
In New Zealand the use of nitrogen fertiliser has in past 25 years increased 600% while dairy production, where much of the nitrogen fertiliser is used, has increased by 270%. The unintended consequences of the excessive use of nitrogen have been a cost to the overall environment.
A paradigm shift is needed to achieve sustainable farming systems. Much of the science to support this shift has been published and it is time to dust off these research papers re-educate and share the established knowledge with industry leaders taking responsibility.
Sustainability is a journey. It is about the People, the Planet and Profit. Practices must change to ensure they meet today’s needs while ensuring future generations have the ability to meet their needs.
