The Value of Nitrogen Fertiliser
In 2019, the Fertiliser Association of New Zealand commissioned a study to analyse the costs to the primary sector both associated with removing nitrogen fertiliser or using a substitute. For pastoral farms, this included use of supplementary feed to replace grass grown with nitrogen fertiliser. The research findings demonstrated that not using nitrogen fertiliser would result in a drop of $19.8 billion gross output to the New Zealand economy and a drop in GDP of $6.7 billion.
The report findings have been summarised in a downloadable infographic.
