Download Refining estimates of nitrogen leaching for the New Zealand agricultural greenhouse gas inventory – Report

This report reviews the suitability of the FracLEACH parameter used to estimate the proportion of nitrogen (N) applied to agricultural land that is lost via leaching and runoff of N. The current inventory methodology employs a uniform FracLEACH of 0.07 of key N inputs, which is used for estimating a proportion of the indirect nitrous oxide emissions from agriculture.
