本文件规定了一项实验室测试，用于表征土壤将温室气体N2O还原为N2的能力（或无能力），因为先前已经表明，将N2O还原为N2能力较低的土壤构成了N2O大量排放风险的情况[6]，高于使用IPCC国家温室气体清单指南[10]中提出的方程在地块尺度上基本估计的情况。该测试在实验室中对以地块比例收集的筛分样品的复合材料进行。除了在非常特殊和极端的干燥条件下，它可以在全年取样的所有类型的土壤上进行。对于既不接受有机物也不接受石灰改良剂的情况，所获得的结果随着时间的推移是稳定的。
This document specifies a laboratory test for characterizing the ability (or inability) of soils to reduce the greenhouse gas N2O into N2 as it was previously shown that soils with a low ability to reduce N2O into N2 constitute situations with a risk of large emission of N2O[6], higher than those basically estimated by the use at the plot scale of the equations proposed in the IPCC guidelines for National Greenhouse Gas Inventories[10].This test is performed in laboratory on a composite of sieved samples collected at the plot scale. It can be performed on all types of soils sampled all over the year except in very exceptional and extreme conditions of dryness. Results obtained are stable over time for situations that do not receive neither organic nor lime amendments.
