BS ISO 20951:2019

This standard BS ISO 20951:2019 Soil Quality. Guidance on methods for measuring greenhouse gases (CO 2, N2 O, CH 4) and ammonia (NH3) fluxes between soils and the atmosphere is classified in these ICS categories:

• 13.020.40 Pollution, pollution control and conservation
• 13.080.01 Soil quality and pedology in general

This document gives an overview and provides guidance on the main methods available to quantify the exchanges of greenhouse gases (CO₂, N₂O, CH₄) and ammonia (NH₃) between soils and the atmosphere.

It is intended to help users to select the measurement method or methods most suited to their purposes by setting out information on the application domain and the main advantages and limitations of each methods.
