Ammonia Volatilization – Field Measurement
Quantify ammonia emissions after spreading with the VOLAT'NH3 method
The Volat’NH3 method developed by INRAE teams can be used in the field to quantify and compare nitrogen flux generated by cultivation practices or fertilizing products. As part of the development of new products or new input methods, it is used to identify practices and products that minimize nitrogen losses and to quantify their impact on air quality.
- Carry out a trial on an agricultural site or in experimental plots
- Measuring nitrogen losses in cropping systems
- Optimize the efficiency of your agricultural practices
Field monitoring coupled with agroclimatic modelling
Based on ammonia concentrations measured using specific sensors and meteorological data acquired from weather stations positioned on the trials, the FIDES model (Flux Interpretation by Dispersion and Exchange over the Short-range, Loubet et al. 2018) is used to obtain ammonia emission flux records and thus arrive at quantities of volatilized nitrogen (in kgN/ha and in % of nitrogen applied).
