The use of slant-path FTIR techniques to measure gaseous N loss in Australian dryland wheat following urea/urease inhibitors fertilizers application

Abstract

Nitrogen losses following fertilizer application not only cause nutrient loss to the crops, but also have negative environmental impacts, including ammonia (NH3) and greenhouse gas emissions (GHG) (e.g., nitrous oxide, N2O). Numerous studies have been carried out to investigate the efficiency of fertilizer use, aiming to increase crop yield and reduce environmental impacts including GHG and other gaseous emissions. There are different measurement approaches of quantifying gaseous nitrogen (N) losses, and static chamber methods are the most commonly used approach for directly measuring emissions from soils. However, chambers interfere with the soil environment, the small measurement footprint..
