WebNitrogen Fixation. Nitrogen fixation is the process by which gaseous nitrogen is converted to NH3 or NH4+ through biological fixation, or NO3− through high energy physical processes (for example lightning, volcanic action and combustion). From: Reference Module in Earth Systems and Environmental Sciences, 2024. WebThe results from the different countries showed that dry conditions and high temperatures contribute to low levels of fixation. Similar to other published results this study provides evidence for substantial genotype variability. The high values for nitrogen fixation were observed on adapted cultivars and breeding lines when the environmental
