• Closing maize yield gaps in sub-Saharan Africa will boost soil N2O emissions (2020, background): “This exponential increase of soil N2O emissions at the end of the curve most likely occurs because attaining the full water-limited yield potential of maize requires N fertilization rates >100 kg N ha (1), which can lead to excess soil N availability beyond plant N demand, especially if fertilizatio”
• Inventories and scenarios of nitrous oxide emissions (2014, background): “A growing number of studies demonstrate nonlinear (usually exponential) relationships between N application rate and N2O emissions (Shcherbak et al 2014).”
• Reconstruction of spatially detailed global map of NH 4 + and NO 3 − application in synthetic nitrogen fertilizer (2016, background): “Also, the type of fertilizer (e.g., nitrate salts, ammonium salts and urea, or anhydrous NH+4 ) determines other N oxide gas emissions from fertilized soil (Bouwman, 1996; Harrison and Webb, 2001; Shcherbak et al., 2014).”
• Nitrogen Fertilization. A Review of the Risks Associated with the Inefficiency of Its Use and Policy Responses (2021, background): “However, several recent studies in corn cropping systems have reported an exponential relationship between them [45,46].”
• Global evidence on nitrogen saturation of terrestrial ecosystem net primary productivity (2016, methodology): “Recently, Shcherbak et al (2014) proposed a new analysis method to identify the nonlinear response of soil N2O flux to N fertilization rates.”
• Global change pressures on soils from land use and management (2016, background): “Recent research indicates that the relationship between nitrogen application and N2O emissions is nonlinear, resulting in an increasing proportion of added N being emitted, as application rate increases (Philibert et al., 2012; Shcherbak et al., 2014).”
• Nitrification gene ratio and free ammonia explain nitrite and nitrous oxide production in urea-amended soils (2017, background): “In particular, substantial efforts have been made to characterize the functional responses (e.g., linear vs. non-linear) of N2O emissions to N fertilizer addition rates (Shcherbak et al., 2014).”
