Synthetic nitrification inhibitors have been developed to promote plant N uptake by reducing losses via NH3 leaching or denitrification.Research has re-focussed to mainly consider effects of nitrification inhibitors on both direct and indirect N2O emissions from N amendments to soil (Di and Cameron, 2012). Laboratory studies (Hatch et al., 2005) report greater inhibition of N2O than field studies. Dittert et al., (2001) suggests that soil conditions, variations in temperature or leaching/runoff after excessive rainfall, reduces the effect of nitrification inhibitors. Efficiency of nitrification inhibitors declines linearly with soil temperature above 10°C (higher nitrification rates and rapid nitrification inhibitors degradation; Subbarao et al., 2006).
