Losses of NO and N2O emissions from Venezuelan and other worldwide tropical N-fertilized soils

Research in the Venezuela savanna region found that nitrogen fertilization leads to significant N2O and NO soil fluxes, with average losses of 1.9% and 0.9% respectively. These values were influenced by soil texture, rainfall patterns, soil management (tillage vs. no-tillage), and fertilizer composition. Notably, the average LAN-N2O is approximately double the IPCC default value of 1%, suggesting a need for higher emission factors for tropical savanna cropping systems.

• The loss of applied nitrogen was primarily driven by rainfall patterns and soil texture, which influenced water-filled pore space and soil moisture, as well as the chemical composition of the N fertilizer and soil management practices (tillage and no-tillage).
• The average LAN-N2O observed in the study is roughly twice the IPCC default value of 1%, indicating that higher factors should be applied to cropping systems in tropical savanna regions.
