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

This research paper examines the loss of applied nitrogen (LAN) as nitrous oxide (N2O) and nitric oxide (NO) from N-fertilized tropical soils in the Venezuela savanna region, finding that emissions are significantly higher than IPCC default values.

• Nitrogen fertilization leads to a significant increase in soil fluxes of N2O and NO to the atmosphere. In the Venezuela savanna region, the study recorded a wide range of loss of applied nitrogen (LAN), with LAN-N2O ranging from 0.30% to 6.1% and LAN-NO ranging from 0.26% to 2.1%, resulting in overall average values of 1.9% and 0.9% respectively.
• The loss of applied nitrogen is primarily influenced by rainfall patterns and soil texture, which impact water-filled pore space and soil moisture. Additionally, the chemical composition of the N fertilizer and soil management practices, specifically tillage (T) and no-tillage (NT), play important roles.
• The overall average LAN-N2O of 1.9% is approximately double the IPCC default value of 1%, suggesting that cropping systems in tropical savanna regions require a higher emission factor.
