Estimation of Carbon Footprint Equivalent of Soil Nitrogen Loss Due to the Sugar Beet Harvest in Turkey

imga2019, News

“Estimation of Carbon Footprint Equivalent of Soil Nitrogen Loss Due to the Sugar Beet Harvest in Turkey: A Review” at Successful Transformation toward Land Degradation Neutrality: Future Perspective" 17-19 June 2019, Ankara, ATO Congresium. Marking the 25th anniversary of the UN Convention to Combat Desertification (UNCCD)

Higlihts of the study:

1-Average soil lost due to the sugar beet harvest is about 3.41 Mg ha-1 y-1,

2-Total amount of soil nitrogen loss≈2151 Mg y-1,

 3-Production of nitrogenous fertilizer requires high energy consumption, emitting large amounts of CO2 (carbon footprint equivalent) to atmosphere. The carbon footprint of the world average N- fertilizer  production given as of 5.66 Mg CO2  eqv./Mg Nitrogen. Hence, the annual carbon footprint equivalent is calculated as 12045 Mg CO2 eqv. /Mg Nitrogen fertilizer manufactured.

4- The fertilizer production to replace the nitrogen lost releases about 12045 Mg CO2 eq. /Mg Nitrogen fertilizer. Although this figure seems low, nitrogent losses and GHG emissions warrant consideration of soil management practices to reduce soil lost due to root crop harvests.


1-      Deadly  flush  floods in Turkey and Southern Europe

2-      Global Atmosferic COincrease, Climate Change and Food Security

3-      Climate Change, Land  Degradation  and  Migration: Challenges for the EU and  Africa,
