PRODUCTION NITROUS OXIDE (N2O) IN DIGESTIVE PROCESSES OF RUMINANTS AND THE POSSIBILITY OF ITS REDUCTION
Keywords:
climate change, denitrification, dung, environment, greenhouse gas, livestock, mitigation emissions, Nitrogen, nitrous oxide, urineAbstract
The biological denitrification process is described schematically. It is seen that the nitrates are reduced to nitrogen passing subsequently from nitrite and nitrogen oxides to nitrogen. The major sources of nitrous oxide emissions, the role of agriculture and livestock production in particular have been defined.
Studied are 246 substances used as forage additives. In theory, they are divided into ten groups depending on their environment impact. The studies of thirty-two leading scientists in this field have been analyzed. Studies have been focused on seeking possibilities to reduce emissions of nitrous oxide whose impact on global warming is 296 times bigger than that of the carbon dioxide.
The authors conclude that further studies are needed, both for the quantification of nitrous oxide, and the possibilities for its reduction, including its slower release. Studies on these issues in our country have just started.
