Greenhouse gases absorb and emit solar radiant energy and cause the greenhouse effect. The primary greenhouse gases are carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4), and ozone (O3).
The agricultural sector contributes about 10%–14% of global greenhouse gas emissions. The greenhouse gases that emit from agricultural activities are carbon dioxide, methane, and nitrous oxide. Methane gas is released into the atmosphere as a result of enteric fermentation from the castles. Further, the preparation of soil and land, as well as the burning of agricultural waste, contributes to the emission of carbon dioxide into the atmosphere.
The application of nitrogen-containing synthetic fertilizers and animal waste contributes to the emission of nitrous oxide. Nitrous oxide is produced by the Denitrifying soil microbes (Pseudomonas sp., Alcaligenes sp., and Bacillus sp.) using nitrogen-containing fertilizers.
