Summary: | Human activities have caused an increase in greenhouse gas emissions, resulting
in climate change that affects many factors of human life including its effect
on water and food quality in certain areas with implications for human health.
CH4 and N2O are known as potent non-CO2
GHGs. The livestock industry contributes to direct emissions of CH4
(38.24%) and N2O (6.70%) through enteric fermentation and manure
treatment, as well as indirect N2O emissions via NH3
volatilization. NH3 is also a secondary precursor of particulate
matter. Several approaches have been proposed to address this issue, including
dietary management, manure treatment, and the possibility of inhibitor usage.
Inhibitors, including urease and nitrification inhibitors, are widely used in
agricultural fields. The use of urease and nitrification inhibitors is known to
be effective in reducing nitrogen loss from agricultural soil in the form of
NH3 and N2O and can further reduce CH4 as a
side effect. However, the effectiveness of inhibitors in livestock manure
systems has not yet been explored. This review discusses the potential of
inhibitor usage, specifically of N-(n-butyl) thiophosphoric triamide,
dicyandiamide, and 3,4-dimethylpyrazole phosphate, to reduce emissions from
livestock manure. This review focuses on the application of inhibitors to
manure, as well as the association of these inhibitors with health, toxicity,
and economic benefits. |
