Greenhouse gases (GHGs) are atmospheric compounds that trap and retain heat. This natural process is vital for maintaining Earth's temperature. However, excessive GHG emissions from livestock manure lagoons and human activities like burning fossil fuels, deforestation, and landfill emissions intensify this effect and lead to global warming.
Greenhouse gas emissions from agriculture include:
- Manure management, consisting of methane and nitrous oxide emissions from manure storage
- Urea fertilizer usage
- Enteric fermentation during livestock production
- Emissions from agricultural soils and/or land use management changes
- Energy use on-farm
