Greenhouse gases emissions from agriculture (300 words)

Most farm-related emissions come in the form of methane (CH4) and nitrous oxide (N2O). Cattle belching (डकार) (CH4) and the addition of natural or synthetic fertilizers and wastes to soils (N2O) represent the largest sources, making up 65 percent of agricultural emissions globally. Most farm-related emissions come in the form of methane (CH4) and nitrous oxide (N2O). At the farm level, the relative size of different sources will vary widely depending on the type of products grown, farming practices employed, and natural factors such as weather, topography, and hydrology.

●        Agriculture (9.0 percent of 2017 greenhouse gas emissions) – Greenhouse gas emissions from agriculture come from livestock such as cows, agricultural soils, and rice production.

●        Agriculture Sector Emissions

Agricultural activities — crop and livestock production for food — contribute to emissions in a variety of ways:

●        Agricultural soils can lead to increased availability of nitrogenin the soil and result in emissions of nitrous oxide (N₂O). Specific activities that contribute to N₂O emissions from agricultural lands include the application of synthetic and organic fertilizers, the growth of nitrogen-fixing crops, the drainage of organic soil, and irrigation practices.

●        Livestock, especially ruminants such as cattle, produce methane (CH₄) as part of their normal digestive processes. This process is called enteric fermentation, and it represents almost one third of the emissions from the Agriculture economic sector.

●        The way in which manure from livestock is managed also contributes to CH₄ and N₂O emissions. Different manure treatment and storage methods affect how much of these greenhouse gases are produced. Manure management accounts for about 14 percent of the total greenhouse gas emissions from the Agriculture economic sector.

●        Smaller sources of agricultural emissions include CO₂ from liming and urea application, CH₄ from rice cultivation, and burning crop residues, which produces CH₄ and N₂O.

Cattle belching (CH4) and the addition of natural or synthetic fertilizers and wastes to soils (N2O) represent the largest sources, making up 65 percent of agricultural emissions globally. Smaller sources include manure management, rice cultivation, field burning of crop residues, and fuel use on farms.
