Ammonia pollution is pollution by the chemical ammonia (NH 3) – a compound of nitrogen and hydrogen which is a byproduct of agriculture and industry. Common forms include air pollution by the ammonia gas emitted by rotting agricultural slurry and fertilizer factories while natural sources include the burning coal mines of Jharia , the caustic ...
Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia from cattle waste continue to raise concerns over environmental pollution. [3]
In 2022, greenhouse gas emissions from rice cultivation were estimated at 5.7 billion tonnes CO2eq, representing 1.2% of total emissions. [59] Within the agriculture sector, rice produces almost half the greenhouse gas emissions from croplands, [60] some 30% of agricultural methane emissions, and 11% of agricultural nitrous oxide emissions.

These substances are emitted through two main pathways: gas emissions and lagoon overflow. Gas emissions are continuous (though the amount may vary based on the season) and are a product of the manure slurry. The most prevalent gasses emitted by the lagoon are: ammonia, hydrogen sulfide, methane, and carbon dioxide. Lagoon overflow is caused by ...
Conservation agriculture relies on principles of minimal soil disturbance, the use of mulch and/or cover crops as soil cover, and crop species diversification. [47] It enables the reduction of fertilizers, which in turn reduces ammonia emissions and greenhouse gas emissions.
Animal agriculture contributes to global warming, which leads to ocean acidification. This occurs because as carbon emissions increase, a chemical reaction occurs between carbon dioxide in the atmosphere and ocean water, causing seawater acidification. [184] The process is also known as the dissolution of inorganic carbon in seawater. [185]
Agricultural sources of reactive nitrogen can produce atmospheric emission of ammonia (NH 3), nitrogen oxides (NO x) and nitrous oxide (N 2 O). Combustion processes in energy production, transportation, and industry can also form new reactive nitrogen via the emission of NO x, an unintentional waste product.
Human activities account for over one-third of N 2 O emissions, most of which are due to the agricultural sector. [2] This article is intended to give a brief review of the history of anthropogenic N inputs, and reported impacts of nitrogen inputs on selected terrestrial and aquatic ecosystems .
