“…The wind tunnel ventilation intensity changed in the air extraction duct (4) using valve (8), changing the duct cross-sectional area and changing the fan speed (9) by the frequency converter. The air samples were taken from the duct with probes (5) and the heated hose (12) was supplied to the GME700 gas analyzer (13). The GME700 laser gas analyzer performs "coordinated" complex process analysis.…”

“…The air in the analyzer was supplied by an uninterrupted pump (15) with a capacity of 6 l min −1 . To prevent air condensation, it was warmed up in the intestine (12) and heated to 150 • C in the electrically heated valve (14). The test gas analyzer (13) was programmed to record the concentration of ammonia gas every 1 min.…”

“…Air pollution, eutrophication, and soil acidification cause reactive nitrogen emissions into the atmosphere [8][9][10][11]. Ammonia emission sets up with all manure management moments-keeping of animals, grazing, storage, and divert injection reduce ammonia emission into the soil [12,13]. The principal key categories for NH 3 emissions are animal manure applied to soils, inorganic N-fertilizers, and manure management.…”

Increasing control of localized air pollution caused by ammonia is identified, including limiting the maximum emissions from agriculture. In EU countries, the agricultural sector is the source of above 94% of the total anthropogenic emissions of ammonia, of which manure removal systems account for 56%. In view of the reason for the agricultural waste management by formation and propagation of ammonia gas—the bacterial and enzymatic degradation of organic components in excrement—it is important to evaluate the effect of biotreatment of 100% natural composition (contain Azospirillum sp. (N) (number of bacterial colonies −1 × 109 cm−3), Frateuria aurentia (K) (number of bacterial colonies −1 × 109 cm−3), Bacillus megaterium (P) (bacterial colony count −1 × 109 cm−3), seaweed extract (10% by volume), phytohormones, auxins, cytokinin, gibberellins, amino acids, and vitamins) on the emission of ammonia from organic waste. Experimental research was carried out to determine significant differences of dynamics in agrochemical composition of manure, NH3 gas emissions, depending on biotreatment, manure storage duration, and ventilation intensity of the barn. Gas emission was obtained via laser gas analyzer using a spectroscopic method in a specially reconstructed wind tunnel chamber. About 32% manure biotreatment effect on reduction of ammonia emissions was established. The maximum effect of the biodegradable compound on gaseous propagation was assessed after 28–35 days of manure storage and proved all biotreatment effect time of 49–56 days. By the saving nitrogen loses priority, manure biotreatment could reduce nitrogen losses from manure and inorganic N fertilizers by approximately 5%, also could reduce approximately 5911.1 thousand tones nitrogen fertilizer in the world and reduce approximately 5.5 Eur ha−1. “The biotreatment impact assessment confirmed that proper application of biotreatment can reduce ammonia emissions from manure and environmental pollution from agriculture”.

The article analyses the sources of ammonia (NH 3 ) emissions in Latvia and the trends from 2005 to 2018 with the focus on agricultural production. The study is based on the annual Latvia's Informative Inventory Report 1990 -2018 submitted under the Convention on Long -Range Transboundary Air Pollution Annex I data. It is crucial to decrease NH 3 emissions due to their toxic nature to the ecosystems and health of living beings as NH 3 not only contributes to acidification of water ecosystems, but also to formation of secondary particles. There is a trend of increase of NH 3 emissions from agriculture production in the study period (+12% comparing 2018 to 2005) opposed to the need to reach the national goal to decrease NH 3 emissions to the reference accounted in 2005 (1% NH 3 reduction). There is decrease of NH 3 emissions for about 5% from agriculture comparing 2018 and 2017 due to rapid decrease of farming animals. The largest increase of NH 3 emissions in the latest years in Latvia is observed from the use of inorganic fertilizers (+57%), because there is increase of the incorporated nitrogen (N) to soils. The lowest use of inorganic fertilizers was in 1995 (11.5 kt N) in the inventory period 1990 -2018. There is decrease of emissions from the whole manure management cycle about 6% comparing 2018 to 2005. However, manure management is still the biggest source of NH 3 emissions (73% from agricultural NH 3 emissions), therefore, with the highest potential to decrease national NH 3 emissions as there are plenty of options to limit NH 3 from manure in all stages of livestock breeding and manure management (feeding, livestock housing, manure storage and application to soils). To reach the goal of NH 3 emissions reduction these all measures need to be accountable by developing a national model for estimation of annual NH 3 emissions, which should be based on detailed statistical data about manure management practices.
