“…Acidification was more dependable than injection in reducing ammonia emissions Acidification proved efficient in minimizing NH 3 emissions to insignificant levels relative to bandspread US, because the AS treatment resulted in 90-99% reductions of NH 3 emission rates during three measurements periods on the day of slurry applications in the 2017 and 2018 study years. This finding agrees with the study by Hagner et al (2021) conducted in the same experimental field area in 2019 with cattle slurry acidified by H 2 SO 4 or pyrolysis liquid before band spreading to grass ley. During the consecutive years of 2017-2019 in these two studies, the average cumulative NH 3 -N losses were estimated to represent roughly only 2% of the NH 4…”

“…Sommer et al 1991;Sommer and Hutchings 2001;Ha ¨ni et al 2016). Compared with the NH 3 emission rates from band-spread US in 2018, the higher emissions recorded in 2017 in the present study and in 2019 in the study by Hagner et al (2021) were probably attributed to the higher air temperature prevailing on the slurry spreading day. Relative dry topsoil conditions were assumed to allow infiltration of slurry into the soil, whereas organic matter-related soil water repellency may have a restrictive effect on water infiltration in grasslands (Rasa et al 2007).…”

“…In the current study, apparent recoveries of manure total N remained generally low (11-15% in 2017 and 17-28% in 2018). Hagner et al (2021) reported roughly similar values in a field experiment conducted in the same area in 2019. In their study, the apparent total N recovery was 10% from band-spread untreated cattle slurry and 18% from similarly applied acidified slurry.…”

“…The NH 3 volatilization rates from slurry-treated plots were measured using the equilibrium concentration technique (JTI method) as in Hagner et al (2021). The method combines the stirred dynamic chamber method with a passive diffusion sampler technique and enables simultaneous field measurements in small plots (Svensson 1994;Mattila 2006).…”

Ammonia (NH3) constitutes the single largest loss of manure nitrogen (N), making measures targeted at reducing its emissions meaningful for the environment and the overall efficiency of manure N use. In this study, the performance of two emission-reducing techniques, acidification and injection, were studied in a field experiment with grass ley over two growing seasons. Emissions of NH3, crop growth, and N use efficiency were determined from plots fertilized with cattle slurry either band spread, injected or band spread after acidification. The approximate cumulative NH3 losses from the plots with band-spread untreated slurry amounted to about 22 kg NH3-N ha−1 over the observation periods in 2017 and 10 kg NH3-N ha−1 in 2018. The injection and acidification reduced the estimated cumulative NH3 emissions by 43 and 95% respectively in 2018, and both by 97% in 2017. In 2017, the emission-reducing techniques had no impacts on crop growth, but in 2018, acidification increased dry matter yield by 29% and apparent N recovery by 65% compared with band-spread untreated slurry. According to the current results, acidification consistently produced the lowest NH3 emissions and a discernible positive yield effect. It can therefore be recommended instead of injection for reducing NH3 emissions in boreal grass cultivation.

“…Pyrolysevloeistoffen zijn waterige oplossingen die een breed scala aan organische verbindingen bevatten, met azijnzuur als meest voorkomende, gevolgd door methanol, hydroxyaceton, mierenzuur, furfural en propaanzuur in een volgorde die varieert afhankelijk van het uitgangsmateriaal en de procestechnologie (Hagner et al, 2021). In een studie werd een ammoniakemissiereductie van circa 99% bereikt met aanzuren met pyrolysevloeistoffen op het moment van uitrijden van rundermest, even groot als het effect van zwavelzuur (ibid.).…”

Perspectief van het aanzuren van mest in Nederland om methaan-en ammoniakemissie te reduceren. Wageningen Livestock Research, Rapport 1375.Samenvatting NL: Het aanzuren van mest is een kansrijk principe om de methaan-(uit mest) en ammoniakemissies te reduceren. Mest aanzuren heeft echter in Nederland geen voet aan de grond gekregen, onder andere door de hogere kosten van deze systemen ten opzichte van ammoniakemissiearme vloeren, de noodzaak van een externe mestopslag, zorgen over de mogelijke risico's op verzuring en verhoogde concentratie zwavel in de bodem en in het grond-en oppervlaktewater. Ten aanzien van emissies lag in Nederland lange tijd de focus met name op ammoniak. Vanwege de problematiek van klimaatverandering en de internationale en nationale klimaatdoelstellingen is daar de noodzaak bijgekomen om methaanemissies in de landbouw te beperken. In samenhang met de hardnekkige stikstofcrisis en de behoefte aan integrale oplossingen zou de balans ten aanzien van mest aanzuren mogelijk naar de andere kant kunnen omslaan.Het doel van deze studie is daarom om kansen en belemmeringen voor de implementatie van systemen voor het aanzuren van mest in Nederland te identificeren.Summary UK: The acidification of manure is reported as a promising measure for reducing the emissions of ammonia and (manure related) methane. However, this measure has not been implemented in the Netherlands because of, among other reasons, the high costs compared to available flooring systems, the need for manure storage outside the barns, and concerns about the possible acidification of the soil and an increased concentration of sulfur in soils and surface water. Regarding emissions, the focus in the Netherlands was mainly on ammonia. Due to climate change and related national and international agreements, objectives are also being formulated regarding methane emissions. Therefore, the aim of this research is to identify opportunities and barriers for the implementation of manure acidification in the Netherlands.
