“…Acidification is effective in NH 3 mitigation, with a reduction efficiency of 56% ( P < 0.05). It also results in a high CH 4 mitigation efficiency (88%, P = 0.068) as methanogenesis is inhibited in the acidified slurry. , …”

Gaseous emissions from animal manure are considerable contributor to global ammonia (NH) and agriculture greenhouse gas (GHG) emissions. Given the demand to promote mitigation of GHGs while fostering sustainable development of the Paris Agreement, an improvement of management systems is urgently needed to help mitigate climate change and to improve atmospheric air quality. This study presents a meta-analysis and an integrated assessment of gaseous emissions and mitigation potentials for NH, methane (CH), and nitrous oxide (NO) (direct and indirect) losses from four typical swine manure management systems (MMSs). The resultant emission factors and mitigation efficiencies allow GHG and NH emissions to be estimated, as well as mitigation potentials for different stages of swine operation. In particular, changing swine manure management from liquid systems to solid-liquid separation systems, coupled with mitigation measures, could simultaneously reduce GHG emissions by 65% and NH emissions by 78%. The resultant potential reduction in GHG emissions from China's pig production alone is greater than the entire GHG emissions from agricultural sector of France, Australia, or Germany, while the reduction in NH emissions is equivalent to 40% of the total NH emissions from the European Union. Thus, improved swine manure management could have a significant impact on global environment issues.

“…Particularly, between Days 60 and 90 (peak CH 4 /CO 2 ratios in most incubations), slurries treated with Na 2 S 2 O 8 , KMnO 4 , and their combination had stronger impacts on CH 4 /CO 2 ratios ( p < 0.001, Tukey's test), and hence on potential CH 4 production. In addition to reducing CH 4 emissions, slurry acidification also reduces NH 3 emissions from stored liquid dairy manure (Petersen et al, 2012, 2014; Wang et al, 2014; Bastami et al, 2016); thus, further studies of slurries treated with chemical oxidants for potential reduction of NH 3 emissions may provide important options in mitigating greenhouse gas emissions from these systems.…”

Sodium Persulfate and Potassium Permanganate Inhibit Methanogens and Methanogenesis in Stored Liquid Dairy Manure

Stored liquid dairy manure is a hotspot for methane (CH) emission, thus effective mitigation strategies are required. We assessed sodium persulfate (NaSO), potassium permanganate (KMnO), and sodium hypochlorite (NaOCl) for impacts on the abundance of microbial communities and CH production in liquid dairy manure. Liquid dairy manure treated with different rates (1, 3, 6, and 9 g or mL L slurry) of these chemicals or their combinations were incubated under anoxic conditions at 22.5 ± 1.3°C for 120 d. Untreated and sodium 2-bromoethanesulfonate (BES)-treated manures were included as negative and positive controls, respectively, whereas sulfuric acid (HSO)-treated manure was used as a reference. Quantitative real-time polymerase chain reaction was used to quantify the abundances of bacteria and methanogens on Days 0, 60, and 120. Headspace CH/CO ratios were used as a proxy to determine CH production. Unlike bacterial abundance, methanogen abundance and CH/CO ratios varied with treatments. Addition of 1 to 9 g L slurry of NaSO and KMnO reduced methanogen abundance (up to ∼28%) and peak CH/CO ratios (up to 92-fold). Except at the lowest rate, chemical combinations also reduced the abundance of methanogens (up to ∼17%) and CH/CO ratios (up to ninefold), although no impacts were observed when 3% NaOCl was used alone. With slurry acidification, the ratios reduced up to twofold, whereas methanogen abundance was unaffected. Results suggest that NaSO and KMnO may offer alternative options to reduce CH emission from stored liquid dairy manure, but this warrants further assessment at larger scales for environmental impacts and characteristics of the treated manure.

“…At the end of composting, the value of the compost germination index that came from inoculated manure was higher than that of the control by 60%. Bastami et al [111] focused their research on the pig manure storage stage, since in this stage, microbial processes and chemical reactions result in a large release of gases such as methane, nitrous oxide, ammonia, or carbon dioxide, which contribute to the generation of unhealthy environments in the farm. These authors examined how methane emissions evolved from slurry storage under two temperatures (cold, 10 °C and warm, 30 °C) when a 10% (w/w) solution of EM in a substrate rich in glucose was applied.…”

The traditional logic behind effective microorganism is based on a media inoculation with mixed cultures of beneficial microorganisms to create a more favorable environment for plant growth and health when the media is the soil. Following this rationale, other research works have been focused on studying the effect of effective microorganisms when they are used as manure stabilizing agents, in some cases by including them in animal diets, reporting, in all cases, beneficial properties. However, the use of effective microorganisms is not yet widespread. One reason may be that no rigorous research has so far been done on the actual utility of these mixed cultures on manure stabilization and crop production. In this work, the potential uses of effective microorganisms are shown with the focus on evaluating the influence of these mixed cultures on the biostabilization of manure before its use as fertilizer. This work also presents some new perspectives on the role and application of effective microorganisms as microbial inoculants to achieve a microbiological balance of manure so that it can improve its quality, increasing production and protection of crops when applied as fertilizer, helping to conserving natural resources and creating a more sustainable agriculture and environment. Finally, this document also reviews strategies on how to improve the effect of effective microorganisms after their inoculation into the soil as part of the manure.
