Emissions of ammonia and methane from agriculture caused by microbes in manure are an increasing challenge to sustainable agriculture. We screened several commercially available polyphenols, phenolic compounds, polyphenol-rich extracts for their ability inhibit the production mitigate emissions pig absence presence sodium fluoride (NaF) using a short-term high-throughput set-up. Tested compounds were chlorogenic acid, lignosulfonic lignin, chitosan, green tea extract, chestnut tannins. Green at concentration 8.5 mg/ml with 1 mM NaF, reduced total nitrogen (TAN) 72%, while lowered 95% extract 2.5 mg/ml. The four plant waste (spent coffee grounds, noble fir needles, shea meal, rapeseed press cakes) methanogenesis was also investigated. Adding 7.0 ± 0.7 fir, or cake, 3.2 ground TAN approximately 50%. Shea meal had largest effect on emissions, reductions 60%. Gallocatechin- epigallocatechin-rich appeared be especially potent inhibition could inhibited variety Based current work, we conclude that certain plants have potential use management reduce emissions.

Effects of surfactant, oxidant, and flocculant treatments on methane emission from pig slurry during storage

Reducing methane (CH4) emission from livestock production can be achieved by the treatment of manure in slurry pits and storage tanks. In case pits, treating residual left out after frequent flushing largely reduce CH4 due to decrease methanogenic inoculum. this study, three surfactants, two oxidants a flocculant were screened for their efficiency reducing pig headspace setup. All surfactants reduced > 95% at dosage 8 g kg−1 particularly sodium dodecyl sulfate (SDS) was effective low only 2.5 with >95% reduction. Oxidants 30–85% different dosages, hypochlorite being most effective. Flocculant did not emissions significantly. None studied treatments ammonia Similarities pathway observed among surfactant treated slurries, oxidant slurries. Considering cost environmental effects additives, SDS seems promising choice. Future work on could either as combination other additives or up-scaling designing solutions houses.
