Liquid manure (slurry) storages are sources of gases such as ammonia (NH(3)) and methane (CH(4)). Danish slurry storages are required to be covered to reduce NH(3) emissions and often a floating crust of straw is applied. This study investigated whether physical properties of the crust or crust microbiology had an effect on the emission of the potent greenhouse gases CH(4) and nitrous oxide (N(2)O) when crust moisture was manipulated ("dry", "moderate", and "wet"). The dry crust had the deepest…

Inhibition of methane oxidation in a slurry surface crust by inorganic nitrogen: an incubation study.

In slurry surface crusts, MOB maintained activity at higher concentrations of NH and NO than reported for MOB in soils and sediments, possibly showing adaptation to high N concentrations in the slurry environment, and it appears that the effectiveness of surface crusting as CH sinks will depend on inorganic N concentrations.

Greenhouse Gas and Ammonia Emissions from Slurry Storage: Impacts of Temperature and Potential Mitigation through Covering (Pig Slurry) or Acidification (Cattle Slurry).

Storage of livestock slurries is a significant source of methane (CH) and ammonia (NH) emissions to the atmosphere, for which accurate quantification and potential mitigation methods are required.

Oxygen distribution and potential ammonia oxidation in floating, liquid manure crusts.

Old, natural surface crusts may develop into a porous matrix with high O2 availability that harbors an active population of aerobic microorganisms, including AOB which may contribute to a considerable reduction of ammonia emissions from slurry tanks with well-developed crusts.

Does overwintering change the inoculum effect on methane emissions from stored liquid manure?

Overall, removing inoculum in the fall reduced CH4 emissions from manure storage tanks; however, fall inoculum removal was less effective than in a previous study where inoculum was removed in the spring.

Emissions of ammonia, nitrous oxide, methane, and carbon dioxide during storage of dairy cow manure as affected by dietary forage-to-concentrate ratio and crust formation.

The results suggested that the formation of an air-dried crust resulting from the straw bedding present in the manure reduced drastically NH(3)-N, and CH(4) emissions, but was conducive of N(2)O production and emission.

Do Effective Micro-Organisms Affect Greenhouse Gas Emissions from Slurry Crusts?

Slurry crusts form on the slurry surface and act as a primary barrier to gaseous emissions and could also be a zone where CH4 is consumed by methane-oxidising bacteria present. However, slurry crusts

Activity of Type I Methanotrophs Dominates under High Methane Concentration: Methanotrophic Activity in Slurry Surface Crusts as Influenced by Methane, Oxygen, and Inorganic Nitrogen.

Examining conditions for CH oxidation by in situ measurements of oxygen and nitrous oxide, as a proxy for inorganic N transformations, in intact crusts using microsensors suggested that both Type I and Type II MOB were active, with Type I dominating high-concentration CH oxidation.

Pilot scale facility to determine gaseous emissions from livestock slurry during storage.

A comparison of pooled and averaged time point measurements of CO(2), CH(4), and N(2)O indicated that pooled samples account for the diurnal variations under realistic storage conditions.
