“…The di!erence in emission pattern may re#ect that the temperature in these two experiments was high in a longer period than in the present study. The emission was low compared with emissions from untreated manure heaps determined by Sibbesen and Lind (1993) and Petersen et al (1998).…”

“…Mahimairaja et al (1995) did not detect N 2 O production from fresh manures of poultry, horse, swine, dairy cattle or sheep. Sibbesen and Lind (1993) found that concentrations of N 2 O at any depth in solid manure piles were higher in sow and piglet manure than in dairy cattle manure. Furthermore, the concentration of N 2 O was higher in 1-mo old piles compared with fresh manure piles.…”

. 2001. Nitrous oxide production by manure samples collected from six manure-handling systems. Can. J. Soil Sci. 81: 33-38. Stored manures are often considered to be source of nitrous oxide (N 2 O). A study was done to identify manure characteristics and handling stages related to N 2 O production. In two laboratory experiments we investigated the production of N 2 O from several animal manures collected at different stages of manure handling or locations in stored-manure systems. Denitrifying enzyme activity, denitrification and CO 2 production rates and chemical and fibre characteristics of manure samples were also determined. Most samples had low rates of N 2 O production. Exceptions were open piles of fresh beef manure and the moist surface layer near the base of an open pile of poultry manure. Production of N 2 O was most highly correlated with nitrite plus nitrate (NO 2 -+ NO 3 -) content of manure regardless of whether results were expressed on a wet or a dry weight basis. Denitrification was the most probable source of N 2 O because N 2 O production with acetylene and denitrifying enzyme activities was higher than N 2 O production without acetylene. Stored manure is potentially an important source of N 2 O emissions, particularly when storage conditions are conducive to formation of (NO 2 -+ NO 3 -).

This work presents results of a survey of case studies to quantify the potential energy production and GHG emission changes of anaerobically digesting (AD) cattle manure in three Guatemalan dairy farms. Livestock inventory and energy consumption data were collected and used to define three scenarios for each farm: baseline, AD with condensing boiler (AD-boiler) and AD with combined heat and power unit (AD-CHP). The estimated emissions account for enteric fermentation, manure/digestate handling, import/export of thermal energy and electricity and use of fossil fuels for transport. The AD systems result in a production of 100±37 kg CH4 · head 1 · yr 1 . If this CH 4 is combusted in the AD-boiler scenarios, 5.00±1.59 GJ · head 1 · yr 1 of thermal energy is generated and emissions from baseline scenarios are offset by 600±280 kg CO2e · head 1 · yr 1 . The generated heat is sufficient to operate digesters (308 K) and export 2.90±0.62 GJ · head 1 · yr 1 . Challenges are found to use that thermal power because domestic heating is inessential. AD-CHP is found to be more suitable because it produces sufficient thermal energy for the digesters (2.50±0.80 GJ · head 1 · yr 1 ) while generating electric power (1.80±0.57 GJ · head 1 · yr 1 ). This scenario could promote the welfare of neighboring communities by making sustainable electricity available. AD-CHP could offset 400±320 kg CO2e · head 1 · yr 1 from the baselines.
