Decentralized anaerobic digestion (AD) of manure and organic residues is a possible strategy to improve carbon and nutrient cycling within agricultural regions, meanwhile generating renewable energy. To date, there has been limited adoption of decent

Sewage sludge (SS) contains beneficial plant nutrients and organic matter, and therefore application of SS on agricultural land helps close nutrient loops. However, spreading operations are restricted to certain seasons and hence the SS needs to be s

This study investigated the effect on greenhouse gas emissions during storage of digested sewage sludge by using a cover during storage or applying sanitisation measures such as thermophilic digestion or ammonia addition. In a pilot-scale storage fac

By recycling sewage sludge (SS) to productive land, its plant nutrients can be utilised. However, the use of organic fertilisers carries health risks and causes emissions of nitrous oxide (N2O), methane (CH4) and ammonia (NH3). One measure to sanitis

Emissions of the greenhouse gases (GHG), methane (CH 4 ) and nitrous oxide (N 2 O) from non-digested and digested cattle slurry were measured during storage in a pilot-scale facility and during subsequent field application. In three treatments, non-d

Slurry injection into grassland has advantages as it decreases ammonia losses, but may harm grassland plants. In two field experiments, four different types of knife/tine equipment were tested on three different grassland species (monocultures of red

Different mitigation techniques for greenhouse gas (GHG) emissions from pig slurry in storage and after field application were evaluated and specific emissions factors derived. Fluxes of methane (CH4) and nitrous oxide (N2O) were measured for one yea

Ammonia (NH 3 ) emissions originate predominantly from manure. In outdoor pig production, excretory behav- iour creates nitrogen (N) point loads. This study examined ammonia losses from pigs on grassland at two farms by calcu- lating N field balances

This study evaluated losses of N 2 O, CH 4 and NH 3 from a rotational grazing system for overwintering beef cattle which spend 1 month on pasture. The cattle density was 71 heifers/ha and they were moved weekly to a new feeding area within the main p

Livestock farming systems are major sources of trace gases contributing to emissions of the greenhouse gases (GHG) nitrous oxide (N 2 O) and methane (CH 4 ), i.e. N 2 O accounts for 10% and CH 4 for 30% of the anthropogenic contributions to net globa
