原始语种摘要: On-farm manure-nitrogen (N) losses as ammonia (NH3), nitrous oxide (N2O), nitrogen oxide (NO), nitrogen (N2), and nitrate leaching/ runoff constitute a considerable environmental problem and devaluates manure nutrients. Quantifying N loss fractions [(kg (N loss) (kg manure-N)-1) for animal manure storage systems is critical to develop national or regional emission inventories and mitigation strategies. Emission fractions of NH3-N, N2O-N, NO-N, and N2-N and the loss fraction of nitrate-N leaching/runoff were developed for the primary beef and dairy cattle manure storage systems (i.e., compost, stockpile, feedlot manure pack, liquid tank, slurry pit, and lagoon/earthen storage) in ecoregions of Alberta and Ontario, two of the largest beef production provinces in western and eastern Canada,...
