Abstract Emissions of ammonia (NH3) and greenhouse gases (GHG) from digested pig manure storage have negative agronomic and environmental implications. The study was undertaken to evaluate how temperature affects NH3, GHG (i.e., methane (CH4) and nitrous oxide (N2O)) and nitric oxide (NO) emitted from a pig manure based biogas digester effluent (BDE) storage system.

Nitrous oxide is mainly generated during manure ammonia decomposition.

Nitrous oxide estimates also require livestock population and manure management practice data. The value and source of these data should correspond with that used for estimating methane emissions. Reporting of emission estimates for both methane and nitrous oxide is clearly described in the IPCC Guidelines.

A model has been developed to predict pig manure evolution (mass, dry and organic matter, N, P, K, Cu and Zn contents) and related gaseous emissions (methane (CH 4 ), nitrous oxide (N 2 O) and ammonia (NH 3 )) from pig excreta up to manure stored before spreading. This model forms part of a more comprehensive model including the prediction of pig excretion. Livestock, especially ruminants such as cattle, produce methane (CH 4) as part of their normal digestive processes.

About one third of the NH3 emissions from the anaerobically stacked farmyard manure occurred after spreading. Total N losses were at a low level with both storage systems. Greenhouse gas emissions (N2O and CH4) were much higher from the anaerobically stacked farmyard manure than from the composted one. As these are ecologically harmful gases, they have to be considered when judging the form of manure treatment.
