| Ammonia emissions are an important problem in agricultural systems. Organic pig production raises a claim to offer high animal welfare. However, gaseous emissions can exhaust out of outdoor runs. Many measurement technics to determine the ammonia volatilization in animal facilities exist. In outdoor runs it is necessary to define the air volume flow. In addition, the contaminated surface of the pig-yard is heterogeneous. Therefore, it is interesting if the ammonia concentration correlate with the amount of manure. The outdoor run has been divided in a matrix. The ammonia concentrations are determined with a multi-gas monitor (INNOVA 1312) in combination with a dynamic chamber. The study showed a difference in ammonia volatilization between roofed and... |
