Abstract:
Emission quantification from the agricultural sector, and especially from livestock manure
management, is relevant for assessing mitigation strategies and for inventory purposes. There are
different direct techniques used to monitor emissions from quiescent surfaces. Common techniques
include the closed static chamber and the open dynamic chamber. The aim of this study was
to evaluate and compare different direct methods, two dynamic hoods and one static hood, for
monitoring NH3 and greenhouse gas (GHG) emissions (N2O, CO2, and CH4) from different emission
sources. These sources are ammonia solutions and different by-products of manure (compost,
liquid fraction of digestate, and solid fraction of pig slurry). The use of dynamic hoods, despite
their differences in size, operation, and applied air flux, presents comparable emission rates for all
emissions and compounds assayed. These rates are always higher than those obtained using static
hoods. Therefore, it can be concluded that the use of dynamic hoods is a valuable technique for
refining the indirect estimation of emissions.
