Agricultural activities associated with crop and animal production include tillage, application of fertilizer and pesticides, harvesting, and controlled burning, as well as housing of animals and storage of animal waste (manure). These components of production result in the loss of trace gases and particulate matter to the atmosphere. Trace gases emitted from animal manure and fertilized soils include greenhouse gases (methane and nitrous oxide), reactive precursors (ammonia and nitric oxide) of secondary atmospheric pollutants, and odorous compounds (volatile organic compounds), while tillage and harvesting are sources of particulate matter. Ventilation of animal housing and burning of crop residues are sources of both trace gases and particulate matter. While progress has been made in characterizing emissions from some agricultural sources, large uncertainties persist in emission factors for many source categories and compounds. Furthermore, emission models are, in many cases, insufficient for scaling up observations to larger areas and for testing mitigation strategies.
This special issue welcomes measurement and modeling oriented papers that examine emissions from agricultural sources, the underlying emission processes, and options for mitigating emissions. Submission of papers that address the atmospheric transport, transformation, and deposition of agriculturally emitted compounds is also encouraged.
