The emissions arise during manure storage, where nitrogen is converted through microbial processes, and after land application, where manure nitrogen enters the same nitrification-denitrification pathways as synthetic fertilizer.<\/p>\n<h2>Manure Management Systems<\/h2>\n<p>The magnitude of manure N\u2082O emissions depends strongly on the management system used. Liquid slurry systems stored in covered or uncovered tanks have different emission profiles than solid composting, pasture deposition, or anaerobic digestion systems. Anaerobic digesters, which capture methane for energy, can simultaneously reduce N\u2082O if the digestate is managed appropriately.<\/p>\n<div class=\"atmo-data-box\">\n<div class=\"atmo-data-box__title\">System Emission Factors (kg N\u2082O-N\/kg N)<\/div>\n<p>Pasture\/range: 0.008\u20130.02<br \/>\nSolid storage: 0.005\u20130.015<br \/>\nLiquid slurry (open): 0.001\u20130.005<br \/>\nAnaerobic digestion: 0.0\u20130.002<br \/>\nLand application adds: 0.01 additional<\/div>\n<h2>Mitigation Opportunities<\/h2>\n<p>Improving diet formulation to reduce protein in animal feed directly decreases the nitrogen content of manure, reducing emission potential throughout the manure chain.
