  "Description": "An implementation of the ALFAM2 dynamic emission model for\nammonia volatilization from field-applied animal slurry (manure\nwith dry matter below about 15%). The model can be used to\npredict cumulative emission and emission rate of ammonia\nfollowing field application of slurry. Predictions may be\nuseful for emission inventory calculations, fertilizer\nmanagement, assessment of mitigation strategies, or research\naimed at understanding ammonia emission. Default parameter sets\ninclude effects of application method, slurry composition, and\nweather. The model structure is based on a simplified\nrepresentation of the physical-chemical slurry-soil-atmosphere\nsystem. More information is available via citation(\"ALFAM2\").",
