Description: An implementation of the ALFAM2 dynamic emission model for
        ammonia volatilization from field-applied animal slurry (manure
        with dry matter below about 15%). The model can be used to
        predict cumulative emission and emission rate of ammonia
        following field application of slurry. Predictions may be
        useful for emission inventory calculations, fertilizer
        management, assessment of mitigation strategies, or research
        aimed at understanding ammonia emission. Default parameter sets
        include effects of application method, slurry composition, and
        weather. The model structure is based on a simplified
        representation of the physical-chemical slurry-soil-atmosphere
        system. More information is available via citation("ALFAM2").
