Scientific literature related to the processes controlling ammonia emissions from a manure covered feedlot surface will be reviewed. Information will be gathered from this review to formulate relationships for the controlling processes. Computer code will be developed to represent these processes in a simulation through time. This model will be incorporated in the Integrated Farm System Model (IFSM) where it will be used to simulate ammonia emissions from Texas feedlots. Simulated and measured emissions will be compared to determine the accuracy of the model.
