Modeling of ammonia losses in sprinkler application of animal wastes

Creator:: Pote, Jonathan W. (Jonathan Woodrome)
Abstract:: A model to predict ammonia losses from sprinkler applied animal wastes was developed; in order to accomplish this, a review of literature was performed to determine possible methods of predicting ammonia losses during sprinkling. As adaptability to a large variety of situations was considered of maximum importance, the number of...
