The production of hydrogen sulfide from stored liquid swine manure as influenced by the manure settling characteristics and the initial sulfate concentration was studied in the laboratory. The manure was settled in a 30-cm diameter ×120-cm high colu

This article reports a laboratory study of swine manure decomposition in a deep pit. Distributions of solids, organic matter, pH, and ammonia in fresh swine manure after 12 h settling in a 1.2 m column were characterized, and solids reduction and amm

This paper presents a computer model for predicting ammonia release rates from manure pits in swine buildings. The model couples ammonia diffusion and generation in the manure with ammonia release from the manure surface. Ammonia release rates and co

The corrosion potential of steel products exposed in animal buildings caused by microorganisms was investigated by determining the presence of bacteria on metal surfaces. In an initial study, scrapings (1 g from sample surface) of several corroded me

Two odor evaluation methods were tested during a 12-week dynamic experiment on the effects of a commercial additive on swine manure in anaerobic storage. One method was a rating method which combined many of the best features of past research methods
