Title: A LABORATORY STUDY OF AMMONIA VOLATILIZATION FROM CATTLE AND PIG SLURRY
Abstract: A laboratory study was undertaken to determine the effects of (a) moisture loss, (b) pH change and (c) the addition of chemicals to slurry on ammonia volatilization from pig and cattle slurry during drying. A positive relationship was established between moisture loss and ammonia loss. It was shown that by reducing slurry pH, ammonia volatilization can be prevented and ammonia loss can be reduced by the addition of aluminium chloride, ferric chloride, calcium chloride and other chemicals to slurry. An explanation is proposed for the loss of ammonia from slurry. Laboratory experiments showed that more ammonia was retained by pig slurry than by cattle slurry on drying.
