In order to analyze environmental impact of livestock manure and organic fertilizers, this studyinvestigated livestock-breeding and pollution loads, the status of individual and public livestockmanure treatment facilities, and the status of production, supply and components of compost andliquid fertilizers in the Nonsan area. Also, on a trial basis, this study investigated the life cycle ofthe environmental impact of livestock manure and its organic fertilizers on stream, groundwater,and agricultural soil. The results are as follows.
Firstly, were detected the range of 0.13~1.32 μg/L of As, 0.004~0.467 μg/L of Cd and 0.5~9.2μg/L of Pb as a harmful substances which show lower concentrations than person preservationcriteria of water qualities and aquatic ecosystem. However, it is not clear that heavy metals affectenvironment such as stream, groundwater and agricultural soil. Secondly, this influence couldchange according to investigation time and treatment efficiency. As were detected large amountsof persistent organic pollutants(e.g. 14.24~38.47 μg/L of acetylsalicylic acid, 1.17~2.96 μg/L ofsulfamethazine, and 2.25~174.09 μg/L of sulfathiazole) in effluent from livestock farms and smallamounts of sulfathiazole(ND~1.63 μg/L) in the stream, it is necessary to monitor POPs atindividual and public livestock manure treatment facilities. However, significant environmentalimpact did not appear at groundwater and agricultural soil in the test area supplied with liquidfertilizers.
These results could be applied to investigate the environmental impact of livestock manurethrough a comprehensive livestock manure management information system.
