The agricultural development of Korea has occurred at the expense of natural resources and environmental quality, and, today, one of the most urgent problem in the practices of intensive livestock farming is disposing of the animal wastewater. As a result, soil and water degradation and other environmental deterioration become apparent and they cause long-term loss in agricultural production. This paper attempted to summarize the environmental problems associated with agricultural activities, and to get some implications to minimize agricultural environment problems. It is proposed that sustainable agricultural is one of desirable directions for future Korean agriculture. The goal of the sustainable agricultural effort is to utilize the potential environmental quality problem. Agricultural operations may be more dependent upon the production practices and waste management techniques utilized by farmers than the size of the operation, the number of animal fed, or amount of waste involved. Also low-input farming technology can be suggested one of them, and disposing system of agricultural residues and animal waste should be developed with intensive concerns and financial supports.
