- W572640147 abstract "Soil and water quality was monitored in the Nakdong River basin to assess the impact of different agricultural practices. From five catchments, soil samples were collected at three times during 1996 to 1998, and water samples were collected at twelve times on July during 1995 to 1999. The major agricultural practices were paddy and upland farming in three areas surveyed: Youngju, Goryung, and Milyang. Apple orchards were located along in the Imgo-Cheon catchment. Intensive vegetable farming in plastic fIlm house was practiced in the Habin-Cheon catchment. Total N contents, 0.04-0.32%, of paddy soils were low in comparison with those of upland, orchard, and plastic film house soils. Available phosphate() contents, , in plastic film house soils were higher than those in paddy soils. In plastic film house and upland soils, CEC of soils were high. The N concentrations in most of the streams were higher than , the standard of agricultural irrigation water. The P concentrations were above , the standard of agricultural irrigation water and were higher than the minimum level for eutrophication, in most of the streams. In conclusion, nutrients by agricultural activity could affect water quality of streams near the agricultural fields. Good water quality in streams can be maintained by proper management of agricultural fields and by decreasing application amount of fertilizers in agricultural fields." @default.
