The land application of treated swine waste water (TSWA) contains abundant amounts of nutrients and water for crop uptake. The objectives of this study are to monitor the effects of land application of TSWA, applying 100 mm per year in the treated plots and chemical fertilizer in the control plots, on the soil quality, crop quality, and quality of surface and groundwater. The two experimental sites were selected from Taiwan Livestock Research Institute (TLRI) site and Lutsao site monitoring from January 2003 to October 2003. Lysimeter experiments in TLRI plot and pot experiments in Wangdan plot of Taiwan Sugar Company were also carried out in 2003. The results from the monitoring system in 3 years, indicated that surface water quality, groundwater quality, soil basic properties including pH, electric conductivity (EC), exchangeable bases, organic C, available P, Cu, and Zn of rural soils in treated plots are almost no significant differences compared with those of control plot which without application of TSWA on two experimental sites (p＞0.05). The results also indicated that there are no significant differences between macro elements (N, P, K, Ca, and Mg) and microelements (Fe, Mn, Cu, and Zn) in crop quality and productivity of sugarcane, pangolagrass and napiergrass pasture (p＞0.05) during 3 years. Pot experiments indicated that the concentration of N, P, K, Cu, and Zn in sugarcane, grass, and vegetables growing in the soils irrigated TSWA are no significant differences compared with those of applying chemical fertilizer. There are also no significant effects on the accumulation of Cu and Zn in the soils and sugarcane or pangola grass after three times of application of TSWA in two sites. The results from this three years monitoring system in the two field sites can provide a safe, recycling, and managing system to recycle the water and nutrients from TSWA and can be evaluated for revising the regulation of land application of TSWA, which were newly announced by Taiwan EPA in July, 2003.畜產處理排放水土壤處理氮磷銅鋅污染監測井甘蔗牧草蔬菜地下水livestock treated waste watersoil treatmentnitrogenphosphoruscopperzincpollutionmonitoring wellsugarcanepasture grassvegetablesgroundwater
