Abstract
本試驗之目的為測定施灌豬場排放水對盤固草地不同土壤滲漏水質之影響。本試驗採用2種砂質壤土、1種壤土及1種坋質壤土等4種土壤，三重複之完全逢機設計。施灌期間為自2002年9月至2003年2月，將308 kg N/ha之排放水分次施灌。本試驗以自來水淋洗方式，取得根系層1m之滲漏水，並分析滲漏水之水質。由試驗結果得知，四種土壤滲漏水之NO_3^--N濃度不超過10 mg/L；DP（dissolved phosphorus）不超過0.60 mg/L；電導度不超過1.05 dS/m。TN（total nitrogen）及TP（total phosphorus）經由滲漏水而損失之百分率不超過1%。由本試驗結果之建議，以分次灌溉豬場排放水於盤固草地，可降低豬場排放水對地表水及地下水之污染。惟長期施灌豬場排放水對土壤滲漏水質之影響乃需繼續監測。
The purpose of this study was to investigate the effects of treated swine wastewaster on percolation water quality from pangolagrass plots using different soils. Four soil textures and three replications with complete random design was used. The treated wastewater with a 308 kg/ha nitrogen load rate was applied to pangolagrass plots from September 2002 to February 2003 during the dry season in Southern Taiwan. Using tap water to leach the soil nutrients, percolation water was collected from a 1 m soil depth in the middle of February. The results showed that the nitrate nitrogen concentrations from percolation water in four soil types was less than 10 mg/L; dissolved phosphorus less than 0.60 mg/L; electrical conductivity less than 1.05 dS/m. The percentages of mean total nitogen and total phosphorus loss for treated swine wastewater from percolation water was less than 1%. The results from this study suggests that treated swine wastewater application to pangalagrass pastures with split irrigation can reduce the potential surface and groundwater pollution. However, the long-term effects of groundwater quality for the soil receiving treated swine wastewater needs to be monitored.
