Abstract

Nutrients were investigated for surface water and ground water of paddy field and upland in a rural watershed from May 2008 to January 2009. The cocentrations of TN and $NO_3-N$ in ground water higher than those in surface water due to fertilization on cabbage upland neighboring a river during May to September, but lower than those in surface water during October to January. However, the concentrations TP and $PO_4-P$ in ground water were lower than those in surface water. TP and $PO_4-P$ concentrations in ground water of paddy field were generally lower than those of upland.
