The objective of this study was to investigate the nutrient load balance in the reservoir irrigated paddy block during growingseasons. Idong reservoir irrigation paddy block of 10.3 ha in size was selected to collect hydrologic and water quality data.
Irrigation, canal flows, and paddy field drainage were measured using a water level gauge, while water samples were collected andanalysed for water quality. The water balance analysis showed that 81 % and 75 % of total outflow were through paddy andirrigation canal drainage during 2011 and 2012, respectively. The water quality of paddy field drainage varied greatly depending onrice cultivation stage ranging from 0.05 to 24.55 mg/L and from 0.01 to 0.76 mg/L for T-N and T-P, correspondently. Paddy fielddrainage loads during May through June account for 64 % and 76 % in 2012 and 2013, while 82 % and 81 % for T-P in 2011and 2012, respectively. The Pearson correlation analysis showed that rainfall was significantly correlated with nutrient loads duringJuly through August due to runoff, and irrigation was related with nutrient loads of drainage during some period of July throughSeptember due to irrigation return flow. This study results showed characteristics of inflow and outflow nutrient loads from plentifulirrigated paddy block.
