A model of TIN infiltration in sandy soil paddy fields was developed in this paper. It incorporates TIN uptake of fertilizer by paddy, denitrification, plankton growth, soil adsorption and desorption of fertilizer in paddy fields, decomposition of paddy litter, plankton and organic material in soil. The results calculated from the model were in good agreement with the measured values, which demonstrated that the model was useful in predicting the infiltration and runoff of TIN in paddy fields.<br>Runoff loading was derived from the model simulation (from Jun. 15 to Sep. 30). The infiltration loading was 3.06 g·m<sup>-2</sup>, which was about 30.5% of the total amounts of input feritilizer (10.3 g·m<sup>-2</sup>) for paddy.
