We have examined the effect of rice straw mat (RSM) on the reduction of non-point source (NPS) pollution loads at soybeancultivations. The slope of the experimental plot was about 3 %. Monitoring was carried out for four years at conventional tillage (CT)in 2008～2009 years and RSM covered tillage in 2010～2011 years. Thirty-two rainfall events were monitored and analyzed duringthe study period. During the 2 years of 2008 and 2009, 20 rainfall runoff events were monitored. But in 2010 years, only 2 rainfallrunoff events could be monitored. And in 2011 years, 10 rainfall runoff events was monitored. It was because the RSM coverenhanced infiltration and reduce runoff in 2010 and 2011. Average NPS pollution load (organic matters) of the RSM covered fieldwas reduced by 72.1～94.2 % compared to that of CT field. NPS pollution load of TN and TP reduced by 67.5 % and 55.7 %,respectively. Especially, SS pollution load was reduced by 97.3 %. Based on the results, rice straw mat cover was considered as apromising best management practices (BMP) to reduce NPS pollution load. However, it was recommended that the results are limitedto the field conditions and the same experiments must be performed on different soil textures, slopes, and crops if it is applied tothe development of policies.
