The Saemangeum reclaimed land has many exposed areas due to the lack of vegetation, and then fugitive dust may be generated by strong winds. To reduce such fugitive dust, barley and reed were tested by various soil management practices (sowing time, irrigation water salt concentration, fertilizer type, fertilizer application method). Summarizing the results are as follows; Wind speeds in the Saemangeum Gwanghwal area in Gimje tend to increase in January - April, decrease in May - August, and slightly increase again in September - December. In particular, strong winds in this area concentrated on March - April. Therefor, it is important to cover the soil surface in March - April. In the first period (April.24 - May.6, 2020) of collecting fugitive dust according to the salt concentration of irrigation water during barley cultivation, 0 dS m<SUP>-1</SUP> and 3 dS m<SUP>-1</SUP> treatment were statistically significant than 6 dS m<SUP>-1</SUP> treatments. However, there was statistically no significant in the 2<SUP>nd</SUP> periods (May.12 - June.28, 2020) and 3<SUP>rd</SUP> periods (June.28 - July.17, 2020) due to the weak wind speed. The effect of reducing fugitive dust by sowing period of barley was statistically significant in the first periods (April.24 - June.6) compared to June and August when the sowing in February, April, October, and December. The 2<SUP>nd</SUP> periods (April.12 - June.28) and 3<SUP>rd</SUP> periods (June.28 - July.17) were also statistically significant compared to the sowing in June and August. And, crop growth by fertilizer type, ammonium sulfate fertilizer treatments (ammonium sulfate, fused super phosphate, potassium sulfate) with sulfate root was better than that of urea treatment (urea, fused phosphate, potassium chloride), even if there was no statistical significance. Between the fertilizer treatment methods in the second periods, soil/soil (basal dressing/top dressing) and soil/foliar had statistically significant compared to foliar/foliar. The effect of reducing fugitive dust between fertilizer types and treating fertilizer methods in reeds was statistically not significant.
