Ammonia (NH₃) reacts with nitric acid or sulfuric acid in the atmosphere and contributes to the formation of fine particulate matter. It is mainly produced by application of nitrogen fertilizer and livestock manure to the arable soil. Volatilization of NH₃ could decrease with application of acidic amendments such as iron sulfate (FeSO₄) through decreasing soil pH. This study was conducted to determine an optimum application rate of FeSO₄ to reduce NH₃ volatilization and maintain crop productivity in arable soil. Iron sulfate was applied at the rates of 0, 50, 100, and 200 ㎏ Fe ㏊<SUP>-1</SUP>. Cabbage (Brassica rapa L.) was planted on April 8<SUP>th</SUP> 2020 and harvested on June 10<SUP>th</SUP> 2020. The NH₃ gas was collected using static chamber (300 ㎜ in length and 120 ㎜ diameter) method. Cumulative NH₃-N volatilization decreased significantly with increasing application rate of FeSO₄. It decreased by ca. 21% at 200 ㎏ Fe ㏊<SUP>-1</SUP> of FeSO₄. Soil pH decreased significantly with increasing application rate of FeSO₄. A decrease in cumulative NH₃-N volatilization with FeSO₄ was mainly attributed to decrease in soil pH. Cabbage yield did not decreased with increasing application rate of FeSO₄. The maximum cabbage yield was 7.10 Mg ㏊<SUP>-1</SUP> and cumulative NH₃-N volatilization decreased by 10.2% from 28.4 ㎏ ㏊<SUP>-1</SUP> 63 days<SUP>-1</SUP> to 25.8 ㎏ ㏊<SUP>-1</SUP> 63 days<SUP>-1</SUP> with 110 ㎏ Fe ㏊<SUP>-1</SUP> of FeSO₄ application.
