Recently, biomass power plants are increasing as an alternative energy source to reduce the carbon emissions from fossil fuels. The amount of waste from biomass power plants increases and bottom ash is generally buried in soil. However, there is little research on the dissolution characteristics of nitrogen, a macronutrient in soil, using bottom ash (BA). To evaluate nitrogen dissolution in soil with BA, we mixed BA with soil, collected leachate for 5 weeks, and measured NH₄<SUP>+</SUP>-N and NO₃<SUP>-</SUP>-N concentration in leachate. As a results, BA reduced the leaching of NH₄<SUP>+</SUP>-N and NO₃<SUP>-</SUP>-N by up to 18% and 38%, respectively. The decrease of NH₄<SUP>+</SUP>-N leaching is judged to be the result of increased NH₄<SUP>+</SUP>-N adsorption due to the high pH of the bottom ash, and these results are often confirmed in other biochar. The NO₃<SUP>-</SUP>-N leaching also decreased, but it is not related to the adsorption capacity of BA, so further research is needed. These results suggested that BA reduces the contents of NH₄<SUP>+</SUP>-N and NO₃<SUP>-</SUP>-N in the soil effluent, which can be used as an important indicator for using bottom ash in the soil.
