Recently, biomass power plants are increasing as an alternative energy source to reduce the carbon emissions from fossil fuels. The amount of waste increases and bottom ash is generally buried in soil. However, there little research on dissolution characteristics nitrogen, a macronutrient soil, using (BA). To evaluate nitrogen soil with BA, we mixed BA collected leachate for 5 weeks, measured NH4+-N NO3--N concentration leachate. As results, reduced leaching by up 18% 38%, respectively. decrease judged be result increased adsorption due high pH ash, these results often confirmed other biochar. also decreased, but it not related capacity so further needed. These suggested that reduces contents effluent, which can used important indicator soil.The plant (average standard deviation; 3 replicate). (left) Accumulation NH4+-N; (right) NO3--N.
