| Research Abstract |
The objective of this study was to evaluate the effects of charcoals addition on NO^-_3 transport in soils from batch experiments and soil column experiments. The results were as follows : (1) Application of bagasse-charcoal at higher pyrolysis temperature (700-800℃) to the Shimajiri-Maji soil is a viable option for the reduction of NO^-_3 leaching to groundwater. (2) NO^-_3 was temporarily adsorbed by bagasse-charcoals and easily desorbed by infiltration process.
