Response to Ammonia Emission Flux to Different pH Conditions under Biochar and Liquid Fertilizer Application

For the ammonia generated in Korea, contribution rate of livestock manure is high, and a large amount (NH3) emitted into atmosphere during soil application process. Volatilization NH3 affected by characteristics as well characteristics, but current inventory does not sufficiently reflect this. This study was conducted to confirm change from liquid fertilizer (LF) due pH evaluate impacts biochar (BC) on suppression volatilization. Estimating emission flux using chamber for 24 soils after LF treatment, it showed tendency increase exponentially increased 4 7. In addition, parallel treatment BC pH, thereby increasing flux. The rise temporary phenomenon that appears early stage, since volatilization also highest at beginning application, effect factor its should be considered when calculating emissions. Therefore, follow-up studies such subdividing enhancing developing reduction coefficient certify are needed.
