Influence of N Fertilization Level, Rainfall, and Temperature on the Emission of N₂O in the Jeju Black Volcanic Ash Soil with Soybean Cultivation

Nitrous Oxide Emissions from Red Pepper, Chinese Cabbage, and Potato Fields in Gangwon-do, Korea

“…Emission factor of N2O calculated from accumulated N2O emission and nitrogen fertilization rate for each crop and background N2O emission ranged from 0.00545 to 0.00676 kg N2O-N kg -1 N for red pepper, from 0.00541 to 0.00800 kg N2O-N kg -1 N for potato, from 0.00405 to 0.00483 kg N2O-N kg -1 N for Chinese cabbage cultivated in spring, and from 0.00226 to 0.00387 kg N2O-N kg -1 N for Chinese cabbage in fall (Table 2). Nitrous oxide emission factors from black volcanic ash soil in Jeju island were 0.0202 kg N2O-N kg -1 N for soybean (Yang et al, 2012a), 0.0025 kg N2O-N kg -1 N for carrot (Yang et al, 2012b), and 0.0040 kg N2O-N kg -1 N for potato (Yang et al, 2012c). In Japan, N2O emission factor is 0.0062±0.0045 kg N2O-N kg -1 N because of 0.0032 kg N2O-N kg -1 N for well-drained upland and 0.0140 kg N2O-N kg -1 N for poor-drained upland (Akiyama et al, 2006).…”

“…Collection and analysis of nitrous oxide Gas samples were collected using static chambers, the most commonly used tools worldwide for the greenhouse gas research (Kim et al, 2006;Kim et al, 2008;Saggar et al, 2009;Kim et al, 2010;Seo et al, 2012;Yang et al, 2012a;Yang et al, 2012b;Yang et al, 2012c), twice a week from just after transplanting the crops to next growing season in the following year. Parkin (2008) reported that gas sampling at 1-4 days intervals resulted in cumulative N2O emissions with a precision of ±10% compared with ±14% for 3-7 days intervals.…”
