초록

본 연구에서는 벼 재배 부문 질소 비료 시용에 따른 N2O 배출량 평가를 위해 경기도 화성시 경기도농업기술원 내 벼논에서 폐쇄형 챔버법으로 측정하였으며, 미량의 N2O 배출량이 과소평가되지 않도록 현장 측정 플럭스 자료에 대한 방법검출한계(MDL; Method Detection Limit)와 실용정량한계(PQL; Practical Quantitation Limit)를 산정하고 이를 바탕으로 QA/QC 방법을 설정하여 원시자료와 QA/QC 방법을 수행한 N2O 배출량을 비교하였다. 벼 재배 표준시비량인 3요소 N-P2O5-K2O = 90-45-57 kg ha-1 기준 질소 0배, 1배, 1.5배, 2배로 4처리하여 평가한 N2O 배출량 변화에서는 N2O 배출량이 가장 적었던 질소 0배 처리구 외에는 원시자료와 QA/QC 방법을 수행한 자료 모두 유의한 차이가 없었으며, 질소 비료 시용량이 많을수록 N2O 배출량이 높게 나타나 질소 1배 처리구 대비 질소 2배 처리구는 191% 높게 나타났다. 질소 시비량에 따른 N2O 배출량의 회귀관계 분석에서는 지수회귀모형에서 결정계수가 가장 높았으며, 선형회귀모형으로 산정한 기본배출계수는 IPCC에서 제공하는 기본배출계수 값과 동일하게 나타났다. 본 연구결과는 농업부문 온실가스 배출량 산정을 위해 보편적으로 사용하고 있는 폐쇄형 챔버법의 플럭스 자료에 대한 QA/QC 방법을 제시하고, 원시자료와의 비교분석을 통해 질소 비료 시비에 따른 벼논에서 발생하는 N2O 배출량에 대한 신뢰성 있는 평가가 가능한 것으로 판단할 수 있다.

In order to accurately calculate greenhouse gas emissions in the agricultural field, Korea has been developing national-specific emission factors through direct measurement of gas fluxes using the closed-chamber method. In the rice paddy, only national-specific emission factors for methane (CH4) have been developed. It is thus necessary to develop those for nitrous oxide (N2O) affected by the application of nitrogen fertilizer. However, since the concentration of N2O emission from rice cultivation is very low, the QA/QC methods such as method detection and practical quantification limits are important. In this study, N2O emission from a rice paddy was evaluated affected by the amount of nitrogen fertilizer, by taking into account both method detection and practical quantification limits for N2O concentration. The N2O emission from a rice paddy soils affected by the nitrogen fertilizer application was estimated in the following order. The method detection limit (MDL) of N2O concentration was calculated at 95% confidence level based on the pooled standard deviation of concentration data sets using a standard gas with 98 nmol mol-1 N2O 10 times for 3 days. The practical quantification limit (PQL) of the N2O concentration is estimated by multiplying 10 to the pooled standard deviation. For the N2O flux data measured during the rice cultivation period in 2021, the MDL and PQL of N2O concentration were 18 nmol mol-1 and 87 nmol mol-1, respectively. The measured values above the PQL were merely about 12% of the total data. The cumulative N2O emission estimated based on the MDL and PQL was higher than the cumulative emission without nitrogen fertilizer application. This research would contribute to improving the reliability in quantification of the N2O flux data for accurate estimates of greenhouse gas emissions and uncertainties.
