Abstract

본 연구를 통하여 우리나라 대표적인 농작물 47개의 탄소배출량을 산정하였다. 또한 농작물 생산 시 주요 요소로 투입되는 무기화학비료의 기여도 분석을 통하여 무기화학비료가 차지하는 탄소배출량을 정확하게 파악하였다. 농작물 중 시설감귤의 탄소배출량이 <TEX>$5.78E+00kg\;CO_2\;eq.\;kg^{-1}$</TEX>으로 47개 작물 중 가장 높았으며 시설포도 <TEX>$4.61E+00kg\;CO_2\;eq.\;kg^{-1}$</TEX>, 착색단고추 <TEX>$4.34E+00kg\;CO_2\;eq.\;kg^{-1}$</TEX>, 인삼 <TEX>$4.23E+00kg\;CO_2\;eq.\;kg^{-1}$</TEX>, 시설고추 <TEX>$4.04E+00kg\;CO_2\;eq.\;kg^{-1}$</TEX> 순으로 나타났다. 다음으로 농작물 1 kg 생산 시 발생하는 탄소배출량 중 무기화학비료의 기여도는 생산단계, 사용단계를 모두 포함하여 평균 25.19%를 차지하는 것으로 분석되었다. 정부의 정책, 정부 및 기업의 연구 개발을 통한 고품질 저탄소 비료 생산 보급과 같은 노력이 함께 이루어진다면 농업분야의 온실가스 감축에 큰 역할을 할 것으로 기대된다. Korea is currently underway research to estimate carbon footprint in agriculture centered on the RDA (Rural Development Administration). This study was estimated carbon footprint for major 47 crops. In addition, contribution of inorganic chemical fertilizers, main elements for production of crops were analyzed. The carbon footprint of <TEX>$5.78E+00kg\;CO_2\;eq.\;kg^{-1}$</TEX> for citrus fruit in greenhouse was highest, grape in greenhouse, sweet pepper in greenhouse, ginseng, green pepper in greenhouse were followed by <TEX>$4.61E+00kg\;CO_2\;eq.\;kg^{-1}$</TEX>, <TEX>$4.34E+00kg\;CO_2\;eq.\;kg^{-1}$</TEX>, <TEX>$4.23E+00kg\;CO_2\;eq.\;kg^{-1}$</TEX>, <TEX>$4.04E+00kg\;CO_2\;eq.\;kg^{-1}$</TEX> respectively. Next, production phase contribution of inorganic chemical fertilizer to carbon footprint of crop 1 kg were analyzed mean value 1.88%, 9.06% for single fertilizers and complex fertilizers respectively. And use phase accounted for mean value 14.24%. Therefore, to reduce the fertilization of inorganic chemical fertilizer will be reduced <TEX>$CO_2$</TEX> from crop production, also greenhouse gas emissions of agricultural sector will be reduced.
