초록

농경지에서 발생되는 온실가스인 $CH_4$, $N_2O$의 배출제어 기술을 구명하기 위하여 수원시에 위치한 국립농업과학원 기후변화생태과 시험포장에서 온실가스 배출시험을 수행하였다. 고추밭에서 토성과 토양수분에 의한 온실가스배출 시험은 2004~2005년 2년간 고추 재배를 하여, 질소를 시용하지 않는 PK와 NPK+ 돈분퇴비 등으로 시비처리를 하였고 온실가스배출에영향을 주는 토양수분, 토양온도 그리고 무기태 질소($NH{_4}^+$, $NO{_3}^-$) 등 관련 요인별로 온실가스배출량을 측정하였다. 이와 같이 밭에서 온실가스 배출에 미치는 영향을 조사하여 온실가스 관리에 필요한 기초 자료로 활용하기 위해 시험한 결과는 다음과 같다. 1) 토성에 따른 $N_2O$ 배출량은 식양토에 비해 사양토에서 74.0~82.1% 적었고, 토양 수분장력 -30 kPa보다 -50 kPa에서 식양토는 13.2%, 사양토는 40.2%가 적었다. 2) $CH_4$ 배출은 식양토에 비해 사양토에서 45.7~61.6%, 그리고 수분장력에 따라 -30kPa보다 -50kPa에서 식양토 69.6%, 사양토 55.8%가 적었다. 3) $N_2O$ 배출에 영향을 미치는 요인은 식양토에서 무기태질소 (51.2%), 토양온도 (25.8%), 토양수분함량 (23.0%), 그리고 사양토에서는 토양수분함량 (39.3%), 토양온도 (36.4%), 무기태질소 (24.3%) 순으로 나타났으며, 식양토에 비해 사양토에서 $N_2O$ 배출에 대한 무기태질소의 기여도가 낮았다.

Importance of climate change and its impact on agriculture and environment has increased with a rise of greenhouse gases (GHGs) concentration in Earth's atmosphere, which had caused an increase of temperature in Earth. Greenhouse gas emissions such as methane($CH_4$) and nitrous oxide($N_2O$) in the field need to be assessed. GHGs fluxes using chamber systems in the fields(2004~2005) with pepper cultivation were monitored at the experimental plots of National Academy of Agricultural Science(NAAS), Rural Development Administration(RDA) located in Suwon city. $N_2O$ emission during pepper growing period was reduced to 74.0~82.1% in sandy loam soil compared with those in clay loam soil. Evaluating $N_2O$ emission at different levels of soil water conditions, $N_2O$ emission at -50 kPa were lowered to 13.2% in clay loam soil and 40.2% in sandy loam soil compared with those at -30 kPa. $CH_4$ emission was reduced to 45.7~61.6% in sandy loam soil compared with those in clay loam soil. Evaluating $CH_4$ at different levels of soil water conditions, $CH_4$ emission at -50 kPa was lowered to 69.6% in clay loam soil and 55.8% in sandy loam soil compared with those at -30 kPa. It implied that -50 kPa of soil water potential was effective for saving water and reducing GHG emissions. From the path analysis as to contribution factors for $N_2O$ emission, it appeared that contribution rate was in the order of mineral N(51.2%), soil temperature (25.8%), and soil moisture content(23.0%) in clay loam soil and soil moisture content(39.3%), soil temperature (36.4%), and mineral N(24.3%) in sandy loam soil.
