초록

본 연구는 벼 재배 장기연용 시험포장에서 다른 특성의 토양개량제 사용이 벼(Oryza sativa) 생산량, 토양 가용성 탄소, 질소함량 및 탄소 저장량 변화에 미치는 영향을 평가하고자 하였다. 본 시험에 사용된 처리구는 NPK 처리구, NPKS 처리구(NPK+규산), NPKL 처리구(NPK+생석회), NPKC 처리구(NPK+볏짚퇴비)를 장기연용 포장에서 선별하여 실험을 진행하였다. 1995년 처리구 간의 유의한 벼 수량 차이 없었으나, 2019년 NPKL, NPKC 처리구 벼 수량은 NPK 처리구보다 각각 4.3%와 14.3%씩 증수되었다. 2019년 NPKS와 NPKL 처리구의 토양 pH는 각각 6.7과 6.4였고, 시험 전 토양 pH (5.2)보다 증가하였다. 시험 전과 비교할 때, NPK, NPKS 및 NPKL 처리구의 토양 유기물 함량은 통계적으로 유의적인 차이를 나타내지 않았으나 NPKC는 1995년과 2019년에 각각 34 g/kg, 27 g/kg으로 증가하였다. 토양의 가용성 탄소 및 질소 함량은 2019년의 NPKS 및 NPKL 처리구에서 1.1에서 1.9배 가량 증가하였다. 이러한 결과를 종합하여 벼 재배시 토양개량제 사용은 재배전 토양검정을 통해 토양의 특성을 파악하여 사용하는 것이 생산량 증대와 더불어 농업환경을 고려한 토양관리방법이라고 판단된다.

This research evaluated the long-term application effects of different soil amendments on yield, dissolved organic carbon, nitrogen and soil organic carbon stock in rice paddy. The experiment consisted of four different fertilizations; Inorganic fertilization (NPK), NPK+Lime (NPKL), NPK+Silicate (NPKS), NPK+Compost (NPKC). There was no significant difference in rice yield between the treatment groups in 1995, but the rice yields in the NPKL and NPKC treatments in 2019 increased by 4.3% and 14.3% compared to NPK. In terms of soil properties, the pH of NPKS(6.7) and NPKL(6.4) in 2019 increased the most compared to the soil pH before experiment(5.2). The organic matter(OM) content from NPKC treatment increased upto 34 and 27 g kg-1 in year of 1995 and 2019, respectively, compared to before the test. In NPKS and NPKL treatment, labile carbon and nitrogen content, used as a soil quality indicator, increased by 1.1-1.9 times over the control. From these result, it is suggested that type and application rate of soil amendment should be determined based on the soil analysis before cultivation for sustainable agricultural environment and productivity.
