Abstract

Applications of plant residues and green manures generally improve the properties of soil under conventional farming system. Therefore, we investigated the improvement of selected soil physical properties, bulk density, porosity, and water content, soil penetration resistance, and soil microbial biomass carbon (SMBC) content as affected by different management practices: 1) conventional tillage without rice straw or green manure crop treatment (TNT, check plot), 2) no-tillage amended with rice straw (NTRS), 3) no-tillage amended with rye (NTR), 4) no-tillage amended with Chinese milk vetch (NTCMV), 5) no-tillage without rice straw or green manure crop treatment (NTNT), The values of bulk density, porosity, and water content ranged from 1.22 to 1.37 Mg $m^3$, from 48.3 to 54.0%, and from 35.0 to 40.2%, respectively. The management practices might positively influence the changes in the selected soil properties, especially in the second experimental year. The soil penetration resistance and SMBC content were also improved after applying rice straw and green manure crops as comparing with TNT. Therefore, applications of the rice straw and green manure crop management practices under no-tillage system positively influenced soil physical properties and soil microbial activities in paddy field.

벼 유기농업은 한국에서 빠르게 확산되고 있다. 유기재배에서 벼 생육은 토양 물리적 특성과 토양 미생물의 기능에 크게 의존한다. 본 연구는 무경운 답에서 유기농업을 위하여 토양 물리성과 미생물 생체량에 미치는 녹비작물의 효과를 검토하였다. 시험구는 무경운, 무경운+볏짚, 무경운+호밀, 무경운+자운영 그리고 경운구를 3반복으로 죽곡통에서 2005년 5월에서 2006년 10월까지 수행하였다. 경운구는 2005년과 2006년 모두 토양 가밀도가 가장 높은 반면 공극률은 가장 낮았다. 무경운+호밀 처리구는 공극률이 가장 높았으며 무경운 처리구의 표토 관입저항은 경운구 보다 낮았다. 담수 전 2005년과 2006년 토양 미생물 생체량 탄소 함량은 무경운+자운영 처리구가 477 mg $kg^{-1}$ 및485 mg $kg^{-1}$으로 가장 높았고 무경운+호밀 처리구는 413 mg $kg^{-1}$ 및 484 mg $kg^{-1}$였으며 경운 처리구는 363 mg $kg^{-1}$ 및 445 mg $kg^{-1}$을 나타냈다. 시기적으로 토양 미생물 생체량 탄소 함량은 유수형성기에 낮아지는 경향이었다. 연구결과 녹비작물을 시용한 무경운 재배기술은 경운에 비해 토양 공극률과 토양 미생물 생체량 탄소 함량을 크게 개선하였다.
