초록
본 연구는 황 원소를 이용하여 시설재배지의 일부 토양에서 나타나는 알칼리 반응을 교정하고자 실시하였다. 황 원소의 산화와 토양 pH에 미치는 효과를 살펴보기 위하여 토양 pH 8.3을 6.3으로 낮추는데 소요되는 황 시용량을 완충곡선으로부터 계산하여 황 소요량의 1~10배 수준까지 첨가하고 50% water holding capacity에 해당하는 수분을 가한 다음,
To determine application rate of elemental sulfur to adjust pH of alkaline soil, buffer curve method was investigated. The elemental sulfur required to control pH 8.3 to pH 6.3 by buffer curve calculation was treated in two soils of silty loam and sandy loam, and the sulfur-mixed soils were moistened with 50% of water holding capacity during incubation of 6 weeks at
