Elution Patterns of Anions in Multi-layered Soils amended with Cow Manure Compost
우분퇴비 처리에 따른 다층구조 토양내 음이온의 용출특성 변화
Abstract
To investigate the effects of cow manure compost(CMC) on soil and water environment as non-point source, the elution patterns of anions were determined in muti-layered soil columns which were consisted of one top and one bottom in combination. The top soil columns were uniformly packed with Ap horizon soils amended with air-dried CMC at different ratios(0, 2, 4, 6%, wt/wt), the bottom ones were packed with of B horizon soils of 15, 30, and 45cm in length. After saturating the each soil column, the leachate were collected from the bottom of the column while the double-ionized water was applied from the surface of the column by constant head method. From the hydraulic conductivity and anion eluted were measured in the leachate. Each saturated hydraulic conductivities for top and the bottom soils were 3
비점오염원으로 토양과 수환경에 영향을 미치는 우분퇴비의 영향을 조사하기 위하여 상부와 하부에 연결한 다층토양칼럼을 가지고 음이온의 토양으로부터 용출경향을 조사하였다. 상부 칼럼은 건조 우분 퇴비를 0, 2,4, 6%의 비율로 Ap토양에 처리한후 균일하게 채웠고 하부칼럼은 15, 30, 45cm의 길이의 아크릴칼럼에 B층 토양을 용적비중 1.3g/
