초록
토양 유기물함량이 다른 감귤원 토양 19개 토양통에서 30개의 토양시료를 채취하여 8개 농약에 대한 흡착특성을 분석하였다. 흡착형태 alachlor와 chlorpyrifos는 C형, diuronn과 diniconazole은 L형, metribuzin, metolachlor 및 linuron은 유기탄소 함량이 증가함에 따라 S, C 및 L형이 복합적으로 나타났으며, chlorothalonil은 유기탄소 함량에 따라 C, S, L 및 H형이 모두 나타났다. metribuzin, metolachlor 및 alachlor의 분배계수 값은
This study was carried out to determine the adsorption characteristics of eight pesticides on thirty citrus orchard soil so soil samples were taken from nineteen soil series containing different fractions of organic carbon(Foc). The adsorption characteristics for eight pesticides fitted to Freundlich isotherms. The adsorption isotherms showed C-type for alachlor and chlorpyrifos, L-type for linuron and diniconazole. and S, C, and L-types for metribuzin, metolachlor, and alachlor with increasing Foc, respectively. In particular, the adsorption of chlorothalonil showed S, C, L, and H-types with increasing Foc. Distribution coefficient(Kd) values of metribuzin, metolachlor, and alachlor were below
