| dissolved organic matter from agricultural fields in the irrigation period. | the aim of this study was to quantify and characterize the dissolved organic carbon (doc) of paddy fields and crop fields in tottori, japan. dissolved organic carbon (doc) and ultraviolet (uv) absorbance was measured for the filtrated water of each samples. doc concentration and suva (specific uv absorbance) of biodegradation analysis samples were determined around 50 days after the incubation. in the fukui paddy fields, doc concentration varied seasonally from 1.1 to 10.1 mg.cl(-1), showing hig ... | 2005 | 16477991 |
