| migration of (14)c in the paddy soil-to-rice plant system after (14)c-acetic acid breakdown by microorganisms below the plow layer. | migration of (14)c derived from (14)c-acetic acid was examined by using soils sampled from paddies in four administrative areas in japan (aomori, yamanashi, ehime and okinawa) and rice plant in a tracer experiment to understand the fate of (14)c in the paddy soil-to-rice plant system. the loss of (14)c radioactivity levels derived from (14)c-acetic acid was caused by soil microorganism breakdown. a part of the (14)c fixation to soil was caused by microbial assimilation into the fatty acid fracti ... | 2010 | 19896253 |
