Abstract : Preliminary results based on 2 years of monitoring at most sites indicate that time lags between saturation and iron reduction range from several days to several weeks, depending upon temperature and other factors. Growing seasons based on measured soil temperatures often differed considerably from approximations based on air temperatures and soil temperature regime regions. Due to annual variability, longer monitoring periods are needed to identify reliable hydric soil indicators.
