Table 2

Analysis of variance summary of the effects of previous crop, cultivar, time, and their interaction on methane (CH₄) fluxes from flooding to flood release and following flood release from a clay soil during the 2013 growing season at the Northeast Research and Extension Center in Keiser, Arkansas.
