Analysis of variance summary of the effects of rice cultivar, pre-assigned water management (WM) practice, and their interaction on soil physical and chemical properties from the top 10 cm of a Dewitt silt loam prior to flood establishment at the Rice Research and Extension Center near Stuttgart, Arkansas during the 2015 growing season. Overall means (n = 16) and standard errors (SE) are also reported.
