Rice is Nice

According to the University of Arkansas parboiled rice hulls can be used effectively as a pine bark substrate.  They looked at spirea growing for one and two seasons long and measured the growth.  Their research proved that up to 40% of the pine bark can be substituted without having decomposition.  Growth was not reduced and irrigation remained the same.  For more information visit Nursery Management June 16, 2011.  http://www.nurserymanagementonline.com/researchers-study-parboiled-rice-hulls.aspx?
