This research was conducted to investigate the changes in soil chemical properties of root media as influenced by incorporation rate of a polyacryl amide hydrogel, Stocksorb C. The pH at 5 weeks after treatment in four root media such as peatmoss + vermiculite (1:1, v/v; PV), peatmoss + composted rice hull (1:1; PR), peatmoss + composted saw dust (1:1; PD) and peatmoss + composted pine bark (1:1; PB) containing STSB were in the range from 7.04 to 7.30, which was too high. Elevated incorporation rate of STSB resulted in increase of EC in soil solution of four root media with linear and quadratic response. The concentrations of $NH_4^+-N,;NO_3^--N,;PO_4-P^{3-},;K^+,;Ca^{2+}and;Mg^{2+}$ in four kinds of root media increased as incorporation rates of STSB were elevated. But the $NO_3^-$-N concentrations in PS media were lower than those in other there root media tested. The Fe concentrations in PV, PR and PS media increased as incorporation rates of STSB were elevated, but those in PB medium did not show significant different. The concentrations of $Fe^{2+},;Mn^{2+},;Zn^{2+}and;Cu^{2+}$ in PS media were higher than those in other three root media.
