The efficacy of the natural amendments in improving physical condition as well as waterretention characteristics of the growing media in pot culture was studied on seven different mixratio of growing media applied to soil. Growing media was prepared from peat, perlite, pruningwaste, pulp(3:1:3:3(w/w/w/w)). Growth substrates were prepared by mixing growing media at therates of 0%, 10%, 20%, 30%, 40%, 50% and 100% with soil at 100%, 90%, 80%, 70%, 60%,50% and 0%, respectively. The bulk density tended to decreased with increasing growing mediaproportions. The particle density was lowest(0.6 g/cm3) in sole growing media treatment and theporosity of all the soil mixed growing media(63.2~83.3%) was significantly higher than that ofthe soil as sole medium(60.7%). The water content was lowest in sole soil treatment(5.1%) andgrowing media as sole medium(57.8%) was the closely ideal range for pot culture(>60%). Although substrates were varying water to the atmosphere at similar rates which retained waterfor longer, growing media as sole still remain constant on high water content. It was confirmedthat strongly correlated between bulk density and water retentivity(correlation-0.85).
