Abstract

Two kinds of plant growth media were made by sintering the sludge dredged from Tagonoura Bay (SM medium) and the mixing materials of the sludge and glass powder (GM medium). Rose plants were hydroponically grown with the sintered materials for 21 months. Trace elements in the media, elutions and rose leaves, and gas concentration in the media were analyzed. Temperature of the media and pH and EC in the solution were also measured. Rose flower stalks were harvested 7 times (about 30 stalks in each harvest) during the experimental period.<BR>The length and quality of the flower stalks were comparable in the SM medium with the Rockwool medium, but lower in the GM medium. Trace element analysis of the elutions of the sintered materials showed that the concentrations of the elements were lower than the toxic levels reported before. The nutrient solutions passing through the GM medium had a lower pH (about 5) on days 468-593 during the experimental period. The EC, medium temperature and gas concentration do not seem to have any significant effect on rose growth.<BR>From this experiment, it became clear that the SM medium is suitable for the rose culture. The rose growth anomalies in the GM medium might be related to a decrease in PH in the nutrient solution passed through the medium but the cause could not be clarified.
