N2  - I n this study water hyacinth a nd solid waste were mixed at the  different rati os and were converted to soil conditioner or  fertilizer by composting process. Bacterial seeding was added to  accelerate the maturation t ime.  Th e experime nts were conducted i n Vietnam and in Thailand. The  mode of composting process in Vietnam was Chinese ground- surface  aerobic composting and ratio of water h yacinth to solid waste was  4: 1 with bacterial seeding 0 . 01596 of dry weigh t. Experiment in  Thailand was undertaken by forced aeration mode of composting. It  comprised of two runs. In run 1 ratios of water hyacinth to solid  waste in three piles were as followed: pil e 1 = 4:1, pile 2 = 3:2,  pile 3 = 2:3 and bacterial seeding of three pil es was 0.015%. After  obtaining t h e optimal ratio of water hyacinth to solid waste run 2  was carried out with that ratio and diff erent size of bacte rial  seeding. Pile 4 = 0.010%, pile 5 = 0.015%, pile 6 = 0 . 025%.  The resul ts s howed that time required for composting process  to reach maturation time was much l onger i n Ch i nese ground- surface  aerobic composting pile than in forced aeration p iles. Optimal  water h yacin t h to solid waste was 4:1 and bacterial seed i ng sizes  from 0.010% to 0.025% gave a lmost the same acceleration rate of  mat ura t ion t ime. Final compost product can be served as soil  conditione r.  Further investigation about op timal water hyacinth to solid  waste ratio oth e r than those in t h is study would be recomme nded.  The time required for composting process in Chinese ground- s u rface  aerobic composting pile in different seasons in Vietnam should be  studied
