Water Hyacinths as a Resource in Agriculture and Energy ...

The water hyacinths have a C/N ratio of about 16 according to Abdelhamid and Gabr (1991), whereas Dalzell et al. (1979) report a C/N ratio of 20. This means that water hyacinths need an addition of cellulose material, such as leaves (C/N 60.8, Polprasert et al., 1980) to keep the ammonia losses low for the microbial decomposition. 3.6.4.
