Note
In situ rates of waterhyacinth decomposition were found to vary with tissue nitrogen and fiber content. High nitrogen (2.8%), low fiber (49%) waterhyacinth aerial tissues collected from a eutrophic site decomposed more rapidly than low nitrogen (1.3%), high fiber (58%) aerial tissues collected from a nutrient-poor site. In addition, waterhyacinth roots (65% fiber) decomposed much more slowly than aerial waterhyacinth tissues (49% fiber).
