“…Therefore, when composting water hyacinth, cellulose-rich substances such as leaves (C/N 60.8) must be added in order to reduce ammonia loss. According to Elserafy et al [42], the optimum moisture content for compost is 60%, and the optimal range given by Dalzell et al [41] is 50-60%. Selection of composting sites is also critical, and the composting can be carried out in deep pits or stacks.…”

Abstract:The unchecked growth of Eichhornia crassipes can cause significant harm, including covering of the water surface, depletion of oxygen, clogging of river channels, and promotion of the breeding of flies and mosquitoes. These effects can significantly impact farmland irrigation, water transportation, and human health. However, methods for controlling its growth are not ideal, and control using biological and chemical agents can result in secondary pollution. The utilization of E. crassipes as a resource, for example, as animal feed or organic substrates, can not only turn waste into valuable resources, but it can also solve the problem of its growth, thus bringing about economic and ecological benefits. In this paper, the growth and ecological characteristics of E. crassipes, its nutrient composition, and resource utilization approaches were reviewed. The challenges associated with the large-scale utilization of E. crassipes were also analyzed in order to provide references for the control and resource utilization of the species. Regarding challenges such as the difficulty of cultivation and the high cost of harvesting and dehydrating, it is necessary to investigate the proper water surface and coverage characteristics of E. crassipes cultivation to assure adequate biomass and protect the ecological landscape. It is also necessary to evaluate the effect of E. crassipes cultivation on the health of aquatic ecosystems and the safety of the water environment in order to prevent the significant potential ecological and environmental risks. In addition, developing portable, high-efficiency facilities to promote the effectiveness of harvesting, transportation and dehydration are needed, as well as further improvement in the techniques of utilization and assessment of the economic value.

“…(Malik, 2007). It is reported that water hyacinth seems to be a good source of organic carbon and has been used as an organic fertilizer (Oroka, 2012;Elserafy et al, 1980). There have been positive responses reported for water hyacinth compost on growth and yield of Brassica juncea (green mustard cabbage) (Nuka and Dubey, 2011) and Celosia argentea L (Lagos Spinach) (Sanni and Adesina, 2012).…”

“…The preparation of water hyacinth (Eichornia crassipes) compost and chemical analysis of the composted materials over the rotting period have been reported in part I of the present study (4). Samples of the composted materials were brought to the laboratory over the rotting period and humic substances were extracted using 0.1 M Na'P207-O.1 M NaOH solution as described by SONBOL and ELARQUAN (9).…”
