| Popis: | The recent biological invasion of water hyacinth (Eichhornia crassipes (Mart.) Solms) into lakes and rivers of East Africa has forced the implementation of mechanical harvesting around key harbours and dams, resulting in subsequent difficulties of waste disposal. Utilization of these wastes would assist in deferring costs of control, currently covered by international agencies. This paper reports the nutrient contents, mineralization patterns and potential for ensiling water hyacinth wastes. Whole chopped plants and tissues separated into leaves, petioles and roots were placed into litter bags, deployed as surface mulch or submerged in water and recovered over 16 weeks. The wastes consisted of 45% leaves, 26% petiole and 29% roots and contained 92% moisture. Decomposition was greater under surface mulched conditions and significant differences were observed between plant tissues. The time to 50% decomposition of whole plants was 21 and 74 days for mulched and submerged conditions, respectively. M... |
