This weed can withstand varied extreme environmental conditions in temperature, wind, humidity, illumination, acidity, alkalinity, and salinity. The probable means of combating its propagation and the various means of getting rid of this weed not proved much. This study investigated the potentials of E. crassipes in replenishing macronutrients specifically nitrogen, phosphorus and potassium (NPK) in a nutrient-depleted soil. Using an experimental study, water hyacinth was explored by comparing two conditions: i. the sundried compost; and ii. the fresh compost in soil. The composting lasted for 31 days, enough for the water hyacinth to decompose. The data gathered were then analyzed using single-factor analysis of variance (ANOVA). Results revealed that NPK improved from low to medium and high levels. Among sundried and fresh water hyacinth composts, there were significant effects in the nitrogen and phosphorous level in sundried treatment. Others do not have significant differences in NPK content before and after the composting, however all nutrient level means increased. Copyright@ International Science Community Association
