    Water hyacinth is a common fodder plant in the third world especially Africa though excessive use can be toxic. It is high in protein (nitrogen) and trace minerals and the goat feces are a good source of fertilizer as well. Water hyacinth is reported for its efficiency to remove about 60–80% nitrogen [123] and about 69% of potassium from ...
