Abstract

The concentration of macro and micronutrients in roots, stems and leaves of water hyacinth was determined. One kg of the whole plant contains the following quantities of elements: N-10.3g, P-1.6, K-49.0, Ca-25.8, Mg-10.5 and S-3.3; B-25mg, C@-10,436, Co-1.9, Cu-1.2; Fe-8,969, Mn-1,415, Mo-2.3, Ni-4.0 and Zn-41.6. After comparing the composition of water hyacinth with that of stable manure, its use as green manure is discussed.
