Producción de abonos orgánicos con la utilización de elodea (Egeria densa) presente en la laguna de Fúquene
Elodea (Egeria densa), a problem in lakes and lagoons of Colombia, could be a raw material to produce cheap and good quality organic fertilizers. To evaluate the elodea for organic compost production, fertilizers were elaborated with six formulations: 1) Elodea 50%; dolomitic lime 20%; yeast 5%; mel...

| Summary: | Elodea (Egeria densa), a problem in lakes and lagoons of Colombia, could be a raw material to produce cheap and good quality organic fertilizers. To evaluate the elodea for organic compost production, fertilizers were elaborated with six formulations: 1) Elodea 50%; dolomitic lime 20%; yeast 5%; melasse 5%; hene manure 20%. 2) Elodea 60%; dolomitic lime 10%; yeast 3%; melasse 8%; hene manure 19%. 3) Elodea 70%; dolomitic lime 15%; yeast 2%; melasse 3%; hene manure 10%. 4) Formulation 1 + earthworm fertilizer. 5) Formulation 2 + earthworm fertilizer. Formulation y 6) Formulation 3 + earthworm fertilizer. For each fertilizer the total content of N, P2O5, K2O, MgO, CaO, total oxidised carbon, coliforms and C:N were analyzed. Under greenhouse conditions the effect of the fertilizers were evaluated in an Andisol and with lettuce as indicator. During production of the fertilizer temperature and pH were observed. The results showed significant effect of the elements among organic fertilizer. The composition of these fertilizers was according to the requisites for Colombian Organic Fertilizers. The greenhouse experiment showed significant effect of sources and levels on yield and N-P-K content of the lettuce. In general, the formulation three was the best. The pH of the fertilizers varied from 7.0 to7.3, considered adequate. The feasibility to produce good quality organic fertilizers from elodea was demonstrated. |
