Resumen
Se experimentó la producci6n de lombriabono con Bisenia fetida y Glososcolex sp. en condiciones de campo, invernadero y laboratorio. Las lombrices fueron alimentadas con estiércol de bovino, cereza de café y basuras biodegradables solos y combinados. Los resultados mostraron que las dietas en las que se incluyó cereza de cafá producen los mejores efectos en cuanto a obtención de biomasa animal y en las propiedades fisicoquímicas del suelo como la CCC, contenido de bases totales, materia orgánica, nitrógeno total, fósforo y microelementos. La actividad de Glossoscolex sp., sobre las propiedades anteriores es ligeramente inferior a la manifestada por E. fetida, cuya producción puede masificarse bajoo condiciones ambientales semicontroladas. El uso del lombriabono reporta ahorros cercanos al 50%, con respecto a la fertilización tradicional.
An experiment was carried out to try the manure production by earthworm activity in field, greenhouse and laboratory conditions. E. fetida and Glossoscolex sp. were fed by a basic ofbovine manure, coffe pulp and biodegradable farm wastes, all ofthem combinated with each other or alone. the result show that the best effecta about animal biomass production and certain soil conditions, like cation exchange capacity, base saturation, organic matter, total nitrogen and phosphorus and soíl micronutrients are obtained when coffee pulp was used. Glossoscoles sp. activity resulted to be slowly less than that of E. fetida, the production ofwhich could be massively obtained under semicontrolled enviroment conditions. The use of earthworm manure makes savings about 50% as compared to traditional fertilization.
