| Popis: | Due to a need for sustainability in agriculture, waste products ought to be utilized in the most appropriate way. A study was undertaken relating to the vermicomposting of Cameroon sheep dung (CSD) by the earthworm Dendrobaena veneta. Processing of this waste was investigated using unadulterated CSD and in a 1:1 mixture with unpalatable (waste) hay (CSDH). Results demonstrated that these materials were actively processed by D. veneta with vermicomposts obtained which can be characterized by a higher amount of total nitrogen, phosphorus and potassium (average, respectively, 17.0, 10.5, 13.2 g kg&minus 1 d.m.), as well as lower total carbon and magnesium content (respectively, 340 and 3.2 g kg&minus 1 d.m.), compared with the initial waste material. No significant differences were found between CSD and CSDH vermicomposts with respect to chemistry. Levels of selected trace elements (average: Cu 17.5&ndash 18.8, Cr 5.7&ndash 5.8, Pb 13.5&ndash 14.4, Ni < 3, Cd < 0.4 mg kg&minus 1 d.m.) in both vermicomposts did not exclude their application to agricultural soil as a fertilizer. |
