Composting and Vermicomposting Techniques

This research aims to value the chemical composition, the food preference and the earthworms Eisenia andrei (Bouché, 1972) multiplication, from animals residues. The used residues were bovine rumen content, rabbits manure, ovine manure and bovine manure. The evaluation of vermicomposting process consisted of four treatments with six repetitions. PVC black pots containing 2 kg of the dry matter residues were used for each one of the repetitions, in which 90 clitellates earthworms were inoculated. It was evaluated the residues chemical composition at the time of the experiment installation, and after 90 days of vermicomposting were carried out the earthworms reproduction. The evaluation of food preference consisted four repetitions for each studied residues. PVC role pots with each treatment residues inside, were introduced in a composted with earthworms. The food preference was valued by the residues after 14 days. The food preference and the earthworms' reproduction are favored by the bovine manure and by the rumen bovine content. The rabbit manure has higher levels of chemical nutrients and heavy metals then the bovine manure, ovine manure and rumen bovine content.
