NOVELTY - Preparing biohumus involves stacking organic substrate for layers formed by longitudinal distribution of fresh feeding consisting of non-pressed organic substrate followed by placing worm population on the substrate. After formation of substrate layers fresh feeding is applied surface so that compost worms migrate continuously and form active zone of vermicomposting and vermiculturing.    USE - For preparing biohumus.    ADVANTAGE - Method provides reducing cost in producing biohumus due to simplifying a method for its preparing and enhancing output. Invention can be used in utilization of waste in animal husbandry, residues of wastes and organic waste using rain worms and for preparing valuable organic fertilizer.    DETAILED DESCRIPTION - Preparing biohumus involves stacking organic substrate for layers formed by longitudinal distribution of fresh feeding consisting of non-pressed organic substrate followed by placing worm population to the substrate. After formation of substrate layers fresh feeding is applied on similar right or left lateral sides of all layers by all surface of each lateral side by a layer wherein compost worms migrate continuously and form active zone of vermicomposting and vermiculturing. Then after formation of biohumus the following feeding layer is applied on a layer wherein compost worms migrate continuously also and form the next active zone of vermicomposting and vermiculturing and a layer of ready biohumus is removed from the opposite left or right lateral side of each layer, respectively. Applying layers of feeding and gathering ready biohumus is carried out up to the complete using the parent distance between adjacent layers that provides the gradual transferring active zones of vermicomposting and vermiculturing and, therefore, all layers to a single site for the distance value between adjacent layers. Then feeding is applied on opposite initially taken lateral sides of all layers, and the process is repeated again providing the graduate transferring active zones of vermicomposting and vermiculturing and, therefore, all layers to another site and returning all layer to the initial point, and then all process is repeated.
