FIELD VERMICULTIVATION METHOD Russian patent published in 1997 - IPC

FIELD: agricultural . SUBSTANCE: method involves organic waste composting and preparation of the substrate by mixing composted waste with cellulose-containing and mineral additives. Earthworms are introduced and cultivated in the substrate. In autumn a vermibed is laid for winter vermicultivation near a perforated tube for aeration. A substrate clamp is formed on the tube side, and in early winter the clamp is covered with straw. In a different part of the field peat and manure belts are formed as the weather becomes frosty. The belts are not than 2 m in width and 0.35 v in height. In spring the components of the belts are mixed together and the mixture is moved to lie on warmer soil, and a cone-shaped bed for summer vermicultivation is formed. Compost from the winter vermibed is placed on this bed so that an M-shaped depression is formed. A maternal culture of "manure" and "soil" worms is introduced in the summer vermicultivation bed, and in winter mostly "manure" worms are lured out of the bed. The remainder of compost with young worms and pupas of "soil" worms is distributed over the mulched field surface. EFFECT: continuous year-round process. 2 cl, 3 dwg
