发明名称 Growing medium containing combusted bark particles
摘要 A growing medium for seeds, cuttings, plants and the like contains partially combusted bark particles obtained from bark-burning boiler furnaces of pulp processing concerns. The bark particles possess physical and chemical properties ideally suited for use in growing media, especially so-called "soilless" growing media for container-growing. The combusted bark particles are combined with other materials conventionally utilized in horticultural growing media.
