摘要

Pine bark is the most common nursery substrate used for horticulture container crop production in the Southeastern United States. In recent years, pine bark supplies for horticultural production have begun to decline due to reduced domestic forestry production and increased use of pine bark as a fuel. In many areas in the Southeast, pine bark suppliers are unable to fill orders for container nursery producers with limited supplies, leading to possible price increases. So it's important to develop alternative substrates for use in container production of horticultural crops.Container substrates composed primarily of wood and wood-based products have been heavily investigated in recent years. The use of wood fiber substrates has been successful in production of vegetables, annuals and perennials and woody ornamentals. For alternatives to be considered suitable substrate replacements, they must not only have desirable characteristics as a container substrate—adequate drainage, inert, pathogen free, and so on—but must also cause no negative fertility effects (for example, nitrogen immobilization) following planting in the landscape. Before widespread adoption of these materials can take place, landscape performance of plants produced in these substrates must be established.
