Abstract
Mycorrhizae, or “fungus-roots” involve the intimate association of plant roots with specialized soil fungi. Foresttree seedlings depend upon their mycorrhizae for adequate nutrient uptake; those lacking mycorrhizae can be severely stunted and their growth in newly sown beds uneven. Nursery managers should avoid practices that cause mycorrhiza deficiency. For example, because soil fumigation destroys mycorrhizal fungus populations, alternative pest-control measures should be substituted whenever possible. Careful seedling manipulations and handling also will reduce damage to mycorrhizae. Soil disturbance should only be necessary to meet management goals so as to minimize disruption of delicate fungussoil networks. Fertilization can both foster and inhibit mycorrhiza development; appropriate levels are best determined by experience. The integrated use of mycorrhizamanagement tools with other cultural practices and the potential use of selected beneficial fungi for mycorrhizal inoculation of seedlings will help ensure the successful production of vigorous planting stock.
