Mycorrhizae and Realistic Nursery Management

In the Pacific Northwest, when producing target seedlings for reforestation of sites that have not been drastically dis- turbed, there will likely be adequate mycorrhiza develop- ment on the seedlings without the necessity of soil inoculation in the nursery. This represents the majority of seedlings being produced. However, problems in the nursery can occur through excessive use of certain pesti- cides, especially soil fumigants and fungicides. These may require re-establishment of mycorrhizal fungi in the nurs - ery soil. When growing seedlings for planting on drastic- cally disturbed or inhospitable sites, or for planting on natural grasslands, nursery inoculation may represent the difference between success or failure. For the future, there exists ample opportunity to significantly increase forest productivity through matching tree genotypes with mycor- rhizal fungus genotypes. At present, however, our knowl- edge base is inadequate for taking full advantage of these possibilities.
