Summary

Fertilisation with N alters the numbers, biomass and seasonal pattern of activity of fine roots and mycorrhizas in spruce humus. Production and mortality decrease, and longevity increases. Fertilisation reduces mycorrhizal infection, alters the relative proportions of mycorrhizal types and permits the appearance of new types.
