Research was undertaken to determine the beneficial and harmful effects of using dewatered, digested sewage sludge in: (1) containerized production of forest tree seedlings, (2) tree seedling production in a conventional outdoor nursery, (3) establishment and growth of transplanted bare-root coniferous seedlings grown in the field as Christmas trees, and (4) formation and survival of mycorrhizae on forest trees and soybeans. Toxicities of various elements were determined, as were sludge-induced nutrient deficiencies associated with various sludge types and application rates.
