Title: Reclamation of borrow pits and denuded lands: Final report, September 1, 1976 to December 31, 1985

Technical Report ·
OSTI ID:6479221

Since 1976, the five scientists in the Institute for Mycorrhizal Research and Development (IMRD) have outplanted and maintained over 80,000 experimental tree seedlings in 27 different field experiments. Information resulting from this research has immediate value in the management of forest stands and soils at the Savannah River Forest Station. Important points include dried municipal sewage sludge at a broadcast rate of 1/2 to 1 inch disked into subsoiled borrow pits will support growth of loblolly pine (container- and bare-root nursery-grown), sweetgum, yellow poplar, green ash, sycamore, sawtooth oak, and black walnut that is 3 to 5 times greater after 4 to 12 years than fertilizer plus lime treatments; sweetgum, an economically important eastern hardwood, can be artificially regenerated successfully by selection of proper seed source and by manipulation of certain nursery procedures, such as available phosphorus levels and vesicular-arbuscular mycorrhizal colonization of feeder roots needed to produce quality seedlings; the number of first order lateral roots on sweetgum, oak, walnut, loblolly pine, and longleaf pine appear to be under strong genetic control; and the quality and quantity of ectomycorrhizae on container-grown or bare-root seedlings of loblolly and longleaf pines have a highly significant effect on their field performance. 17 refs.
