Title: Feasibility of growing hardwood species on a borrow pit amended with either fertilizer and lime or sewage sludge. Progress report

Previous research on other sites showed that 15 tons/A of dried sewage sludge followed by subsoiling is sufficient to promote rapid growth of pines and sweetgum on borrow pits. During the past year, data have been obtained from this experiment showing that 30 tons/A of sewage sludge, well incorporated and followed by subsoiling, will promote very rapid first-year growth of green ash, yellow poplar, sycamore, and sawtooth oak. Loblolly pine and sweetgum also grew well as in previous studies. In most cases, seedlings of these species grew significantly faster with sewage sludge than with 1000 lbs./Aof 10-10-10 fertilizer and 2 tons/A of lime. Yellow poplar and sycamore grew the faster of all species, attaining heights during the first growing season of 134 and 209 cms, respectively. Sweetgum, green ash, and sawtooth oak all attained heights over 100 cms.
