Abstract
Three sludges - aerobic, anaerobic, Milorganite, and peat moss were tested for fertilizing ability, seed inhibition, and chemical composition. Using green bean (Phaseolus sp.) and rye grass (Lolium perenne) seeds in two sludge amended soils, a greenhouse study indicated growth enhancement for the rye grass and variable results for the green beans. Algal and fungal contaminations were problems. Seeds germinated in sludge extract were inhibited, but no correlation with the chemical analyses could be established. Only Milorganite had a heavy metal content significantly higher than the soils tested.
