In eight field experiments dried municipal sewage sludge was applied to forest sites before planting of seedlings. In all cases, tree growth was faster on sludge-amended plots than on plots that received fertilizer and lime or no amendment. In all studies, concentrations of total nitrogen in the soil were higher on sludge plots than on control or fertilizer plots, even on good forest sites. In seven of the eight studies, concentrations of phosphorus also were higher on sludge plots than on control or fertilizer plots. Nitrogen and phosphorus tended to be higher in foliage from trees growing on sludge plots. Deep subsoiling was beneficial regardless of soil amendment. Where weeds were plentiful at the outset, they became serious competitors on plots receiving sludge.

The treatment and disposal of sewage sludge is an expensive and environmentally sensitive problem that is growing worldwide. Sludge production is increasing whilst previously accepted methods for disposal are coming under pressure or even being phased out altogether so there is now an urgency to find cost-effective and innovative solutions that appease environmental and public pressures. The purpose of the conference recorded in these proceedings was to review the range of alternative disposal/recycling options for sewage sludge. The alternative uses considered are in land reclamation, forestry, compost and soil production, landfill, incineration, and energy and resource recovery. The papers presented include recent research findings and technological developments, as well as operational implementation of schemes, showing that beneficial re-use of sludge can be entirely compatible with a cost-effective and environmentally sensitive approach to sludge disposal.

Forest soil characteristics are not only unique but their interpretation also differs from cropland soils. Just as there are diverse forest types, there are many soil variants that need different management. Today, forest plantations are being intensively managed for profitable timber, pulpwood and energy production. Site selection, species selection, site productivity evaluation, silvicultural treatments, and soil amendments need crucial soil information. This book provides a comprehensive overview of the physical, chemical and biological properties of forest soils and their implications on forest vegetation. Topics discussed include: major forest types of the world and their associated soils; forest biomass and nutrient dynamics; organic matter turnover and nutrient recycling; forest soil disturbance; forest soil and climate change; and forest soil management and silvicultural treatments.
