Abstract

Utilizing sludge, sediment from treated town sewage, as forest fertilizer, rather than discharging it into waterways, could turn a liability into an asset; and play an important role in Canada's environmental conservation program. Sewage sludge was used as a fertilizer in a plantation at Grand'Mère, Quebec, and proved a valuable growth stimulator. The addition of 500 lb/acre of dry sludge to a low quality sandy soil in this area increased height growth of a 10-year-old white spruce plantation considerably by 13% after 2 years, 20% after 3 years, and 30% after 4 years.
