The Potential for Using Sewage Sludge in Forestry in England and Wales
Forestry Commission Research Station, Alice Holt Lodge Wrecclesham, Farnham, Surrey, GU10 4LH
The potential for using sewage sludge as a forest fertilizer on nutrient-deficient sites in England and Wales is evaluated as the first part of a study covering the whole of Great Britain. Suitable areas within Forestry Commission forests are assessed using the Forestry Commission subcompartment database, and Census data in respect of private woodlands. Most Forest Districts contain forests which are likely to benefit from sewage sludge application, mainly in the form of liquid sludge to thinned stands, but also before and just after planting. The environmental effects of sludge application are discussed, and it is concluded that at rates appropriate to forest fertilizing, there is little risk of toxicity or pollution.
