Résumé : |
The purpose of this work is to assess the risks deriving from current forestry practices on the sustainability of soil function and ecosystems. The relationship between the production function and the soil conservation function translates as a certain conflict between these two options. Stresses on the chemical fertility of the soil were analysed from the least intensive to the most intensive treatments, i.e. from forest reserves to very short rotation, treated lignocellulosic crops. Under the extensive systems, high grade biological recycling is sustainable if logging is confined to trunks alone. Dressings can correct the slow but inevitable acidification of soils. When treatments are intensive, the natural fertility of forest soils cannot sustain production; only soils with suitable[...]
The purpose of this work is to assess the risks deriving from current forestry practices on the sustainability of soil function and ecosystems. The relationship between the production function and the soil conservation function translates as a certain conflict between these two options. Stresses on the chemical fertility of the soil were analysed from the least intensive to the most intensive treatments, i.e. from forest reserves to very short rotation, treated lignocellulosic crops. Under the extensive systems, high grade biological recycling is sustainable if logging is confined to trunks alone. Dressings can correct the slow but inevitable acidification of soils. When treatments are intensive, the natural fertility of forest soils cannot sustain production; only soils with suitable physical qualities combined with application of appropriate inputs enable sustained high levels of output to be achieved, in particular under the short rotation systems.
