Abstract
Environmental conditions and nutrient supply do not only affect the above-ground growth of forest trees, but also the below-ground growth. In model experiments, N additions to soil can result in both increases and decreases in root dry weight or root length. More consistently, in most cases a decrease in the root/shoot biomass ratio is observed as a result of increased N supply in soil (George and Seith 1998; see also Chapin III et al. 1987). Some nitrogen fertilisation experiments suggest that much of the increased above-ground production may be due to a carbon translocation from below-ground to above-ground parts (Linder and Axelsson 1982). Although this change in carbon allocation is not necessarily harmful to the tree, on low-nutrient soils a nutrient imbalance may occur in the tree as a consequence of the decreased root/shoot ratio, and this may be one of the factors causing forest decline symptoms. Such effects can also be studied in the field in N-fertilisation experiments (Ahlstrom et al. 1988; Persson et al. 1995a) or N-addition and removal experiments (Clemensson-Lindell and Persson 1995; Persson et al. 1998). In the present experiment, we compared root growth of Norway spruce (Picea abies) and European beech (Fagus sylvatica) at different sites with contrasting climate and N deposition.
