Nitrogen addition and removal at Gårdsjön — effects on fine-root growth and fine-root chemistry
Forest Ecology and Management, 1998Investigations were carried out on Norway spruce (Picea abies) fine-root growth in 3 catchment areas subjected to decreased nitrogen (N) and sulphur (S) deposition (G1 ROOF), increased N deposition (G2 NITREX) and ambient levels of N and S deposition (F1 CONTROL), within the Lake Gardsjon basin, SW Sweden.

Plants rely on roots for absorption of nutrients from the soil. Differences in traits of fine roots and of the root system in general thus underlie differences among individual species in their ability to live in habitats differing in nutrient status and interactions with other species.

The root system represents the connecting link between the soil and the above-ground part of the plant. The roots of forest trees have to fulfil different functions. They anchor the trees in the mineral soil and take up water and nutrients from the soil. Making the soil accessible, they change its physical and chemical properties.

Fine Roots and Soil Properties
2000The roots of forest trees consist of long-lived, woody coarse roots and non-woody, small-diameter fine roots. There is no established convention defining the diameter-size range of fine roots (Fogel 1983). In general, however, roots with a diameter of less than 2 mm are regarded as fine roots (Vogt et al. 1983).

Thinning-induced decrease in fine root biomass, but not other fine root traits in global forests
Journal of Environmental ManagementIn forest ecosystems, changes in the expression of tree absorptive root traits following management interventions are expected to influence post-thinning forest structure and function. Fine root traits are expected to be especially responsive to forest thinning-one of the most common forest management interventions and the focus of our research here ...

Fine Root Production and Demography
1999Abstract Attributes of root systems appear to have resulted from pressures on plants to maximize the efficiency of soil resource acquisition and to cminimize the risk of injury or death at environmental or competitive extremes (Yanai et al. 1994).

Long-term changes in soil-water regimes resulting from climate change could have profound effects, not only on aboveground ecosystem processes and productivity but also on belowground processes. Such belowground effects would have corresponding impacts upon nutrient and carbon cycling in forest ecosystems (McClaugherty et al.

Fine-tuning of Bioactive Glass for Root Canal Disinfection
Journal of Dental Research, 2009An ideal preparation of 45S5 bioactive glass suspensions/slurries for root canal disinfection should combine high pH induction with capacity for continuing release of alkaline species. The hypothesis of this study was that more material per volume of bioactive glass slurry is obtained with a micrometric material (< 5 μm particle size) or a ...

The fine structure of the odontoblast/predentin area in the root
European Journal of Oral Sciences, 1971abstract – The fine structure of the odontoblast/predentin area in the apical region of human teeth has been studied. The odontoblasts were characterized by a rich rough‐surfaced endoplasmic reticulum and numerous dense bodies. Between the odontoblasts small bundles of collagen fibers believed to represent the so‐called von Korff's fibers could be ...
