Root Growth and Response to Nitrogenperiments, 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 (.; see also .). Some nitrogen fertilisation experiments sugg

Nitrogen Uptake Processes in Roots and Mycorrhizason followed by nitrification and anthropogenic deposition will, in addition, combine and provide the inorganic forms ammonium (NH..) and nitrate (NO..) in amounts and ratios which will depend upon local conditions of soil, climate and pollutant deposition. While Åheden, the most northerly site of th

Canopy Uptake and Utilization of Atmospheric Pollutant Nitrogenacidifying soils (.; .) and because it can be easily monitored. By contrast, the deposition of pollutant gases has not received an equivalent amount of attention, even though the ecological importance of this process has long been recognised (.; .). Understanding of gas interactions with canopies ha

Biotic and Abiotic Controls Over Ecosystem Cycling of Stable Natural Nitrogen, Carbon and Sulphur Istures of N, C and S compounds due to fractionation. Thus, tracing processes of isotopic fractionations in forest ecosystems can help identify transfer pathways and capacities. Atmospheric nitrogen pollution has been recognised as the cause for formerly N-limited forests to approach N saturation (.,

Ecosystem respiration includes autotrophic and heterotrophic processes: the first is caused by the growth and maintenance of plant tissues, while the second is mainly the result of the decomposition of litter and soil organic mat

In materials with a low decomposition rate, determination of CO. evolution rate is a more sensitive way of estimating decomposition during a limited period of time than determining weight loss in litterbags. The efflux of CO. from soil (soil
