The effects of pH on nutrient availability are not solely caused by to the effects on reaction
with soils but are an interaction between these effects and the effects on rate of uptake by …

At the global scale, among all N (nitrogen) species in the atmosphere and their deposition
on to terrestrial vegetation and other receptors, NH3 (ammonia) is considered to be the …

Nitrogen (N) is the most important, essential nutrient for all living organisms on earth; it is
present in a number of complex organic molecules and plays extremely important roles in …

THE high incidence of failure when late-successional conifer species are replanted on
disturbed forest sites is a considerable problem1–3. Here we advance a hypothesis that …

THE importance of nitrate (NO–3) in the internal nitrogen cycle of undisturbed coniferous
ecosystems has not been widely recognized1, 2. Nitrate concentrations in soils from these …

Atmospheric ammonia does not only cause acute injuries at vegetation close to the source,
but significantly contributes to large scale nitrogen eutrophication and acidification of …

This manual offers foresters information to help them understand the performance of spruce
seedlings after being planted on a reforestation site. It was written for university students …

Short-term influxes of 13NH4+ were measured in intact roots of 3-week-old rice (Oryza
sativa L. cv M202) seedlings that were hydroponically grown at 2, 100, or 1000 [mu] M …

Abstract Background and Aims Tea (Camellia sinensis) is considered to be acid tolerant and
prefers ammonium nutrition, but the interaction between root zone acidity and N form is not …

Abstract The NH4+ and NO3–uptake kinetics by Typha latifolia L. were studied after
prolonged hydroponics growth at constant pH 3.5, 5.0, 6.5 or 7.0 and with NH4+ or NO3–as …
