Research on plant nitrogen (N) uptake and metabolism has more or less exclusively
concerned inorganic N, particularly nitrate. Nevertheless, recent as well as older studies …

A wide range of recent studies have indicated that organic nitrogen may be of great
importance to plant nitrogen (N) nutrition. Most of these studies have, however, been …

Languishing for many years in the shadow of plant inorganic nitrogen (N) nutrition research,
studies of organic N uptake have attracted increased attention during the last decade. The …

In this study, we assessed whether a range of temperate grassland species showed
preferential uptake for different chemical forms of N, including inorganic N and a range of …

Demand of all living organisms on the same nutrients forms the basis for interspecific
competition between plants and microorganisms in soils. This competition is especially …

Nitrogen (N) availability has a major impact on a wide range of biogeochemical processes in
terrestrial ecosystems. Changes in N availability modify the capacity of plants to sequester …

As an estimate of species-level differences in the capacity to take up different forms of N, we
measured plant uptake of 15 N-NH 4+, 15 N-NO 3− and 15 N,[1]-13 C glycine within a set of …

Background and aims Plants differ in their ability to use different nitrogen (N) chemical forms,
these differences can be related to their ecology and drive community structure. The …

Uptake of glycine was studied in four plants commonly used in grasslands in northern
Europe (Phleum pratense, Trifolium hybridum, T. pratense, and Ranunculus acris) and …

The traditional view of the nitrogen (N) cycle has been challenged since the discovery that
plants can compete with microbes for low molecular weight (LMW) organic N. Despite a …
