TL;DR: In this article, the authors review responses to simulated N deposition from nine experimental sites across the UK in a diversity of heathland, grassland, bog and dune ecosystems which include studies with a high level of realism and where many are also the longest running globally on their ecosystem type.

TL;DR: Analysis of the course of events in leaf four following salinization of the medium showed that net photosynthesis was inversely correlated with the sodium concentration in the leaf tissue, and the relationship between transpiration rate and leaf sodium concentration closely paralleled that for photosynthesis.

TL;DR: Regular applications of ammonium nitrate and ammonium sulphate to areas of acidic and calcareous grassland in the Derbyshire Peak District over a period of 6 years have resulted in significant losses in both overall plant cover and the abundance of individual species, associated with clear and dose-related increases in shoot nitrogen content.

TL;DR: In this article, a review of previous experimental findings and new experimental evidence from an acidic and a calcareous grassland, both showing phosphorus limitation, and a N-limited Calluna vulgaris (L.) Hull heathland in upland Britain is presented.

TL;DR: In this article, an index of "ANC forcing" of the effect of fertilization on the acid-base balance was calculated, which showed that dissolved organic carbon (DOC) concentrations increased in response to all deacidifying N additions, and decreased in response for all but three acidifying N addition.
