An indicator of the water use of C3 plants is their natural abundance of the carbon isotope 13C. Without water stress, plants may fractionate more against 13C than with water stress, leading to a stronger depletion of 13C in plant material. We have used this principle to investigate the water use of grassland differing in diversity. In old grassland, diversity was altered three years before this experiment by applying a herbicide against dicots in half of the plots. On sub-plots, different combinations of rainout shelters (yes-no) and N fertilisation (0 or 90 kg ha-1) were established. Differences between drought treatments were clearly reflected in 13C values. N fertilisation led to a further enrichment in 13C, especially in unsheltered conditions. This could be explained by increased biomass production, which might have led to higher water use, and enhanced CO2 fixation capacity. Unexpectedly, plant diversity did not have a significant influence on the isotopic composition. This was perhaps due to the occurrence of the deep-rooted Taraxacum sp. on all plots and the similar species numbers in herbicide-treated and -untreated plots."],["dc.identifier.gro","3147925"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5258"],["dc.language.iso","en"],["dc.notes.status","fcwi"],["dc.notes.submitter","chake"],["dc.publisher","EGF"],["dc.relation.conference","23rd General Meeting of the European Grassland Federation"],["dc.relation.crisseries","Grassland Science in Europe"],["dc.relation.eventend","2010-09-02"],["dc.relation.eventlocation","Kiel, Germany"],["dc.relation.eventstart","2010-08-29"],["dc.relation.isbn","978-3-86944-021-7"],["dc.relation.ispartof","Grassland in a changing world.
