Trifolium repens L. was grown to test the following hypotheses: when P is deficient (i) N 2 fixation decreases as a result of the plant's adaptation to the low N demand, regulated by an N feedback mechanism, and (ii) the decrease in the photosyntheti

Human activities are responsible for the strong and very fast increase in the concentration of atmospheric CO2 over the past 100 years; this trend will continue. An increase in CO2 is expected to affect significantly grassland vegetation, which cover

Effects of free-air carbon dioxide enrichment (FACE, 60 Pa pCO2) on plant growth as compared with ambient pCO2 (36 Pa) were studied in swards of Lolium perenne L. (perennial ryegrass) at two levels of N fertilization (14 and 56 g m−2 a−1) from 19

Rising atmospheric carbon dioxide partial pressure (pCO2) and nitrogen (N) deposition are important components of global environmental change. In the Swiss free air carbon dioxide enrichment (FACE) experiment, the effect of altered atmospheric pCO2 (

Plant response to increasing atmospheric CO 2 partial pressure ( p CO 2 ) depends on several factors, one of which is mineral nitrogen availability facilitated by the mineralisation of organic N. Gross rates of N mineralisation were examined in grass

Emissions of N2O were measured during the growth season over a year from grass swards under ambient (360 μL L−1) and elevated (600 μL L−1) CO2 partial pressures at the Free Air Carbon dioxide Enrichment (FACE) experiment, Eschikon, Switzerland.

Emissions of N2O and N2 were measured from Lolium perenne L. swards under ambient (36 Pa) and elevated (60 Pa) atmospheric CO2 at the Swiss free air carbon dioxide enrichment experiment following application of 11.2 g N m−2 as 15NH415NO3 or 14NH415

The influence of N availability on C sequestration under prolonged elevated CO2 in terrestrial ecosystems remains unclear. We studied the relationships between C and N dynamics in a pasture seeded to Lolium perenne after 8 years of elevated atmospher
