dc.description.abstractSeasonal means of light saturated (PAR > 1000 micromol m-2 s-1) ecosystem carbon dioxide fluxes, temperatures and water table and peak season vegetation observations at Mer Bleue Fertilization experiment, Ottawa, Canada. CO2 fluxes were measured with a transparent, climate-controlled chamber and shrouds during May-August in 2001-2011. During the time period, most of the collars in Experiment 1 (control O and treatments PK, 5N, 5NPK started in 2000; 10NPK, 20NPK in 2001) were measured in 2001, 2003, 2005, 2008, 2009, 2011 and most collars in Experiment 2 (Control X and treatments 10N, 20N started in 2005) in 2008, 2009, 2011. Seasonal means were based on approximately 10 flux measurements from May-August (see MBfert_NetCO2Exchange_instantflux_2001-2011.xls). Vegetation measurements include the height of the shrub canopy, and Sphagnum and Polytrichum moss cover recorded in July 2000-2013. During the time period, the collars in Experiment 1 (control O and treatments PK, 5N, 5NPK 10NPK, 20NPK) were measured in 2001, 2003, 2005, 2007, 2008, 2009, 2011, 2012, 2013 and the collars in Experiment 2 (Control X and treatments 10N, 20N) in 2005 (moss cover only), 2007, 2008, 2009, 2011, 2012, 2013. Also included are estimates for plant area indices (LAI) 2008, 2009, 2011 (See methods).
dc.description.abstractAnnual N application levels as NH4NO3 since the beginning of the respective treatments: 5 (1.6 g N m-2), 10 (3.2 g N m-2) and 20 times (6.4 g N m-2) ambient summer time wet N deposition (0.8 g m-2y-1 in 2000) with or without P (5.0 g m-2) and K (6.3 g m-2) as KH2PO4. Distilled water served as control. Nutrient solutions were applied every 3 weeks May-August on triplicate 3 x 3 m plots. For details of the experiment and data see the following publications:
