Effect of simulated eutrophication on primary production of a marginal wetland
 TOUPAL, Michal
This Bc. Thesis is part of Project of the Grant Agency of the Czech Republic No. 526/09/1546 entitled ?Importance of newly assimilated carbon for the plant-soil interactions in wet grassland ecosystems in varying environmental conditions?. The aim of the thesis is to estimate the abovground production of a graminoid wetland stand in the Nature reserve Záblatské louky in the Třeboň Basin Protected Landscape and Biosphere Reserve. The work also includes assessment of the effect of several years of fertilization on the plant species composition and the aboveground biomass. The aboveground biomass was sampled at three sampling dates in 2012. A total of 24 samples was taken at each sampling date on plots receiving different levels of fertilizer. The treatments included a high degree of fertilization, an intermediate degree of fertilization and no fertilizer addition. The samples were taken from quadrats of 0,5 x 0,25 m. The biomass values were then expressed per a unit area (1 m2). The highest average values of total aboveground biomass (521,56 g.m-2) were found for non-fertilized plots. Unfertilized plots reached an average value of total aboveground biomass of 480,37 g.m-2. The lowest average value of total aboveground biomass (434,85 g.m-2) was found for the treatment receiving high fertilization. The highest average value of aboveground biomass (652,15 g.m-2) was found for unfertilized plots on the 3rd sampling date. The results showed a statistically significant effect of fertilization on the biomass of Eriophorum angustifolium and mosses.
