AbstractWetland ecosystems are important reservoirs of biodiversity and significantly contribute to emissions of the greenhouse gases CO2, N2O and CH4. High anthropogenic nitrogen (N) inputs from agriculture and fossil fuel combustion have been recognized as a severe threat to biodiversity and ecosystem functioning such as control of greenhouse gas emissions. Therefore it is important to understand how increased N input into pristine wetlands affects the composition and activity of micro-organisms, especially in interaction with dominant wetland plants. In a series of incubations analyzed over 90 days, we disentangle the effects of N fertilization on the microbial community in bulk soil and the rhizosphere ofJuncus acutiflorus, a common and abundant graminoid wetland plant. We observed an increase in greenhouse gas emissions when N is increased in incubations withJ. acutiflorus, changing the system from a greenhouse gas sink to a source. Using 16S rRNA amplicon sequencing and metagenomics, we determined that the bacterial orders Opitutales, Subgroup-6 Acidobacteria and Sphingobacteriales significantly responded to high N availability and we hypothesize that these groups are contributing to the increased greenhouse gas emissions. These results indicated that increased N input leads to shifts in microbial activity within the rhizosphere, severely altering N cycling dynamics. Our study provides a framework for connecting environmental conditions of wetland bulk and rhizosphere soil to the structure and metabolic output of microbial communities.

In this study environmental efficiency of main root crop (sugar beets and potatoes) cultivation in Poland is evaluated. Survey data from 62 sugar beet and 74 potato farms in the years 2016 and 2017 were used for analysis. To assess efficiency, the slack based Data Envelopment Analysis model (SBM-DEA) was used, where greenhouse gas emissions were assumed as undesirable output. The reasons for inefficiency in cultivation were explained using the fractional regression model (FRM), with habitat and organizational conditions as independent variables. Differences in the structure of greenhouse gas emissions from the crops under study were indicated as a result of differences in technology used at each farm. The estimated average carbon footprint on the analysed farms for sugar beet cultivation was 0.057 (±0.042) kg CO2e/kg and 0.13 (±0.17) kg CO2e/kg for potato cultivation. The obtained results indicate that effective farms growing sugar beet emit, on average, 14.5% less greenhouse gases, achieving a slightly higher yield. In potato cultivation, this reduction is 15.3% with a 27% increase in yield. It has been shown that weather conditions and the economic size of farms can significantly affect the environmental efficiency of both analysed crops.
