Fig. 7From: Elevated atmospheric CO2 impact on carbon and nitrogen transformations and microbial community in replicated wetlandAverage total N content was lost by CO2 enrichment between two treatments from beginning to end of the experiment. The average percent showed different TN content between the two chambers. The length of each value was mean indicated in elevated CO2 (black) and ambient CO2 (white) and standard error (S.E.) located on the length of valuesBack to article page
