Distribution of Microorganisms and Fractionation of Sulphur in Anthropogenic Wetlands under Long-term Elevated CO2 Soil

The fate of extra carbon accessing soil under elevated CO2 levels, as well as the repercussions for plant nutrition, is primarily determined by soil microbe activity. However, most increased CO2 research has reported changes usually increases in soil organic carbon and reduction in the pH of the soil which is merely the first step in understanding how soil processes are altered. We analyzed these variables by assessing enzyme activities and identifying the individual components impacted by high CO2 and those that reflect changes in soil organic matter pools. The majority of the microbial variables studied showed a significant increase under eCO2 conditions, The rise in dehydrogenase activity suggests that the increased biomass of bacteria coincided with an increase in their activity. The rise in phosphatase activities implies that organic matter breakdown is being stimulated overall. The sulphur fractions had a significantly increased number of substrates consumed by soil microorganisms under increasing CO2. Moreover, direct examination of data from these perspective steep shifts in soil biological activity points to possible areas of investigation.
