Nitrogen-cycle Genes and Transcripts Abundances under Agricultural Management Practices in a Long-term Continuous Cotton Field

Soil microbial transformations of nitrogen (N) can be affected by soil health management practices. Here, we report in situ seasonal dynamics of the abundance (gene copies) and expression (transcript copies) of five bacterial genes involved in soil N cycling (AOB amoA, nifH, nirK, nirS, and nosZ) in a long-term continuous cotton production system under different management practices (cover crops, tillage, and inorganic N fertilization). In addition, the abundances of 16S rRNA gene and 16S rRNA were also measured to normalize the abundances of these five N-cycle functional genes and transcripts.
