A group from Key Laboratory of Mollisols Agroecology, Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences, Harbin, China, etch. has reported about changes in dominant bacterial and fungal taxa due to chitin addition into soybean soils.
Chitin addition is considered promising methods for alleviating soybean continuous cropping obstacles, however, the underlying mechanisms of soil sickness reduction remain unclear.
In this study, changes in dominant bacterial and fungal taxa due to chitin addition were evaluated.
At the bacterial OTU level, chitin distinctly increased the relative abundance of Streptomyces, Sphingomonas, Bacillus, Mesorhizobium and Nitrospira. At the fungal phylum level, chitin addition markedly increased the relative abundance of Zygomycota, and conversely drastically reduced the relative abundance of potential pathogens affiliated with Fusarium, Paraphoma, Cylindrocarpon and Septoria.
