soil metagenome-ITS
Grazing removal is a main method for restoring degraded soda-saline grasslands in Songnen Plain. This study found that Leymus chinensis is recommended for restoration and carbon sequestration, and that vegetation restoration improves soil properties and microbial communities. Salinity was highest in bare land and lowest in reed vegetation, and soil organic matter content and SOC were higher in vegetated soils. Bacterial and fungal communities varied between restoration types, with pH being the main cause of microbial differences. The difference in soil organic matter was mainly due to pH, and reducing soil pH is a key step for future restoration efforts.
