In-situ vermicomposting and biochar synergistically alleviate salt stress and reshape nitrogen-cycling microbiomes in brackish-water-irrigated soils
Soil samples were collected from solar greenhouse cultivated with cucumber under micro saline water drip irrigation. Treatments included biochar and earthworm manure amendments. Whole genome shotgun metagenomic sequencing was performed to investigate the effects of soil amendments on soil microbial community and nitrogen cycling functional genes.
