Subtropical China is the focus of this dataset, which contains 2,357 paired observations from a global meta-analysis of soil nitrogen transformation changes due to agricultural intensification. It includes topsoil samples from 54 paired agroecosystem and forest sites, analyzed via nifH amplicon sequencing, shotgun metagenomics, and cultivation assays. The dataset, authored by Fu Ruoxian and last updated in May 2026, also provides 152 high-quality nitrogen fixation-associated metagenome-assembled genomes (nfMAGs).
Use Cases
- Modeling changes in soil nitrogen functions based on paired observations of agricultural and forest sites.
- Analyzing microbial functional potential based on 152 recovered nitrogen fixation-associated metagenome-assembled genomes.
- Comparing soil microbial communities between agroecosystems and forests using nifH amplicon sequencing data.
- Studying the effects of agricultural intensification on a global scale using the meta-dataset of 2,357 observations.
Strengths
- Includes a substantial global meta-dataset of 2,357 paired observations.
- Provides detailed field survey data from 54 paired sites across six regions.
- Contains genome-resolved analyses with 152 high-quality nitrogen fixation-associated metagenome-assembled genomes.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count for the primary data tables is unknown, which may limit suitability assessment.
- Geographic coverage is focused on subtropical China, which may limit generalizability.
