Key disease‑resistant biological clusters of black soil

Core soil microbiome datasets for the Mollisol zone of Northeast China. This dataset focuses on the effects of land‑use change (grassland to farmland) and temperature gradients on soil microbial communities, and is integrated with soil nematode diversity research.

It provides fundamental data support for the functional maintenance and sustainable utilization of black‑soil ecosystems. 2. Core functional‑gene datasets for investigating land‑use change (grassland to farmland) in the Northeast China Mollisol zone. It focuses on microbially‑mediated soil biogeochemical cycles (carbon, nitrogen, phosphorus and sulfur cycles) and metabolic pathways.
