This study is to examine soil microbial community composition and structure of both bacteria and fungi at a microbially-relevant scale. The researchers isolated soil aggregates from three land management systems in central Iowa to test if the aggregate-level microbial responses are related to plant community and management practices. The clean dataset has 120 samples with 17 genus under consideration.
