The Soil Microbiome: Linking Soil Biodiversity to Soil Health and Ecosystem Services
Understanding the microbial world in the soil is key to finding sustainable agricultural practices that work to protect the environment. Using a unique approach that combines the disciplines of soil science and molecular biology, we are able to quantif …

Crop rotations differ in soil carbon stabilization efficiency, but the response to quality of structural plant inputs is ambiguous
This study set out to evaluate crop rotation diversity, perenniality, carbon inputs, and carbon input quality as predictors of soil organic carbon concentration and aggregate size.
Long-term diverse rotation alters nitrogen cycling bacterial groups and nitrous oxide emissions after nitrogen fertilization
This study measured the impact of 35 years of crop rotation diversification on soil microbial communities and nitrous oxide (N2O) emissions.
