- Evaluated stratified and balanced sampling approaches against random sampling for efficiently estimating soil organic carbon (SOC) in agricultural soils.
- Double balanced sampling showed great promise in reducing the number of samples needed to estimate SOC when coupled with remote sensing data, SSURGO estimates, and topography.

- Studied the ecosystem services (ES) from shrub willow buffers in a row crop system.
- Soil health and crop productivity of willow and grain crops were evaluated.
- Landscape position and crop type influenced the soil microbial community present.
- Microbial taxa were highly correlated with soil chemical parameters, especially pH.
- Landscape position influenced the ES provision by willow buffers.
