Combining δ13C measurements and ERT imaging: improving our understanding of competition at the crop-soil-hedge interface

Hedgerow cropping decreases erosion in hillside agriculture but also competes for water and nutrients with crops. This study combined two methods for an improved understanding of water and nutrient competition at the crop-soil-hedge interface. δ13C isotopic discrimination in plants and soil electrical resistivity tomography (ERT) imaging were used in a… (More)
