The root system architecture and its interactions with soil microorganisms play a key role in crop performance, particularly in the capture of water and mineral elements. Studying roots is more complicated than studying the above-ground parts. To facilitate the complex study of root systems, the shovelomics method was validated. The method measures root traits on plants sampled with a spade. With that simple method, we can access the 3D architecture of the main roots growing into the ridge. This factsheet explains the method for potatoes. For more information, please see the associated video: https://www.youtube.com/watch?v=eVXViOC_-9Q
