Shovelomics: Measuring faba bean root traits in the field
Problem:
Root systems are essential for faba bean productivity because they determine how effectively plants acquire water and nutrients and interact with soil organisms. However, studying and measuring roots in the field is far more labour-intensive and complex than assessing above-ground plant traits.
Solution:
To support efficient and standardised field assessment of faba bean root architecture, the shovelomics method was developed and validated. It provides a practical way to characterise root traits directly from excavated plants using simple tools.
Principle:
Shovelomics involves excavating plants to a depth of about 20 cm, washing the root crown, and evaluating the 3D structure of the root system using a shovelomics board. The method allows measurement of key traits, including root angle, taproot diameter, maximum root depth, root number and length, epicotyl root number, and biomass, with optional assessment of nodulation.
Benefits:
The method is well-suited for high-throughput phenotyping in breeding and research programmes and does not require specialised equipment. It enables consistent measurement of relevant faba bean root traits within the topsoil layer (0–20 cm). Additional parameters, such as root dry weight or nodulation activity, can be included when needed to extend the analysis.
