Belowground Crop Ecology

Our research group focuses on belowground interactions between roots and their surrounding environment, contributing to the development of resilient cropping systems with efficient resource use.

Root system development and function play an important role in future more sustainable cropping systems. We investigate the development, uptake, and plasticity of roots and the responses to the soil conditions and abiotic stresses. We have a strong focus on yield stability of legumes for food and feed with emphasis on root development, drought tolerance as well as root interactions in intercropping systems. Furthermore, we study roots, acquisition of water, phosphorus, and nitrogen and root interactions at different scales from field to lab.

 

 

 

Root development and drought tolerance: we investigate the effect of rooting depth and distribution on tolerance towards environmental stressors such as drought.

Protein crops: we aim to develop more sustainable cropping systems including legumes with improved yield stability as a protein source for food and feed. We provide novel knowledge on the root systems of forage and grain legumes and the significance for more climate-smart systems.

Plant based food: We work with old cultivars of pea to find well-tasting, high quality protein sources that are agronomical realistic to grow for plant based foods

Intercropping: we aim to unravel root competition, facilitation and complementarity when growing two or more species together.

Root system development in 3D:  we are applying CT scanning to root systems in soil uncovering the three dimensional root development over time.
