Objectives - Exploiting subsoil resources

The overall aim of the Deep Frontier project is to increase the exploitation of subsoil resources by deep roots in order to enhance food production in a sustainable way. The results will also contribute to climate change mitigation and improved soil biodiversity through the increased organic matter input to the soil, especially in deep soil layers.

The specific objectives of the project are to:

  • Increase our understanding of how deep rooting can be achieved and to identify deep rooted species and cropping systems with significant root activity between 2-4 meters 
  • Develop unique facilities for deep root research for this project, for inspiration and for attracting cooperation with other scientists - also after the project period. 
  • Develop and test new methods for studying root growth and resource uptake (water and different plant nutrients) from deep soil layers (1-5 meters depth) 
  • Quantify potential use of resources from deep soil layers by different species and cropping systems and assess the potential environmental improvements in terms of nutrient cycling 
  • Study the effect of deeper and more permanent rooting on soil carbon storage and develop DNA based methods for understanding root interaction with soil biology in deep soil during growth and subsequent decomposition 
  • Create and communicate a compelling and accessible narrative on the biological and environmental value of deep root growth.
