Eusun Han

Eusun Han from Republic of Korea was a Postdoc Fellow and an agronomist at the Department of Plant and Environmental Sciences, University of Copenhagen. 

Eusun joined the DeepFrontier project in 2016 at the very beginning phase of the field trial at DeepRootLab. He has developed a root research method, called the the Core-labelling technique (CLT) that has been successfully implemented and verified over the last 3 years, which is now being utilized by other researchers under the project. Determination of root growth and activity as affected by management strategies is a key research focus of Eusun, to which he contributed as follows: 

  • Designing and implementing CLT by combining the ingrowth-core and tracer-labelling methods for field investigation.
  • Testing tracer-labelling of stable isotopes (15N and 18O-PO4), radioactive isotope (33P) and nutrient analogues (Li, Cs, Se, Rb, Sr) against multiple depth-(from 0.2 to 4.2 m) and time-scales (from 14 days to 60 days).
  • Comparing over 12 deep-rooting crop species and 3 strip-intercropping systems for root growth and nutrient acquisition potential.
  • Quantifying root depth, density, morphology and architecture using advanced image-analysis such as Convolutional Neural Network (CNN).

Under the DeepFrontier project, Eusun has accumulated a vast amount of experience in root research in situ. Upon witnessing deep roots’ potential for crop resource acquisition, he believes that utilizing the strategy of “growing more and deeper roots” can contribute to sustainable intensification of farming systems.

Eusun commenced at University of Copenhagen on April 2, 2016 and finished his studies on May 28, 2020.
