UC2 SOIL HEALTH AND ROOT PHENOTYPING

Innovative, automatable soil imaging techniques to determine key belowground parameters in real time at plot to landscape scale

Partners: BOKU (Lead), UPorto, S4ML

Objective

UC2 SOIL HEALTH AND ROOT PHENOTYPING
Subterra Green prototype (TRL 5-6) from S4ML

The UC will deliver an innovative approach for the in situ quantification of soil physico-chemical and root properties, which are often missing in agricultural and ecological applications or surveyed at coarse resolutions.

It will utilize portable, high-performance near infrared (NIR) instruments, increasingly established as a rapid and cost-efficient laboratory technique, taking the technique from the laboratory to the field for fast, automatable on-site surveys of key soil parameters such as soil organic carbon (Figure X). Specifically, the UC will:

Work flow for Modelling and integration of hyperspectral and Root detecting RGB probes to a user-friendly interface
  • Determine dependency of calibrations (on ground truthing data) on soil type, texture, moisture & rooting densities.

  • Develop analysis pipelines and a User Interface for use in RI.

  • Relate surface measured by unmanned aerial vehicles (UAV) and deep soil C pattern for upscaling soluble organic compounds (SOC) at landscape levels and define sampling strategies (probe insertion, and ground truthing) for heterogeneous landscapes.

  • Link ex situ soil spectral libraries to in situ spectra.

  • Develop ontology, data format, (European) ex situ spectral library.

  • Train-the-trainer courses for a wide adoption of the techniques.

Expected results and services

  • Spectral probe application in European agroecosystems.
  • Application of new root probe for breeding climate-smart crops.
  • Landscape-scale, deep soil C mapping.
  • Method publication on relation between in situ / ex situ soil spectra.
  • Method and data publication on new ex situ soil spectral library.
  • Co-creation of ready-to-use soil spectroscopy and root imaging module, ready for robotic automation.
  • New, FAIR ex-situ soil spectral library to be used by multiple stakeholders.
  • User interface for RI + stakeholders to operate, re-train (models of) the soil and root probe device; RIs include new services in their catalogue.
  • User interface and model to select effective sampling designs for landscape wide C mapping.
  • 4ML leverages on the project to develop, provide new services to customers.
