The role of biochar application in modifying soil architecture, root morphology and soil C dynamics – Debarati Bhaduri

Title: The role of biochar application in modifying soil architecture, root morphology and soil C dynamics

Project Description

Biomass-derived black carbon (or Biochar) has gained attention in recent times due to its interactions with soil properties. The study of root-biochar interactions provides an opportunity to study soil architecture, root morphology in rhizosphere, inter-linked with soil C dynamics and microbial responses that may give a new insight into the mechanisms of soil changes resulting from biochar application.

Approach

Based on a glasshouse experiment using different biochars the study aims to:

  • assess the changes in soil structural properties (pore geometry, soil aggregation network) and in root morphology brought by biochar application
  • study the differential response of biochar(s) regarding soil C dynamics, microbial responses, and gas exchange behaviour in the presence of plant roots to evaluate the potentiality of biochar to mitigate climate change.

Outcome

The study will help to develop a conceptual framework on root-biochar interaction encompassing these related aspects.
