Biochar-amended soil for resilient agriculture, soil health and climate change mitigation- An Integrated Assessment

Newcastle University offers a PhD project on biochar-amended soil aimed at enhancing soil health and resilience against climate change. The research focuses on the ecological and chemical interactions of biochar in soils, addressing significant gaps in understanding its long-term effects. Students will collaborate in an interdisciplinary environment, gaining mentorship and access to advanced research facilities. The position promotes diversity and inclusion within its academic community.
Background: Biomass releases greenhouse gas emissions through natural decay or when burnt. Processes such as pyrolysis, a thermochemical conversion of biomass, converts carbon dioxide captured in biomass into a stable, carbon-rich product called biochar, which can act as a soil carbon sink for hundreds of years with a potential to remove up to 6.6 Gigatons of carbon dioxide equivalent annually. Biochar is recognised by the United Nations Intergovernmental Panel for Climate Change as a carbon dioxide removal technology and offers a wide range of co-benefits in applications such as wastewater treatment, crop productivity increase and soil health. To adapt to increasing and accelerating changes in climatic conditions creating climate extreme events such as droughts and floods, we need more resilient crops and better soil health. While biochar production has increased significantly in the last few years, there is a significant gap in understanding the how’s and why’s of long-term and shot-term effects of biochar addition to soils, especially from an integrated assessment of abiotic and biotic interactions. Novelty and timeliness of the project: The proposed PhD project offers a unique opportunity for aspiring researchers to contribute significantly to mitigating climate change—a pressing global challenge. Biochar is recognised by the United Nations Intergovernmental Panel for Climate Change as a carbon dioxide removal technology and offers a wide range of co-benefits in applications such as wastewater treatment, crop productivity increase and soil health. To adapt to increasing and accelerating changes in climatic conditions creating climate extreme events such as droughts and floods, we need more resilient crops and better soil health. The project focuses on exploring ecological, micromechanical, and physico-chemical interactions in biochar-amended soils—a cutting-edge approach to understanding and enhancing soil resilience in the face of climate change. The project's holistic perspective, addressing both abiotic and biotic interactions, responds to the current gap in understanding the comprehensive impacts of biochar on soils. Your environment: The project fosters an interdisciplinary research environment, which is highly attractive to candidates seeking diverse and holistic scientific experiences. The student will collaborate at the intersection of engineering, chemistry, microbiology, and soil science, gaining a broad skill set that is invaluable for future research and career prospects. As part of this project, the student will collaborate with experienced supervisors and gain access to world-class research facilities on biochar and soil science at Newcastle University. This provides a unique opportunity to work alongside experts in the field, fostering mentorship and collaboration that can accelerate research progress and skill development.
