Biochar and plant-soil interactions

Evidence from short-term greenhouse studies and small-scale field trials suggests that the addition of biochar to soils promotes plant yield. This has stimulated much interest in developing biochar as an effective tool in sustainable food production while simultaneously storing more carbon in the soil. Belowground, root biomass can also be increased, but further detailed assessment is lacking. This project focuses on the mechanisms controlling biochar-root interactions and the subsequent effects within the complex soil environment, such as nutrient and moisture uptake efficiency, and the potential impact on important microbial processes (e.g. respiration, decomposition and denitrification).

Currently, the project is investigating the relationship between biochar application rates and root architecture and nutrient uptake.
