The amendment of soil with biochar has attrached attention for two main reasons. Firstly, biochar is an inert form of carbon that is highly
recalcitrant to microbial degradation, particularly when compared against the feedstocks it has been produced from. Hence, carbon, initially taken from the atmosphere to grow the feedstock used for biochar production,
then becomes locked into biochar which is then added to the soil - a form of carbon sequestration.
Additionally, biochar can help improve the fertility of the soils, allowing for enhanced plant growth and resiliance. Biochar can
benefit plant growth as a result of several complementary effects including: increasing carbon stocks, increasing nutrient availability, and allowing for an improved environment for Arbuscular mycorrhizal fungi to proliferate.
These fungi exist in a symbiotic relationship with plant roots, allowing for the update of increased amounts of nutrients by the plants.
