Mason, et al (2024) Response of wheat to arbuscular mycorrhizal fungiThese are friendly fungi that form a partnership with plant roots. They act like an extension of the root system, helping plants access water and nutrients more effectively. Biochar can create a cozy habitat for these helpful fungi, boosting their growth and improving plant health.   More inoculation and biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges.

A recent study explores the combined effects of biochar and arbuscular mycorrhizal fungi (AMF) on wheat growth and soil carbon dynamics. Conducted in a greenhouse setting, the research found that both biochar and AMF promote wheat biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More production. Notably, AMF inoculation significantly increased plant growth without impacting wheat yield, suggesting a potential strategy to enhance crop productivity.

The study also highlights biochar’s role in regulating fungal activity in the soil, contributing to a more balanced soil carbon dynamic. While biochar application did not directly increase soil carbon stocks beyond its contribution, it moderated fungal-driven carbon loss, showing its potential to stabilize soil carbon. AMF inoculation, though beneficial for plant growth, led to a reduction in direct soil carbon accumulation in non-biochar treated soils. This suggests that biochar and AMF together could create a pathway for soil carbon stabilization.

The findings have important implications for carbon sequestration practices, particularly within frameworks like the Australian Carbon Credit Scheme, where enhancing soil carbon storage is a priority. However, the study concludes that while biochar and AMF offer promising synergies for long-term soil carbon gains, further research is needed to fully understand their interactions over longer time periods.

By combining AMF and biochar, this research presents a potential strategy for improving agricultural productivity and soil carbon storage, supporting both environmental sustainability and climate change mitigation efforts.
