Nano-Biochar-Assisted Intercropping Alleviates Fusarium Wilt of Faba Bean by Enhancing Rhizosphere Soil Health in Long-Term Continuous Cropping Soil.

Nano-biochar combined with intercropping reduces Fusarium wilt incidence in faba bean by up to 50% in long-term continuous cropping soil.

• Why it matters: Faba bean monocropping degrades soil and increases disease risk, highlighting the need for sustainable strategies to manage soil health and disease suppression in continuous cropping systems.
• What they did: A pot experiment compared monocropping and intercropping under control, biochar, and nano-biochar treatments, assessing disease incidence, soil properties, enzyme activities, and microbial communities.
• The result: The combined intercropping and N-BC treatment improved soil health indicators, increased beneficial bacteria like Pseudomonas, decreased Fusarium abundance, and significantly reduced disease measures, supporting a sustainable soil management approach.
