Biochar and Fungi Benefit Drought Stressed Plants

Interactions between biochar and mycorrhizal fungi in a water-stressed agricultural soil

Australian scientists developed a unique way to see how biochar helps in times of drought.  A soil chamber that used fine mesh to separate sides was used to see just how far mycorrhizal fungi will go to help out.   They saw adding biochar helped the beneficial mycorrhizal fungi to colonize plant roots.  Under the water stress conditions, the biochar treated soil grew plants with longer shoots with higher phosphorus content.  This matched up with what they saw underneath the microscope.  The biochar soil had more fungi-root colonization, with longer fungal hyphae.
