AI can now count soil fungi automatically, speeding up plant nutrition research

Mycorrhizal Networks
Every vegetable you grow is quietly negotiating with soil fungi that ferry phosphorus to its roots in exchange for sugar, and better measurement tools mean scientists can finally tell us which garden practices strengthen or break that deal.
Plants form partnerships with underground fungi that help them absorb nutrients from the soil. For decades, scientists had to count these fungi by hand under a microscope, which was slow and inconsistent. New computer tools, including some powered by artificial intelligence, can now do this automatically from photos, making it much easier to study what helps or harms these important plant-fungi relationships.
Key Findings
The review synthesizes studies on AMF colonization quantification published from 2001 to 2026, covering both traditional and emerging image-based methods.
Deep learning tools such as AMFinder, TAIM, and Mask R-CNN represent the cutting edge, offering automated, high-throughput root colonization assessment compared to manual gridline intersection counting.
Comprehensive reviews specifically focused on image-based AMF quantification methods remain scarce, leaving a guidance gap that this paper directly addresses for non-expert researchers.
chevron_right Technical Summary
Scientists have reviewed and compared a range of tools, from old-school manual counting to modern AI, for measuring how well beneficial soil fungi colonize plant roots. The review helps researchers pick the right method for their needs, with machine learning approaches showing the most promise for fast, accurate, consistent results.

From manual scoring to machine learning: recent developments in image-based arbuscular mycorrhizal fungi root quantification.
Selecting an appropriate method to quantify arbuscular mycorrhizal fungi (AMF) colonization in plants can be challenging, particularly for non-experts, due to the wide diversity of available techni...

Soil health is the capacity of soil to function as a living ecosystem, supporting complex interactions between microorganisms, soil fauna, and plant communities. For plant science, soil health is critical because these biological and chemical soil properties directly control nutrient availability,
