Mycorrhiza, selection software, agroinformatics, symbiosis optimization, AMF inoculants 1. Introduction Arbuscular mycorrhizal fungi (AMF) form mutualistic associations with over 80% of terrestrial plants, enhancing water and nutrient acquisition in exchange for photosynthetic carbon (Smith & Read, 2008). Despite this potential, commercial mycorrhizal inoculants often fail in the field due to a mismatch between the fungal species selected and the specific crop–soil–climate context (Hart et al., 2018). | Crop | Soil pH | T2 Colonization

where ( N_studies ) is the number of positive citations and ( MD_host ) is the mycorrhizal dependency score (0–1). Fungi with ( C_hf < 0.3 ) are excluded. User-input soil data (pH, %OM, P-availability) is compared against each fungus’s tolerance range. For each environmental variable ( e ), a membership function ( \mu_e ) is defined:
