This study investigated the effects of combining chemical fertilizer and fulvic acid (FA) organic fertilizer on soil enzyme activity, bacterial communities, and peanut yield. Seven treatments were established using the peanut cultivar Shanhua No. 9: no fertilization control (CK), conventional chemical fertilizer (A), 100% FA (B), 20% FA + 80% chemical fertilizer (C), 40% FA + 60% chemical fertilizer (D), 60% FA + 40% chemical fertilizer (E), and 80% FA + 20% chemical fertilizer (F).High-throughp
