Effects of Arbuscular Mycorrhizal Fungi on Leaf N: P: K Stoichiometry in Agroecosystem

Leaf nitrogen (N), phosphorus (P), and potassium (K) stoichiometry can reflect plant strategies of nutrient allocation, which play key roles in ensuring food security maintaining balance the agroecosystem. Arbuscular mycorrhizal fungi (AMF) inoculation is an effective green management measure affecting uptake utilization strategies, especially However, interplay between AMF leaf that important for sustainable agriculture remain underexplored. Therefore, efficacy improving nutrients host plants agricultural ecosystems were tested with meta-analysis by 1932 pairs observations research publications from 1995 to 2022. Overall analysis showed increases N, P, K 8.75%, 24.61%, 13.54%, respectively. Moreover, P: increased 11.74% inocula, but N: P decreased 15.38% 5.52%, Furthermore, effect on was significantly regulated species, life cycle, growth habits plants. The prominent higher fruit (30.06%), perennial (30.19%), woody (31.6%) than other groups. effects inoculated crops varied depending identity AMF. Glomeraceae (especially Rhizophagus genera) more content families. Thus, related habits, These findings highlight response provide a theoretical applicable way better crop yield agriculture.
