ABSTRACT Despite extensive research on microbiota across land use gradients, it remains unclear if microbial co‐occurrence relationships exhibit consistent patterns. Here, we assessed networks of seven natural ecosystems— Quercus ilex forest, Fagus sylvatica Abies alba Mediterranean and mountain grasslands, subalpine shrublands—and five agroecosystems, including vineyards, horticulture, greenhouse, a polluted agricultural system, an arid greenhouse. Soil chemistry, such as pH, organic carbon total nitrogen, was characterised, soil were profiled using high‐throughput sequencing from 242 samples. Our results revealed that grasslands had the highest (86.4 g/kg), while greenhouse lowest (6.1 g/kg). pH 5.79, vineyards electrical conductivity 0.901 dS/m. Notably, ecosystem exhibited greater modularity, with protected horticulture showing exceptionally (0.937), intensive agriculture within agroecosystems significantly lower modularity 0.282. Modularity number modules positively correlated P 2 O 5 , network diameter, path length clustering coefficient pH. Additionally, edges nodes number, average degree diversity associated nitrogen. These findings highlight ecosystems foster more complex resilient networks, underscoring sustainable management's importance to preserve health diversity.
