Disentangling community assembly processes is crucial for fully understanding the function of microbiota in agricultural ecosystems. However, numerous plant microbiome surveys have gradually revealed that stochastic dominate endophytic root conflict with strong host filtering effects, which an important issue. Resolving such conflicts or inconsistencies will not only help accurately predict composition and structure its driving mechanisms, but also provide guidance on correlation between relative importance deterministic microbiota, crop productivity nutritional quality. Here, we propose inappropriate division dispersal limitation may be main reason inconsistency, can resolved after proportion incorporated into processes. The rationality this adjustment under framework formation a holobiont herein explained, potential theoretical dynamic patterns along soil–plant continuum proposed. Considering complicated, suggest caution level-by-level verification from to neutral components when deciding attribution future promote expansion application engineering sustainable development based patterns.

Organic fertilizers, such as spent mushroom substrate (SMS), improve soil fertility, but studies comparing their effects on different agricultural soils are limited. In this study, the of standard, SMS and composed fertilizers from conventional-integrated, organic biodynamic farming were investigated. Soil samples analyzed for microorganisms activity β-glucosidase (β-GLU), β-1,4-N-acetylglucosaminidase (NAG), urease (URE), arylamidase (ARN), phosphatase (PHOS), acid (PAC), alkaline (PAH) arylsulphatase (ARS). Biodynamic showed highest microbial counts enzyme activities, followed by conventional soils. significantly increased number especially in Seasonal variations affected all most enzymes soils, except NAG stable throughout year, indicating greater stability. This study concludes that activities respond differently to fertilization depending type, with demonstrating beneficial tested
