Agroforestry ecosystems are an efficient strategy for enhancing soil nutrient conditions and sustainable agricultural development. Soil extracellular enzymes (EEAs) important drivers of biogeochemical processes. However, changes in EEAs chemometrics rubber-based agroforestry systems their mechanisms action still not fully understood. Distribution EEAs, enzymatic stoichiometry, microbial limitation characteristics rubber plantations under seven planting patterns (RM, monoculture system; AOM, Hevea brasiliensis-Alpinia oxyphylla Miq; PAR, brasiliensis-Pandanus amaryllifolius Roxb; AKH, katsumadai Hayata; CAA, brasiliensis-Coffea Arabica; CCA, brasiliensis-Cinnamomum cassia (L.) D. Don, TCA, brasiliensis-Theobroma Cacao) were analyzed to investigate the metabolic limitations microorganisms identify primary determinants that restrict limitation. Compared with systems, show increased carbon (C)-acquiring enzyme (EEAC), nitrogen (N)-acquiring (EEAN), phosphorus (P)-acquiring (EEAP) activities. The ecoenzymatic stoichiometry model demonstrated all plantation experienced C N system, exacerbated by reducing vector angle increasing length. P was detected any pattern. In progression from herbs shrubs trees through intercropping results a reduction constraints. This is primarily because accumulation litter root biomass tree-based which enhances content (e.g., organic carbon, total nitrogen, phosphorus, ammonium nitrogen) accessibility. Conversely, as depth increased, tended become more pronounced. Partial least squares path modelling (PLS-PM) indicated ratios most factors influencing (−0.46 0.40) (−0.30 −0.42). study presented novel evidence regarding constraints metabolism systems. Considering nutrients metabolism, arboreal species recommended over herbaceous better suit environment areas on Hainan Island.
