Organic amendments are widely used to enhance soil fertility and nutrient cycling in greenhouse cultivation, but their effectiveness can vary depending on origin composition. This study investigated the impact of four organic materials (rice husk, coconut coir, biochar, sheep manure) enzyme activities two tomato soils. The distribution nutrients was analyzed under controlled conditions during a pot experiment. addition amendments, regardless source, significantly altered microbial resource allocation, reducing carbon limitation while increasing nitrogen demand. effect pools largely determined by chemical composition amendments. In clayey soils, biochar rice husk additions most effectively promoted related carbon, nitrogen, phosphorus acquisition. Under sandy conditions, manure increased acquisition enzymes, enhanced enzymes. Biochar emerged as particularly effective amendment, enhancing sequestration across different types. specifically, content carboxyl C, aromatic O-alkyl played crucial role influencing limitations. mean C:N:P ratios for CK, T1, T2, T3, T4 treatments were 1:1.375:0.625, 1:1.244:0.662, 1:0.839:0.610, 1:1.161:0.689, 1:1.038:0.549, respectively. 1:1.117:0.698, 1:1.18:0.75, 1:1.096:0.731, 1:1.217:0.689, 1:1.06:0.669, These findings suggest that improve retention activities, effects influenced both texture. research enhances our understanding transformations, aids optimizing application improved management cultivation.

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.

Soil microbial biomass stoichiometry homeostasis is essential for microorganism survival and ecosystem stability. Despite its importance, research on soil in Natural World Heritage Sites (NWHS) lacking. This study analyzed ecological surface (0–20 cm) subsurface (20–40 soils across various vegetation types Fanjing Mountain, an NWHS China. The objective was to explore relation identify key influencing factors. Results indicated that higher than 5 types, mirroring nutrient but contrasting enzyme stoichiometry. Vector length (VL) suggests C limitation all while vector angle (VA) shows P of certain N types. Random forest analysis revealed the carbon-nitrogen ratio (MB C/N) mainly contributed by C/N (14.11 %), SOC (12.31 pH (10.52 NH4+-N, SWC, NO3--N soil, (15.74 altitude, SOC, whereas carbon-phosphorus C/P), altitude (12.16 SWC (9.86 AP were main contributing factors (10.49 C/P, TP. provides insights into stoichiometry, homeostasis, limitations aiding balance management NWHS.
