Living grass mulching (LGM) is an important orchard floor management that has been applied worldwide. Although LGM can effectively enhance soil nutrient availability and fertility, its effects on microbial-mediated cycling main drivers are unclear. Meanwhile, the variation of enzyme activities with duration have rarely studied. This study aims to explore age layer nutrients in citrus orchards. In this study, three (Vicia villosa) treatments were applied, i.e., for eight years, four no (clean tillage). Their analyzed different layers orchards subtropical China, 0-10, 10-20, 20-40 cm. Compared clean tillage, years had fewer nutrients. contrast, significantly increased available nitrogen (N), phosphorus (P) nutrients, β-glucosidase, cellobiohydrolase 0-20 0-40 cm, microbial biomass carbon (C), N, P, N-acetylglucosaminidase, leucine aminopeptidase, acid phosphatase also (P < 0.05). Mulching promoted C, P-cycling total by 2.45-6.07, 9.29-54.42, 4.42-7.11, 5.32-14.91 times, respectively. Redundancy analysis shows layer-dependent positive activities. Microbial C P showed most significant correlation activities, followed moisture content, organic N Available contributed almost 70% affect activity variation. summary, could improve increasing The promotion effect was more under years.

Abstract Biochar and organic fertilizer are widely supported to maintain crop production sustainable development of agroecosystems. However, it is unclear how biochar alone or in combination regulate soil functional microbiomes their relationships ecosystem multifunctionality (EMF). Herein, a long-term (started 2013) field experiment, containing five fertilization treatments, was employed explore the effects applications on EMF (based 18 indicators productivity, nutrient supply, element cycling, microbial biomass) bulk rhizosphere [normalizing abundances 64 genes related carbon (C), nitrogen (N), phosphorus (P), sulphur (S) cycles]. Compared with single-chemical fertilization, inputs significantly enhanced most ecosystem-single functions and, particular, increased by 18.7–30.1%; taxa C-N-P-S cycles varying degree. The combined application showed better improvement these compared using them individually. Most populations soil, especially involved C degradation, nitrification, nitrate-reduction, P mineralization, S cycling positive associations at different threshold levels, which ultimately regulated pH availability. These results highlight strong links between agroecosystem functions, as well providing scientific support for inclusion agricultural services amendments. Graphical

As an essential agroforestry, intercropping legumes can improve the physical, chemical, and biological fertility of soil in tea plantations. However, effects different legume species on properties, bacterial communities, metabolites remain elusive. In this study, 0-20 cm 20-40 soils three planting patterns (T1: plants/mung bean intercropping, T2: plants/adzuki T3: adzuki intercropping) were sampled to explore diversity community metabolites. The findings showed that, as compared monocropping, systems had greater concentrations organic matter (OM) dissolved carbon (DOC). Notably, pH values significantly lower, nutrients increased with monoculture soils, especially T3. addition, resulted relative abundance Proteobacteria but a decreased Actinobacteria. 4-methyl-Tetradecane, acetamide, diethyl carbamic acid key mediating root-microbe interactions, bean, mixed soils.

Microorganisms play essential roles in soil-ecosystem multifunctionality. However, the contribution of their community assembly processes, composition, diversity, and keystone species to ecosystem multifunctionality is unclear, especially tea-plantation ecosystems. In order assess effects various intercropping patterns (tea-plant monoculture tea plants, respectively, intercropped with soybean, soybean—milk vetch, soybean—red clover, soybean—smooth vetch) on soil rare abundant taxa, a field experiment was carried out. We found that plantation legumes improved by altering environment, ultimately benefited nutrient absorption quality improvement leaves. Whether it bacteria or fungi, taxa had higher proportion deterministic processes than taxa. Additionally, practices changed bacterial were assembled shifted from variable selection homogeneous dispersal.
