To discriminate the transport characteristics of residue-derived carbon (Cres) from soil native (Csoil) in black with split nitrogen application, a 540-day incubation study was conducted four treatments: Control (unamended soil), R (soil + residue), RN1 residue one-time application fertilizer), and RN3 three-time fertilizer). The total organic (TOC) incubated separated into three fractions: light fraction (LF), occluded-particulate matter (OPOM), heavy (HF). results showed that TOC content...

Dissolved organic matter (DOM) plays a critical part in many processes of the ecological environment due to its mobility and reactivity soil water interface. In presented study, excitation-emission matrices (EEM) coupled with parallel factor analyses (PARAFAC) UV-visible spectroscopy were introduced investigate variation DOM derived from wheat straw biochar produced at different pyrolysis temperatures (300 °C, 500 °C 700 °C), qualitatively quantitatively. The dissolved content achieved...

(1) Background: environmental gradient strongly affects microbial biodiversity, but which factors drive the diversity of arbuscular mycorrhizal fungi (AMF) associated with roots at relatively large spatial scales requires further research; (2) Methods: an experiment on Mt. Taibai was conducted to explore biodiversity and drivers AMF-associated using high-throughput sequencing; (3) Results: a total 287 operational taxonomic units (OTUs) belong 62 species representing 4 identified 1...

Medicinal plants are invaluable resources for mankind and play a crucial role in combating diseases. Arbuscular mycorrhizal fungi (AMF) widely recognized enhancing the production of medicinal active ingredients plants. However, there is still lack comprehensive understanding regarding quantitative effects AMF on accumulation ingredients. Here we conducted global analysis using 233 paired observations to investigate impact inoculation This study revealed that significantly increased contents...

Mycorrhizal strategies include mycorrhizal statuses and types, which are important reflections of the functional characteristics ecosystems. The stoichiometry carbon, nitrogen, phosphorus in plant organs is an part ecosystem functions, has impact on nutrient cycle ecosystem. concentration played a crucial role functioning dynamics. purpose this study to provide theoretical basis data support for improving properties global terrestrial ecosystems by exploring C, N, P different shrub organs....

Leaf nitrogen (N), phosphorus (P), and potassium (K) stoichiometry can reflect plant strategies of nutrient allocation, which play key roles in ensuring food security maintaining balance the agroecosystem. Arbuscular mycorrhizal fungi (AMF) inoculation is an effective green management measure affecting uptake utilization strategies, especially However, interplay between AMF leaf that important for sustainable agriculture remain underexplored. Therefore, efficacy improving nutrients host...

The mycorrhizal traits of plants have been widely reported based on different scales or plant functional groups. To better utilize mycorrhizae to improve the cultivation yield and active ingredient accumulation medicinal plants, a database characteristics is needed. A including type status Chinese species was assembled. In this study, total 3,230 presented. Among them, 1,321 were ascertained. These had three statuses, both single mycorrhiza (SM) multi-mycorrhiza (MM) contained four types....

Mycorrhizal types are a predictive framework for nutrient cycling within and across ecosystems, their represent different nutrient-acquisition strategies plants. Carbon (C), nitrogen (N) phosphorus (P) stoichiometric ratios essential understanding biogeochemical processes. The purpose of this study was to reflect the balance in process plant resource acquisition by exploring C, N P (C/N, N/P, C/P) shrub organs mycorrhizal types. In study, N, leaves, stems roots were analyzed arbuscular (AM),...

Dissolved organic matter (DOM) has a critical impact on various processes in the ecological environment, especially soil and surface water due to its mobility reactivity. In present study, column experiment simulating paddy field was conducted evaluate feasible application of inorganic fertilizer incorporated with three types materials (wheat straw, rapeseed shell, astragalus smicus). Researchers investigated vertical distinctions (combined different 0–10 cm) DOM 0–40 cm profiles after...

The application of biochar in conjunction with fertilizer agricultural production is one the most promising types management to improve soil quality. However, effects on microbial community and methane (CH 4 ) emissions from interactive mechanisms combined are unclear. In this study, column trial was conducted monitor surface water nitrogen, dissolved organic carbon (DOC) CH emission dynamics during process leaching. Additionally, bacterial archaeal communities (0-10 cm) amended derived...

Fine roots are essential for terrestrial biogeochemical cycles. Mycorrhizal fungi’s functions in regulating the uptake of carbon (C), nitrogen (N), and phosphorus (P) plants increasingly being recognized. However, influence mycorrhizae on Chinese plants’ fine-root stoichiometry has not been considered. Herein, 772 with identified mycorrhizal types were divided into arbuscular (AM) ectomycorrhizal (ECM) to investigate differences their driving factors. The results showed that AM ECM...

Methane produced from paddy fields has a negative impact on global climate change. However, the role of soil bacterial community composition in mediating methane (CH4) emission waterlogged using column experiment is poorly known. In present study, various fertilization treatments were adopted to investigate effects fertilizer reduction combined with organic materials (CK: control; CF: conventional fertilization; RF: 20% reduction; RFWS: RF plus wheat straw amendment; RFRS: rapeseed shell...

Arbuscular mycorrhizal fungi (AMF) can form symbionts with plant roots, acquire soil nitrogen, and affect nitrous oxide (N2O) production. Biochar, as a additive for the management of agricultural soil, affects nitrogen (N) utilization growth. However, how AMF regulates N unitization, denitrification process, N2O emissions in plant–soil systems remains largely unknown, particularly under biochar amendment. In this study, microcosm experiment was conducted to investigate impacts different...
