In this study, the accumulation characteristics of As, Hg, Cd, Cr, and Pb in 63 soil samples from 28 organic farms Beijing, China, were analyzed to investigate risk heavy metal pollution agriculture, key related factors evaluated. The results revealed that concentrations below screening values substantially lower than those under conventional agriculture. However, coefficients variation for Hg Cd 112.45% 38.34%, respectively, indicating a notable anthropogenic impact. Notably, 35.92% sampling sites had medium high potential ecological concentration increased considerably as number planting years increased. Different crop types impacted concentrations. As Brassica crops 0.265 12.915 mg/kg, which higher other types. Random Forest model indicated nutrients most significant impact on accumulation, particularly phosphorus. conclusion, compared with agricultural soils have exhibit risks, no detected. there is preventive measures should be implemented, especially prolonged cultivation sources inputs.

Teosinte-derived SynCom and precision biofertilization modulate the maize microbiome, enhancing growth, yield, and soil functionality in a Mexican field

Frontiers in Microbiology, Год журнала: 2025, Номер 16

Опубликована: Апрель 9, 2025

Modern agriculture faces the challenge of optimizing fertilization practices while maintaining soil resilience and microbial diversity, both critical for sustainable crop production. We evaluated effects multiple strategies on communities plant performance, comparing conventional methods (urea-based phosphorus fertilizers applied manually or via drone-assisted precision delivery) with biofertilization using a synthetic consortium (SynCom) derived from teosinte-associated microbes. This SynCom consisted seven bacterial strains: Serratia nematodiphila EDR2, Klebsiella variicola EChLG19, Bacillus thuringiensis EML22, Pantoea agglomerans EMH25, EBG39, marcescens EPLG52, tropicus EPP72. High-throughput sequencing revealed significant shifts in fungal across treatments. Untreated soils showed limited dominated by Enterobacteriaceae (>70%). Conventional gradually reduced increasing Pseudomonas Lysinibacillus populations. Drone-assisted notably enhanced Acinetobacter Rhizobiales growth. Biofertilization treatments produced most pronounced shifts, reducing below 50% significantly beneficial taxa like Bacillus, Pantoea, Serratia. Network analysis demonstrated that interaction complexity increased treatments, emerging as keystone species. fostered particularly intricate networks, enhancing synergistic relationships involved nutrient cycling biocontrol, though stability these complex interactions requires careful monitoring. Our findings provide key insights into how teosinte-derived consortia can sustainably reshape maize microbiome, improving performance resilience.

Deciphering the rhizosphere microbiota composition of nature farming soybean (Glycine max L.) with different nodulation phenotypes

BMC Plant Biology, Год журнала: 2025, Номер 25(1)

Опубликована: Апрель 24, 2025

Nature farming, a sustainable agricultural method which avoids agrochemicals and untreated organic amendments, promotes both productivity ecological conservation. This system may foster unique plant-microbiota interactions for growth fitness; however, the microbiota of nature-farmed plants remains largely unexplored. Second, root nodule symbiosis (RNS) is crucial nitrogen fixation in legumes; its broader impact on rhizosphere assembly not well understood. study examined dynamics between impaired symbiosis, soil management, composition soybean (Glycine max L.). We evaluated characterized bacterial fungal communities by comparing wildtype soybeans (Enrei) with non-nodulating mutants (En1282) across four soils under conventional nature including fumigated unfumigated conditions. found that exhibited reduced compared wild-type plants, especially soils. Soil fumigation decreased microbial diversity reshaped community significant reduction plant nodulation all Restriction RNS increased soils, possibly as compensatory mechanism acquisition, whereas remained relatively stable. farming promoted beneficial microbes like Rhizobium, Trichoderma, Chloridium, favored Bacillus Aspergillus. Notably, differential enrichment analysis identified distinct associations each phenotype, Enrei predominantly enriched Pseudomonas, En1282 associated primarily oligotrophic microbes. Our sheds light complex interplay legume highlights significance eco-friendly methods cultivating healthy growth. The results paves way future strategies to manipulate microbiota, ultimately promoting robust systems reduce reliance chemical inputs.

Conventional and organic farms with more intensive management have lower soil functionality

Science, Год журнала: 2025, Номер 388(6745), С. 410 - 415

Опубликована: Апрель 24, 2025

Organic farming is often considered to be more sustainable than conventional farming. However, both systems comprise highly variable management practices. In this study, we show that in organic and arable fields, the multifunctionality of soils decreases with increasing agricultural intensity. Soil carbon content bacterial biomass, respectively, were strongest abiotic biotic predictors soil multifunctionality. Greater was associated less-frequent inversion tillage higher frequency grass-legume cover cropping, did not outperform Our results suggest reducing intensity will enhance This implies that, contexts where high-yielding, high-intensity agriculture prevails, paradigm intensification should replaced by “productive deintensification.”

Effect of Seasonal Variations on Soil Microbial, Extracellular Enzymes, and Ecological Stoichiometry in Tea Plantations

Ecology and Evolution, Год журнала: 2025, Номер 15(5)

Опубликована: Май 1, 2025

ABSTRACT Tea plantations are important agricultural ecosystems in karst areas, yet the seasonal dynamics of soil microbial communities, functional genes, and extracellular enzyme activities (EEA) under different management practices remain poorly understood. This study investigated organic (HY), pollution‐free (TS), conventional (XY) tea Weng'an County, Southwest China, during spring (April) autumn (August) seasons via metagenomics stoichiometric analyses. Seasonal variations significantly altered physicochemical properties (e.g., SOC, TN, TP) EEA ( p < 0.05), with higher C‐acquiring activity elevated C:N:P ratios spring. The stoichiometry (EES C:N:P) deviated from theoretical 1:1:1 ratio, indicating that metabolism was constrained by resource availability rather than homeostasis. Phosphorus limitation (vector angle > 45°) persisted across seasons, contradicting initial hypotheses, acid phosphatase (ACP) EES C:P identified as critical drivers. Random forest (RF) structural equation modeling (SEM) revealed season had stronger impacts on communities C:N, NAG, ACP, key predictors. Compared practices, enhances diversity redundancy, buffering fluctuations. These findings highlight interplay between climatic shifts regulating nutrient cycling adaptation. Strategic interventions—such carbon supplementation, phosphorus fertilization, intercropping—are proposed to optimize resilience ecosystem stability fragile plantations. provides novel insights into ecological metabolic strategies, offering a reference for sustainable agroecosystems areas.
