Agronomy, Journal Year: 2025, Volume and Issue: 15(1), P. 124 - 124

Published: Jan. 6, 2025

This study examines the influence of grazing intensity on soil microbial communities in a desert steppe ecosystem. Soil samples were collected from three depths (0–10 cm, 10–20 and 20–30 cm) under varying intensities: control (CK), light (LG), moderate (MG), heavy (HG). Key physicochemical properties plant characteristics analyzed alongside diversity community composition, which assessed by identifying amplicon sequence variants conducting linear discriminant analysis effect size. The results showed that significantly impacted moisture, organic carbon, total nitrogen, phosphorus levels, with notable decrease cover grazing. CK LG treatments supported higher diversity, especially surface layers, while was associated shift composition toward stress-tolerant taxa like Acidobacteriota Blastocatella. Non-metric multidimensional scaling revealed differences structure between depths, effects diminishing depth. These findings highlight critical role sustainable practices maintaining health implications for long-term resilience ecosystems.

Influence of Cover Crop Root Functional Traits on Sweet Potato Yield and Soil Microbial Communities

Microorganisms, Journal Year: 2025, Volume and Issue: 13(3), P. 471 - 471

Published: Feb. 20, 2025

The symbiotic relationship between cover crops and soil microorganisms is closely linked to nutrient cycling crop growth within agroecosystems. However, how with different root functional traits influence microbial communities, properties, yields has remained understudied. This study assessed the of hairy vetch (HV) rapeseed (RP), along sweet potato yield, enzyme activity under red dryland conditions. High-throughput sequencing was also employed characterize diversity, composition, network structure bacterial fungal communities. According plant economic spectrum theory our research results on traits, HV can be identified as a resource-acquisitive crop, RP treatment resource-conservative crop. Although did not significantly increase rate reached 8.49%. Resource-conservative were associated increased pH, SOC, TP, which enhanced species diversity boosted populations Chloroflexi Alphaproteobacteria. In contrast, promoted proliferation Gammaproteobacteria. Network analysis indicated that facilitated complexity through intensified intra-community competition. Resource-acquisitive stability Collectively, these findings underscore distinct advantages varying in shaping Appropriate rotations effectively regulate communities hold potential enhance yield.

Assessment of some biological properties of soils across selected farming communities of Southern and Northern Nigeria

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: March 6, 2025

Background and Aims: This study examines the impact of soil biological parameters on agricultural productivity sustainability across Nigeria's diverse climates. Materials Methods: A multistage sampling method was adopted to collect 108 samples from four southern northern Nigeria locations, three communities, farmers' fields replicated times in a Complete Randomized Block Design (RCBD). Each sample analyzed for initial physicochemical some selected microbial properties. Results: In humid regions, activity high Location 1 (L1), with bacterial densities reaching 12.31 x 10⁷ CFU/ml associated fungal yeast at 1.55 10⁶ SFU/ml 5.08 counts, respectively. indicates bacterial-dominated ecosystem favourable rapid nutrient cycling, although it may risk structure over long term if unmanaged. Conversely, 3 (L3) drier areas showed less 9.83 but higher populations. suggests more environment that could enhance cycling structure, which is essential arid regions. The also investigated how environmental factors farming practices influence balances through hierarchical clustering analysis. Clusters like L3C1F2 L3C2F3 demonstrated balanced ecosystems substantial populations, supporting robust health. Conclusion: research highlights need precise, region-specific accommodate local profiles optimize crop yields sustain health, enhancing food security economic stability Nigeria.

Utilizing Microbial Inoculants to Alleviate Continuous Cropping Obstacles: Insights into the Metabolites and Transcriptomic Responses of Pinellia ternata

Metabolites, Journal Year: 2025, Volume and Issue: 15(3), P. 189 - 189

Published: March 11, 2025

Pinellia ternata (Thunb.) Breit is a widely used medicinal herb in Traditional Chinese Medicine (TCM). Still, its sustainable cultivation threatened by continuous cropping obstacles, which disrupt soil ecosystems, reduce yield, and degrade quality. Objectives: This study explores the potential of microbial inoculants to mitigate these challenges through integrated metabolomic transcriptomic analyses. Methods: Soil samples from fields with without issues were compare effects on secondary metabolism gene expression P. ternata. Results Discussion: Metabolomic profiling identified 20,969 metabolites, significant changes lipid-like molecules (22.2%), organic acids (9.1%), phenylpropanoids (7.0%) under treatment. Notable increases phenylalanine caffeic acid levels observed microbial-inoculated plants. Correspondingly, analysis revealed upregulation ammonia-lyase (PAL) other stress-related genes, confirming metabolic shifts. Clustering machine learning analyses highlighted critical roles metabolites genes enhancing plant resilience. Microbial improved metabolite production. Implications: These findings provide valuable insights into mechanisms microbial-plant interactions establish approach for cultivating ternata, addressing while improving crop productivity

Livestock Slurry and Sustainable Pasture Management: Microbial Roles, Environmental Impacts, and Regulatory Perspectives in Ireland and Europe

Microorganisms, Journal Year: 2025, Volume and Issue: 13(4), P. 788 - 788

Published: March 29, 2025

Pastures serve as the primary source of grass and forage plants for grazing livestock, requiring adequate nutrient input to sustain growth soil fertility. Slurry from livestock industry is widely utilized a sustainable cost-effective alternative chemical fertilizers. Microorganisms within slurry–pasture system are essential breaking down organic matter, facilitating cycling, improving health. However, mismanagement or inefficient microbial decomposition can lead significant issues, such leaching into water bodies, causing eutrophication, antimicrobial resistance, reduced availability in pastures, which, turn, may negatively impact productivity. Thus, this paper investigates composition benefits slurry pasture management, highlights roles evaluates regulatory frameworks Ireland Europe. Additionally, it examines environmental risks associated with improper application, providing insights support management practices.
