Published: July 3, 2023

Ecosystem functions and services are under threat from anthropogenic global change at a planetary scale. Microorganisms the dominant drivers of nearly all ecosystem therefore ecosystem-scale responses dependent on resident microbial communities. However, specific characteristics communities that contribute to stability stress unknown. We evaluated bacterial by generating wide experimental gradients diversity in soils, applying measuring several microbial-mediated processes, including C N cycling rates soil enzyme activities. Some processes (e.g., mineralization) exhibited positive correlations with losses resulted reduced processes. comprehensive evaluation potential revealed α per se was never among most important predictors functions. Instead, key included total biomass, 16S gene abundance, ASV membership, abundances prokaryotic taxa functional groups nitrifying taxa). These results suggest may be useful indicator function stability, but other stronger statistical better reflect biological mechanisms which influence ecosystems. Overall, our provide insight into role microorganisms supporting identifying critical for understanding predicting change.

Published: Dec. 2, 2023

Plant-associated microbiomes contribute to important ecosystem functions such as host resistance biotic and abiotic stresses. The factors that determine community outcomes are inherently difficult identify under complex environmental conditions. In this study, we present an experimental analytical approach explore microbiota properties relevant for a microbiota-conferred phenotype, here plant protection, in reductionist system. We screened 136 randomly assembled synthetic communities (SynComs) of five bacterial strains each, followed by classification regression analyses well empirical validation test potential explanatory structure composition, including evenness, total commensal colonization, phylogenetic diversity, strain identity. find identity be the most predictor pathogen reduction, with machine learning algorithms improving performances compared random classifications (94-100% versus 32% recall) non-modelled predictions (0.79-1.06 1.5 RMSE). Further confirms three main drivers reduction two additional confer protection combination.

Contribution of Eco-Friendly Agricultural Practices in Improving and Stabilizing Wheat Crop Yield: A Review

Agronomy, Journal Year: 2023, Volume and Issue: 13(9), P. 2400 - 2400

Published: Sept. 17, 2023

Wheat is considered to be a strategic crop for achieving food security. Wherefore, one of the current objectives today’s agriculture ensure consistent and sustainable yield this particular while mitigating its environmental footprint. However, along with genetic potential varieties, agricultural practices play key role in ensuring high stable wheat. Under changing climatic conditions, new eco-friendly were adopted wheat farming system recent decades. In review, large number peer-reviewed articles have been screened during last 15 years evaluate some environmentally friendly such as tillage system, biological protection, rotation, intercropping systems, integration resistant varieties yield. The present investigation unveiled that embracing methods holds engender yields, contingent upon normative strategy comprehensively addresses multiple factors. These include intrinsic attributes grown cultivars, plant nutritional parameters, soil agrochemical characteristics, specific conditions. Further in-depth investigations under field conditions are necessary help discernment appropriate techniques can efficaciously optimize different cultivated varieties.

The accumulation of carbon dioxide in the atmosphere due to fossil fuel burning and deforestation has caused global warming an increase extreme weather events. To complement shift towards clean energy, it is crucial adopt methods for removal, known as negative emission technologies. Enhanced weathering one such approach that involves accelerating natural process rock by spreading finely ground rocks over large areas, agricultural land or coastal areas. This exploratory review paper provides overview fundamental mechanisms behind enhanced weathering, outlines techniques its implementation. environmental benefits are highlighted, including improvement soil fertility. Furthermore, potential impacts on ecosystems biodiversity examined, along with effects water, air quality. also considers risks challenges associated large-scale implementation long-term stability weathering. Additionally, integration Sustainable Development Goals explored, co-benefits trade-offs other sustainability objectives. conclude, this summarizes key findings proposes avenues further research field

Effects of the tobacco–maize relay intercropping pattern on soil nutrients and soil microbial diversity

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 15

Published: Jan. 10, 2025

The imbalanced soil nutrient status caused by the long-term monoculture of flue-cured tobacco are a concern. tobacco-maize relay intercropping, widely used in Yunnan, may improve nutrients enhancing microbial community, but this remains unexplored. This study employed high-throughput sequencing technology to examine diversity under and using varieties Hongda K326, respectively. results indicated that intercropping significantly enhanced root biomass compared monoculture, with no significant effect on aboveground biomass. treatment also improved physicochemical properties, including pH, total phosphorus, available potassium, which was associated an increase community (as Chao1 Shannon indices). Specifically, abundance arbuscular mycorrhizal fungi, Nitrospira, Acidobacteria increased, Chloroflexi decreased. Therefore, these findings suggest can properties enhance supply.

Cocoa is a vital crop globally, yet its production influenced by various cropping systems that can significantly affect field performance and long‐term sustainability. This study aimed to evaluate how different impact yields, losses from pests diseases, soil fertility, microbial populations in cocoa cultivation. Three distinct were examined within 65‐ha orchard southern Cameroon: monoculture without shade (cropping system 1), grown alongside forest trees Persea americana 2), association with Inga edulis Dacryodes 3). Data collected on metrics, revealed significant differences ( p < 0.05) among the systems. Cropping 2 demonstrated highest across several variables, including number of pods per tree, fresh pod weight, beans pod, both dry bean weights. The yield was also notably higher this system. Conversely, percentage due diseases not three systems, System 1 at 42.18%, 41.21%, 3 43.09%. In terms exhibited superior conditions along more diverse population. dominant bacterial genera identified included Actinomycetes , Azotobacter Bacillus Clostridium Streptomyces while fungal Aspergillus Penicillium Trichoderma . Interestingly, load 1.89 × 10 6 CFU.g −1 whereas had loads 2.09 1.91 respectively.
