ClearCulturomics and Amplicon-Based Metagenomic Insights into the Bacteria of Soils with High Yield of Oryza sativa L. subsp. Japonica
Researchers used culturomics and amplicon-based metagenomics to characterise bacterial communities in rhizosphere and bulk soils of high-yield Oryza sativa japonica paddy fields, identifying the microorganisms contributing to rice growth adaptability. The combined approach revealed the taxonomic composition and functional potential of the bacterial community in the paddy field agroecosystem.
Short‐term effects of mineral and combined mineral‐organic fertilization in soil microbial communities
A one-year fertilization trial in a Qinghai-Tibet Plateau greenhouse found that both mineral and combined mineral-organic fertilization increased bacterial richness and decreased fungal diversity compared to unfertilized soil, with available phosphorus as the primary driver of microbial community structure changes.
Addition of High-Quality Plant Residue Alters Microbial Keystone Taxa and Network Complexity and Increases Soil Phosphorus (P) Availability
Researchers found that adding high-quality plant residues like pumpkin stems to acidic soil boosted available phosphorus by nearly 64 percent and stimulated beneficial microbial communities. The improvement was linked to increased populations of key bacterial species and stronger cooperative interactions among soil microbes. The study suggests that the type and quality of plant material added to soil plays a critical role in shaping microbial networks that drive nutrient cycling.
Phosphorus fertiliser application mitigates the negative effects of microplastic on soil microbes and rice growth
Researchers found that adding phosphorus fertilizer to soil contaminated with microplastics helped counteract the negative effects of the plastics on rice growth and soil microbial communities. The microplastics alone disrupted bacterial interactions and suppressed plant development, but fertilizer application restored much of the lost productivity. The study offers practical guidance for managing agricultural soils in areas affected by microplastic pollution.
The application of biochar and organic fertilizer substitution regulates the diversities of habitat specialist bacterial communities within soil aggregates in proso millet farmland
Researchers conducted a field experiment on millet farmland to study how biochar and organic fertilizer combinations affect soil bacterial communities, finding that combining both improved soil nutrients and bacterial diversity more than either treatment alone — supporting healthier, more resilient farming soils.
A Comparison of Rice Root Microbial Dynamics in Organic and Conventional Paddy Fields
Researchers compared the root-associated microbial communities of rice plants grown in organic versus conventional paddy fields across different growth stages. They found that organic farming supported more dynamic and diverse microbial communities, including beneficial methane-oxidizing and nitrogen-fixing bacteria at key growth stages. The study suggests that agricultural management practices significantly shape the microbial partners that support rice plant health and nutrient uptake throughout the growing season.
Maize root-soil microbial interactions and their effects on soil health and yield
Researchers examined interactions between maize roots and soil microbial communities, investigating how root-microbe dynamics influence soil health indicators and crop yield. The study found specific rhizosphere microbial associations that promote nutrient availability and plant productivity.
Inter-phylum negative interactions affect soil bacterial community dynamics and functions during soybean development under long-term nitrogen fertilization
Researchers found that the growth stage of soybean plants had a stronger influence on soil bacterial communities than 16 years of nitrogen fertilization, while fertilization more strongly shaped nitrogen-processing gene activity. Negative interactions between certain bacterial groups helped explain how soil microbial communities change over a crop's growing season.
Effects of the Long-Term Continuous Cropping of Yongfeng Yam on the Bacterial Community and Function in the Rhizospheric Soil
Researchers investigated how long-term continuous cropping of yam over 1 to 20 years affects rhizospheric soil bacterial communities and soil properties. The study found that prolonged monoculture caused soil acidification and shifted bacterial community composition, with decreased diversity in most cases, though fields under 20 years of cultivation showed a recovery in bacterial diversity.
In-Depth Insights into the Complex Interplay Between Microbial Diversity, Ecological Functionality, and Soil Health in Rice Agroecosystems
This review paper summarizes existing research on tiny organisms (microbes) that live in rice paddies and how they affect the rice we eat. Scientists found that these microbes play important roles in rice farming - they help break down plant waste, control harmful gases like methane, and can influence whether rice contains dangerous toxins or beneficial nutrients. The research suggests that farmers could manage these microbes better to grow healthier rice while protecting the environment, but more studies are needed to make this practical.
Impact of Combined Exposure to Glyphosate and Diquat on Microbial Community Structure and Diversity in Lateritic Paddy Soil
Combined exposure to glyphosate and diquat herbicides in lateritic paddy soil primarily affected Actinobacteria and Proteobacteria, with the combination increasing Actinobacteria abundance while significantly suppressing Proteobacteria, particularly at low and medium concentrations.
Effect of Polyvinyl Chloride Microplastics on Bacterial Community and Nutrient Status in Two Agricultural Soils
Polyvinyl chloride microplastics at environmentally relevant concentrations did not broadly alter bacterial diversity in two agricultural soils over 35 days, but did significantly change available phosphorus levels and shifted the abundance of specific bacterial genera. The results suggest that microplastic pollution can subtly reshape nutrient cycling and microbial community composition in farmland soils.
Effects of microbial cultures on bacterial communities in the roots of Phyllostachys edulis
Researchers investigated the effects of applying endophytic bacterial cultures isolated from Phyllostachys edulis on bacterial communities in bamboo root systems and rhizosphere, as well as on soil chemical properties. Seven root samples were collected from experimental plots treated with a mixed culture of four bacteria, revealing how microbial inoculants reshape root-associated microbial communities.
A Review on Soil and Phytomicrobiome for Plant Disease Management
This review examines how soil microbiomes and agricultural practices influence plant disease management, highlighting the role of beneficial microorganisms in suppressing pathogens. Researchers found that conservation tillage, crop rotation, and mulching promote microbial diversity that helps protect crops from soil-borne diseases. The study suggests that integrating microbiome-focused strategies into farming could reduce reliance on chemical pesticides while improving crop health.
Effects of Priestia aryabhattai on Phosphorus Fraction and Implications for Ecoremediating Cd-Contaminated Farmland with Plant–Microbe Technology
Researchers found that a soil bacterium called Priestia aryabhattai, trained to tolerate cadmium contamination, can help convert unavailable phosphorus in soil into forms that plants can use. The study suggests this microbe could be a useful tool for restoring farmland contaminated with heavy metals while simultaneously improving soil fertility.
Divergent mechanisms of labile phosphorus accumulation in paddy soils under TPU microplastics versus manure-derived hydrochar: roles of dissolved organic matter and bacterial communities
Scientists found that tiny plastic particles and a charcoal-like material called hydrochar can increase the amount of phosphorus available to rice plants in soil by 14-21%. Both materials work by changing the soil's chemistry and the helpful bacteria that live in it, but they do it in different ways. This matters because phosphorus is essential for growing healthy crops, and understanding how plastic pollution affects soil could help farmers maintain productive rice fields.
Identification of culturable bacteria associated with the rhizosphere of Lablab purpureus growing in Namibia
Culturable bacteria associated with the rhizosphere of Lablab purpureus, a drought-tolerant protein-rich legume crop, were identified in Namibia to support agricultural productivity in marginalised areas.
