ClearManagement affects the diversity and functions of root and leaf-associated microbiomes: implications for olive resilience
Researchers studied how different farming practices, including organic, conventional, and traditional methods, shape the microbial communities associated with olive tree roots and leaves. They found that agricultural management significantly influenced microbiome diversity and functional traits, with organic practices generally supporting more beneficial microbe populations. The findings suggest that farming methods play an important role in the overall health and resilience of olive trees.
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.
Functional profile of the microbiome in the rhizosphere of drought- tolerant beans
Researchers investigated the functional microbiome profiles of the rhizosphere of drought-tolerant and drought-susceptible common bean (Phaseolus vulgaris) cultivars under different water stress conditions using mesocosm experiments, finding distinct microbial functional signatures associated with drought tolerance. The study provides insights into how soil microorganisms contribute to crop resilience, with implications for sustainable agricultural practices that reduce the need for plastic-intensive irrigation infrastructure.
Organic fertilizer mitigated the oxidative stress of tomato induced by nanoplastics through affecting rhizosphere soil microorganisms and bacteriophage functions
Researchers investigated whether organic fertilizer could protect tomato plants from the harmful effects of nanoplastics in soil. They found that organic fertilizer reduced oxidative stress in tomato stems by roughly 25-35% compared to chemical fertilizer, primarily by boosting beneficial soil bacteria and bacteriophage activity in the root zone. The study suggests that organic farming practices may help buffer crops against nanoplastic contamination in agricultural soils.
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.
Application of Organic Fertilizer Changes the Rhizosphere Microbial Communities of a Gramineous Grass on Qinghai–Tibet Plateau
Researchers examined how organic fertilizer application altered rhizosphere microbial communities in a gramineous grass, finding significant shifts in bacterial diversity and composition that may influence nutrient cycling and soil health in grassland ecosystems.
Agroecological transition: towards a better understanding of the impact of ecology-based farming practices on soil microbial ecotoxicology
This review examined how ecology-based farming practices like organic farming, agroecology, and permaculture affect soil microorganisms compared to conventional agriculture. The study suggests that these alternative approaches generally support healthier soil microbial communities, though more research is needed to fully understand how reduced pesticide and chemical use benefits the complex web of organisms that drive soil fertility.
How Organic Mulching Influences the Soil Bacterial Community Structure and Function in Urban Forests
Researchers tested how different types of organic mulch affect the bacterial communities in urban forest soils. They found that wood chips and compost changed the soil's chemical properties and shifted the types of bacteria present, particularly those involved in carbon and nitrogen cycling. The study suggests that organic mulching could be a practical tool for improving the microbial health of urban soils.
Shifts in maize microbial communities and networks are correlated with the soil soil chemical property under different fertilization regimes
A corn field experiment compared how different fertilizers — chemical versus organic — shaped soil microbial communities and their interaction networks. Organic fertilizers altered both the diversity and connections between soil microbes, which has implications for soil health and agricultural sustainability.
The Importance of Humic Acids in Shaping the Resistance of Soil Microorganisms and the Tolerance of Zea mays to Excess Cadmium in Soil
Researchers assessed whether a humic acid soil amendment (Humus Active) could protect maize from cadmium toxicity by modifying the soil bacterial community structure under heavy metal stress. Humic acid treatment improved soil bacterial diversity and reduced cadmium uptake by maize, suggesting that humic preparations can partially restore soil microbiome function and crop health in cadmium-contaminated agricultural land.
Influence of Biochar on Soil Nutrients and Associated Rhizobacterial Communities of Mountainous Apple Trees in Northern Loess Plateau China
Researchers found that biochar application at varying rates improved soil nutrient availability and significantly altered rhizobacterial community structure in mountainous apple orchards, with moderate application rates showing the greatest benefits for soil health.
Influence of different irrigation methods on the alfalfa rhizosphere soil fungal communities in an arid region
Researchers examined how traditional flood irrigation versus drip irrigation methods affect fungal diversity, community structures, and ecological functions in alfalfa rhizosphere soils in the arid Xinjiang region of China, finding that irrigation method significantly shapes soil fungal communities.
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.
Plant Disease Management: Leveraging on the Plant-Microbe-Soil Interface in the Biorational Use of Organic Amendments
This review discusses how organic soil amendments can help restore soil health and manage plant diseases by supporting beneficial microbial communities in the root zone. Researchers found that organic amendments improve the interactions between plants, soil microbes, and the surrounding soil environment, creating conditions less favorable for plant pathogens. The study emphasizes that sustainable agricultural practices that nurture soil biology may reduce the need for synthetic pesticides and plastics in farming.
Physio-Biochemical Mechanisms of Arbuscular Mycorrhizal Fungi Enhancing Plant Resistance to Abiotic Stress
This review explores how arbuscular mycorrhizal fungi, beneficial soil organisms that form partnerships with plant roots, help crops cope with environmental stresses like drought, salinity, and heavy metal contamination. The fungi improve nutrient uptake, water absorption, and antioxidant defenses while triggering beneficial hormonal responses in host plants. The authors note that wider agricultural use of these fungi is limited by challenges in mass production and variability across different crops and soil conditions.
