ClearThe impact of different preceding crops on soil nitrogen structure and nitrogen cycling in tobacco-planting soil
Researchers examined how the crop grown in a field before tobacco affects soil nitrogen levels and the microbial genes responsible for nitrogen cycling, finding that barley and rapeseed as preceding crops significantly increased available nitrogen while suppressing key nitrification genes. The results suggest crop rotation can meaningfully shape soil nutrient dynamics and microbial communities, with implications for sustainable tobacco farming.
Interactions between Sugarcane Leaf Return and Fertilizer Reduction in Soil Bacterial Network in Southern China Red Soil
This study examined how combinations of sugarcane leaf return and fertilizer reduction affect soil bacterial communities, finding that residue management significantly shapes microbial diversity and functional guilds involved in nutrient cycling.
Microbial fertilizer regulates C:N:P stoichiometry and alleviates phosphorus limitation in flue-cured tobacco planting soil
Researchers studied how adding microbial fertilizer to tobacco farmland affects the balance of carbon, nitrogen, and phosphorus in the soil, finding that phosphorus availability becomes the main limiting factor as the growing season progresses. Adding microbial fertilizer helped relieve this phosphorus limitation by shifting soil chemistry, offering a more sustainable approach to crop nutrition management.
Comparison of the response of microbial communities to region and rootstock disease differences in tobacco soils of southwestern China
This study compared microbial communities in tobacco-growing soils across different regions of southwestern China to understand how regional differences and rootstock diseases affect soil microbiomes. The findings provide insight into the interactions between microbial communities, geographic variation, and plant disease occurrence. The results have implications for maintaining soil health and improving tobacco crop yield and quality.
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.
Impact of cigarette butts on bacterial community structure in soil
Researchers added cigarette butt leachate to soil and found that biodegradable butts significantly altered bacterial community composition compared to non-biodegradable ones, driven by higher concentrations of leached metals like aluminum, iron, and zinc — highlighting cigarette filters as a source of both microplastics and heavy metal soil contamination.
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.
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.
Long-Term Compost Amendment Changes Interactions and Specialization in the Soil Bacterial Community, Increasing the Presence of Beneficial N-Cycling Genes in the Soil
Researchers found that long-term compost amendment significantly altered soil bacterial community structure and functional specialization, increasing microbial network complexity and promoting functional guilds associated with organic matter decomposition compared to non-amended soils.
Effects of biochar amendment on bacterial communities and their function predictions in a microplastic-contaminated Capsicum annuum L. soil
Researchers investigated how adding biochar to soil contaminated with microplastics affects bacterial communities during pepper plant growth. They found that biochar amendment helped restore bacterial diversity and shifted community composition toward beneficial species, counteracting some of the negative effects of microplastic contamination. The study suggests that biochar could be a practical soil management tool for supporting microbial health in plastic-polluted agricultural systems.
Root carbon inputs outweigh litter in shaping grassland soil microbiomes and ecosystem multifunctionality
Researchers analyzed 13 years of field data from a semi-arid grassland and found that carbon inputs from plant roots matter more than leaf litter in sustaining soil microbial diversity and overall ecosystem health. Removing plants caused greater microbial and functional declines than removing surface litter, underscoring the hidden importance of below-ground carbon in maintaining healthy soils.
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.
Microbial responses towards biochar application in potentially toxic element (PTE) contaminated soil: a critical review on effects and potential mechanisms
Researchers reviewed how biochar — a charcoal-like material made from organic waste — can protect soil microorganisms from toxic heavy metal contamination by reducing metal availability and improving soil conditions. The review found that biochar addition consistently shifted microbial communities toward healthier, more diverse compositions, offering a practical soil remediation strategy aligned with sustainability goals.
Integrated microbiology and metabolomics analysis reveal plastic mulch film residue affects soil microorganisms and their metabolic functions
Researchers used high-throughput gene sequencing combined with metabolomics to study how plastic mulch film residues affect soil microorganisms and their metabolic functions. They found that mulch film residues significantly altered microbial community composition and disrupted key metabolic pathways in the soil. The study reveals that plastic agricultural film left in soil can interfere with the biological processes that keep soil ecosystems healthy.
Effects of polyethylene microplastics on the microbial community structure of maize rhizosphere soil
Researchers investigated how polyethylene microplastics from agricultural films affect the microbial communities in crop root zones (rhizosphere), finding shifts in bacterial diversity and function. Disrupting soil microbiomes through microplastic contamination could have downstream effects on soil fertility and crop health.
Biochar contributes to resistance against root rot disease by stimulating soil polyphenol oxidase
Researchers found that adding biochar (a charcoal-like soil amendment made from burning organic matter) to continuously cropped tobacco fields boosted a soil enzyme called polyphenol oxidase, which suppressed fungal root-rot pathogens — demonstrating that biochar can reduce plant disease by improving soil chemistry.
