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.
Soil-Microbial CNP Content and Ecological Stoichiometry Characteristics of Typical Broad-Leaved Tree Communities in Fanjing Mountain in Spring
This paper is not about microplastics; it examines soil microbial carbon, nitrogen, and phosphorus stoichiometry across four subtropical forest types in Fanjing Mountain, China, to understand nutrient cycling and microbial nutrient limitations.
Effects of tobacco plant residue return on rhizosphere soil microbial community
Researchers found that returning tobacco crop residues to soil significantly increased the diversity and complexity of soil microbial communities, boosting beneficial bacteria like Sphingomonas. This suggests that recycling crop residues is a practical strategy for improving soil health and agricultural ecosystem functioning.
Microplastics affect the ecological stoichiometry of plant, soil and microbes in a greenhouse vegetable system
Researchers added polyethylene microplastics to greenhouse vegetable soil at different concentrations and found significant disruption to the balance of carbon, nitrogen, and phosphorus in the soil, soil microbes, and the plants themselves. Higher concentrations of microplastics altered the soil chemistry and shifted microbial communities, which could affect nutrient cycling and crop health. This matters for human health because microplastic-contaminated agricultural soil may impact the nutritional quality of the food we eat.
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.

Researchers used soil microbial community profiling and metabolomics to investigate how controlled-release fertilizer application rates affect sugarcane growth. The study found that different fertilizer rates significantly influenced root-associated microbial communities and soil metabolite patterns, providing insights into optimizing fertilizer use for improved crop production.
Unearthing soil-plant-microbiota crosstalk: Looking back to move forward
This review examines the complex interactions between soil, plants, and microbiota, tracing the evolution of soil fertility assessment from crop performance metrics to modern microbiome-based approaches. Researchers emphasize that soil quality must be evaluated by combining physical, chemical, and biological parameters, and that understanding microbial community dynamics is essential for sustainable agriculture and ecosystem health.
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.
Synergistic effects of biochar and phosphate fertilizer on fungal communities and soybean productivity in microplastic-contaminated alkaline soils
Researchers investigated synergistic effects of biochar and phosphate fertilizer on fungal communities and phosphorus dynamics in alkaline soils containing microplastics, finding that biochar application could partially counteract the disruption of plant-microbe-soil phosphorus dynamics caused by microplastic contamination.
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.
Research progress on the effects of different fertilizers on soil microorganisms
This review examines how different fertilizer types — chemical, organic, and compound — affect soil microbial communities, summarizing research on how fertilizer-induced changes in microbial diversity and function influence nutrient cycling and crop yield.
Diversity and interactions of rhizobacteria determine multinutrient traits in tomato host plants under nitrogen and water disturbances
Researchers investigated how root-associated bacteria help tomato plants maintain nutrient uptake under nitrogen and water stress conditions. They found that microbial diversity and species interactions were key factors in supporting the plant's ability to acquire multiple nutrients simultaneously. While not directly about microplastics, the study advances understanding of soil microbiome dynamics that are relevant to agricultural systems increasingly affected by plastic contamination.
Moderate Nitrogen Reduction Increases Nitrogen Use Efficiency and Positively Affects Microbial Communities in Agricultural Soils
A field study found that moderate nitrogen reduction did not significantly reduce crop yield due to increased nitrogen use efficiency driven by higher available phosphorus and potassium, while short-term nitrogen changes had limited effects on soil microbial community structure but increased nitrification-related bacterial functions.
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.
The impacts of microplastics on the cycling of carbon and nitrogen in terrestrial soil ecosystems: Progress and prospects
This review examines how microplastics in soil affect the cycling of carbon and nitrogen, two elements essential for plant growth and soil health. Microplastics alter soil microbial communities and enzyme activity in ways that change greenhouse gas emissions and nutrient availability, which could ultimately affect crop production and the food supply.
Biochar-mediated remediation of low-density polyethylene microplastic-polluted soil-plant systems: Role of phosphorus and protist community responses
Researchers found that adding biochar (a charcoal-like soil additive) to soil contaminated with microplastics helped improve plant growth by restoring phosphorus cycling. The microplastics disrupted soil microbe communities, but biochar treatment shifted these communities in beneficial ways. This suggests biochar could be a practical tool for farming in soils contaminated with plastic pollution.
Long-term plastic mulching exacerbates the co-limitation of carbon and phosphorus in farmland by altering physicochemical properties and microbial interactions
Researchers examined how prolonged plastic film mulching over 5 to 15 years affects soil microplastic accumulation, nutrient cycling, and microbial communities in Chinese farmland. The study found that long-term mulching significantly increased microplastic abundance while depleting soil carbon and phosphorus, ultimately worsening nutrient co-limitation and disrupting microbial interactions critical for soil health.
Microplastics Influence Phosphate Adsorption in Volcanic Ash Soil
Researchers found that adding polyethylene microplastics to volcanic ash soil slightly increased the soil's ability to hold phosphorus but also made phosphorus easier to wash away, potentially reducing its availability to plants. This suggests microplastic contamination in farmland soils could quietly alter nutrient cycling in ways that affect crop growth.
