ClearHow Do Mixed Cover Crops (White Mustard + Oats) Contribute to Labile Carbon Pools in an Organic Cropping System in Serbia?
Researchers studied how a mixed cover crop of white mustard and oats affected soil carbon pools in an organic farming system in Serbia. They found that the cover crop mixture contributed to increased microbial carbon and nitrogen in the soil, supporting overall soil health. The study suggests that cover cropping strategies can help sequester carbon and maintain fertility in organic agricultural systems.

Researchers found that microplastics in soil can increase nutrient uptake by wheat by stimulating microbial activity and altering root interactions, suggesting microplastics may disrupt natural nutrient-cycling strategies in agricultural systems.
[Effects of Polyethylene Microplastics with Different Particle Sizes on Soil Organic Carbon Characteristics and Mineralization in Agricultural Soil].
Researchers conducted a 180-day indoor soil cultivation experiment to investigate how polyethylene microplastics of different particle sizes — millimeter-scale, micrometer-scale — affect soil organic carbon characteristics and mineralization processes in agricultural soil.
The potential contribution of nanocarbon to fostering sustainable agriculture for future generations
This paper is not about microplastics — it reviews how nanocarbon materials can be applied in agriculture to improve soil structure, enable controlled nutrient release, purify water, and monitor crop health, while noting safety concerns around their broader adoption.
Microplastics Can Inhibit Organic Carbon Mineralization by Influencing Soil Aggregate Distribution and Microbial Community Structure in Cultivated Soil: Evidence from a One-Year Pot Experiment
Researchers conducted a one-year pot experiment to study how different types and concentrations of microplastics affect soil carbon cycling and aggregate stability. They found that microplastics significantly altered soil aggregate size distribution and decreased organic carbon mineralization rates regardless of polymer type. The study suggests that microplastic contamination may slow the natural breakdown of organic carbon in agricultural soils by changing soil structure and microbial communities.
Enzymatic-Driven Responses of Soil Fertility and Crop Yields to Different Long-Term Organic Substitution Regimes Under Wheat–Maize Rotation
Scientists found that replacing some chemical fertilizers with organic materials like chicken manure and crop waste can maintain crop yields while making soil much healthier. The organic materials boost helpful soil enzymes that break down nutrients, creating richer soil with more carbon and nitrogen that plants can use. This approach could help farmers grow food more sustainably while reducing their dependence on chemical fertilizers, which is important for long-term food security and environmental health.
A Double‐Edged Sword of Biodegradable Microplastics on the Soil Microbial Carbon Pump
Researchers found that biodegradable microplastics in soil had a double-edged effect: they increased carbon dioxide emissions (contributing to greenhouse gases) but also boosted the efficiency of soil microbes at storing carbon in stable forms. This suggests microplastic pollution in farmland has complex environmental consequences that go beyond simple contamination, potentially affecting both climate change and long-term soil health.
Microplastic-Induced Alterations in Soil Aggregate-Associated Carbon Stabilization Pathways: Evidence from δ13C Signature Analysis
Researchers conducted a year-long field experiment to understand how different types of microplastics affect carbon storage in soil. They found that conventional plastics like polyethylene and PVC destabilized soil structures and released stored carbon, while biodegradable plastics like PLA and PHA helped maintain soil integrity. The study provides evidence that the type of plastic contaminating agricultural soils significantly influences whether carbon is retained or lost.
A biobased, bioactive, low CO2impact coating for soil improvers
Researchers developed a bio-based, low-carbon coating system made from natural materials for use in lawn and soil management applications. Eco-friendly coatings that replace synthetic polymer coatings could reduce the microplastic particles shed by conventional plastic-coated slow-release products.
Contributions of fine mineral particles and active Al/Fe to stabilization of plant material in neutral-to-alkaline soils of Indo-Gangetic Plain
Researchers studied how organic carbon added to farmland soils in northern India gets stored or broken down, finding that clay particles and aluminum and iron compounds are key to locking carbon in place for the long term. Understanding these mechanisms is important for predicting how tropical agricultural soils can help offset carbon emissions through carbon sequestration.
Enhancing carbon restoration and ecosystem resilience in global drylands via water-to-carbon biotransformation strategies
Researchers synthesized thousands of experiments on dryland farming and found that combining crop diversification, efficient irrigation, soil mulching, and soil health practices can significantly restore carbon to depleted soils while improving water use efficiency. The study argues these strategies are practical pathways for combating climate change and food insecurity in the world's most water-stressed regions.
Analysis of Slow-Released Fertilisers as a Source of Microplastics
Analysis of slow-release fertilisers coated with polymer shells found that these products can release microplastics into agricultural soils as the coatings degrade. Two major manufacturers' products showed varying polymer compositions and differing abilities to adsorb soil contaminants, raising concerns about MP accumulation from fertiliser use.
Organic Mulching to Conserve Soil Nutritional Quality and Enhance Wheat Yield
Organic mulching with farm manure and wheat straw preserved soil nitrogen, phosphorus, and potassium levels while significantly increasing wheat grain and straw yields. Combining both mulch types at higher rates was most effective, offering a practical strategy to maintain soil nutritional quality under intensive farming.
Microplastic Disguising As Soil Carbon Storage
This study investigated whether microplastics in soil are mistakenly counted as carbon storage, finding that microplastic particles can interfere with soil carbon measurements and may cause overestimates of organic carbon in agricultural and natural soils.
Uncovering the intricate relationship between plant nutrients and microplastics in agroecosystems
A study of wheat grown in soils with varying microplastic levels found complex interactions between MPs and plant macronutrients and micronutrients, with MPs altering nutrient uptake in ways that could affect crop productivity in contaminated agricultural soils.

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.
Microplastics Generate Less Mineral Protection of Soil Carbon and More CO2 Emissions
Researchers investigated how dissolved organic matter released from microplastics affects soil carbon storage compared to natural organic matter. They found that microplastic-derived compounds are nearly eight times more easily consumed by soil microbes, leading to significantly higher carbon dioxide emissions and much less carbon being stored in soil minerals. The findings suggest that microplastic pollution in agricultural and natural soils may undermine the land's ability to store carbon and contribute to climate warming.
Quantification and identification of microplastics in organic fertilizers: the implication for the manufacture and safe application
Researchers measured microplastic contamination in 23 commercial organic fertilizers, finding widespread presence at levels that could meaningfully contribute to agricultural soil pollution when fertilizers are applied.

Differential impacts of microplastics on carbon and nitrogen cycling in plant-soil systems: A meta-analysis
A meta-analysis of 3,338 observations found that microplastics increased soil CO2 emissions by 25.7% but also boosted soil carbon storage through increases in total carbon (53.3%), soil organic carbon (25.4%), and microbial biomass carbon (19.6%). However, microplastics decreased plant aboveground biomass and reduced nitrate and ammonia volatilization, suggesting that while soil carbon sink capacity may increase, agricultural productivity could suffer.
