ClearMicroplastic Contamination in Agricultural Soils: Impacts on soil properties and plant performance
This review synthesized research on microplastic contamination in agricultural soils, examining how MPs affect soil physical properties, chemistry, and plant growth performance. It identified key knowledge gaps around MP accumulation rates, long-term soil effects, and impacts on food crop yields.
Microplastics in Agricultural Soil
This book chapter surveys microplastic contamination in agricultural soils, reviewing the sources of plastic inputs, concentrations found in different farming systems, and the effects of MPs on soil properties, microbial communities, and crop yields.
Effect of microplastics used in agronomic practices on agricultural soil properties and plant functions: Potential contribution to the circular economy of rural areas
Researchers measured the effects of microplastics used in common agricultural practices — including mulch film residues and irrigation-delivered particles — on soil physical, chemical, and biological properties. Microplastic presence altered soil aggregation, water retention, and microbial community composition, with effects depending on plastic concentration, polymer type, and soil texture.
The Growing Problem of Soil Pollution with Microplastics: a Review
This review examined how microplastic accumulation in soil disrupts physicochemical properties including structure, porosity, and water retention, impairs soil microbial communities, inhibits plant growth, and causes oxidative stress, with agricultural soils identified as especially vulnerable to contamination.
Evaluating the impacts of microplastics on agricultural soil physical, chemical properties, and toxic metal availability: An emerging concern for sustainable agriculture
This study tested how five common types of microplastics affect soil properties and heavy metal availability in agricultural soil over 90 days. Microplastics changed soil structure, nutrient levels, and water-holding capacity, and actually reduced the availability of toxic heavy metals at higher plastic concentrations -- highlighting the complex ways plastic pollution is altering the farmland that produces our food.
Assessing Microplastic Contamination Effects on Soil Microbial Communities in Agricultural Land
This study sampled agricultural soils with varying degrees of microplastic contamination to assess effects on microbial diversity, abundance, and enzymatic activity, finding that higher microplastic concentrations reduced microbial diversity and suppressed nutrient-cycling enzyme activity.
Tiny toxins, big problems: the hidden threat of microplastic in agroecosystems
This review examines the impacts of microplastic contamination in agricultural soils, covering sources from plastic mulch and irrigation, effects on soil structure, water retention, microbial diversity, and nutrient cycling, and consequences for crop health and food safety.
Microplastic: Evaluating the Impact on Soil-Microbes and Plant System
This review examines how microplastics affect soil microbial communities and plant systems in agricultural settings, documenting impacts on soil health, microbial diversity, and crop physiology. As microplastics accumulate in farmland soils through irrigation, sludge application, and plastic mulches, their effects on the soil ecosystem that underpins food production are a growing concern.
Effects of microplastic pollution on agricultural soil and crops based on a global meta‐analysis
This meta-analysis examined data from studies worldwide to assess how microplastic pollution affects agricultural soil and crops. Researchers found that microplastics can alter soil properties including enzyme activity and nutrient availability, with effects varying by plastic type, concentration, and size. The study suggests that microplastic contamination in farmland may affect both soil health and crop growth in ways that depend heavily on local conditions.
Effects of microplastics on farmland soils and plants: a review
This review synthesized evidence on how microplastics affect farmland soils and crops, examining changes to soil structure, microbial communities, and plant health. The authors document that MPs can enter root systems, alter nutrient uptake, and disrupt soil ecology, with implications for food safety and agricultural productivity.
Assessment of microplastic pollution on soil health and crop responses: Insights from dose-dependent pot experiments
Researchers combined field investigation and pot experiments to assess how microplastic contamination at different doses affects soil health indicators and crop growth performance. Field soils showed measurable microplastic contamination, and pot experiments demonstrated dose-dependent effects on soil enzyme activity, water retention, and plant growth metrics.
Plastics in soils: impacts on agriculture and food
This work reviews the impacts of plastic pollution in soils on agricultural productivity and food safety, examining how plastic particles and associated chemicals affect soil health, crop growth, and food quality. The publication is part of the international scientific literature on plastic contamination of agricultural systems.
Microplastics Can Change Soil Properties and Affect Plant Performance
Researchers tested six different types of microplastics in soil and found that they altered key soil properties including water-holding capacity, bulk density, and microbial activity. These changes in soil structure had cascading effects on plant growth, with some microplastic types reducing above-ground biomass. The study demonstrates that microplastics can fundamentally change how soil functions, with consequences for plant health and ecosystem stability.
Impact of Microplastics on Soil Health: Soil-Water Retention, Shrinkage and Holding Properties
A review of research on microplastics in soil found that plastic particles can alter water retention, shrinkage, and structural properties in ways that could reduce agricultural productivity. Because microplastics are as prevalent in soils as in oceans, their terrestrial impacts warrant much greater research attention.
Microplastics accumulation in agricultural soil: Evidence for the presence, potential effects, extraction, and current bioremediation approaches
This review examines the accumulation of microplastics in agricultural soils from sources like plastic mulching and irrigation, discussing their effects on soil properties and crop growth, along with current bioremediation approaches for removing soil microplastics.
Integrated effects of residual plastic films on soil-rhizosphere microbe-plant ecosystem.
This pot experiment investigated how residual plastic film fragments of different sizes in agricultural soil affect soil properties, microbial enzyme activity, nutrient levels, and plant growth. Larger plastic residues caused greater disruption to soil health and reduced crop yield, suggesting that accumulated mulch film pollution poses a serious threat to long-term agricultural productivity.
Macro- and micro-plastics change soil physical properties: a systematic review
This systematic review examines how plastic particles — both large and microscopic — change important soil properties like water retention, density, and structure. These changes can affect how well soil supports plant growth and produces food, raising concerns about the long-term impact of plastic pollution on agriculture.
[Adverse Effects and Underlying Mechanisms of Soil Microplastics on Crops and Its Preventive Strategies].
This review summarizes the pollution status of microplastics in agricultural soils and their adverse effects on crops, including mechanical damage, oxidative stress, and genotoxicity leading to disrupted plant growth and metabolism. Researchers also examined how hazardous substances released from microplastics and contaminants adsorbed onto their surfaces contribute to soil ecosystem harm. The study identifies source control and biodegradation as the most promising strategies for reducing microplastic risks to crop production.
