ClearParameters of labile organic carbon as the indicators of the stability of soil organic matter under different land use
Despite its title referencing soil organic carbon and land use, this paper studies chemical indicators of soil organic matter stability under different farming practices — not microplastic pollution. It examines which carbon fractions best signal how organic matter is protected in forest and agricultural soils, and is not relevant to microplastics or human health.
A 10-Year Monitoring of Soil Properties Dynamics and Soil Fertility Evaluation in Chinese Hickory Plantation Regions of Southeastern China
A 10-year soil monitoring study in Chinese hickory plantations found that intensive agricultural management caused significant changes in soil chemistry and fertility over time. While not directly about microplastics, understanding soil health in managed agricultural landscapes is relevant to assessing microplastic accumulation in farmland soils.
Stability of organic carbon pools and sequestration potential as affected under different agroforestry systems
This study evaluates how five different agroforestry systems affect soil organic carbon stability and sequestration in degraded Himalayan soils in northeast India. It is not about microplastics and is a false positive for microplastic relevance.
Assessment of Soil Microplastics and Their Relation to Soil and Terrain Attributes Under Different Land Uses
Researchers assessed microplastic contamination in tropical soils under different land uses including forest, grassland, and agricultural areas. They found that agricultural soils had the highest microplastic concentrations, likely due to the use of plastic-based materials in farming. The study reveals how land use practices and soil characteristics influence the distribution and accumulation of microplastics in tropical environments.
A comprehensive review of impacts of soil management practices and climate adaptation strategies on soil thermal conductivity in agricultural soils
This review examines how farming practices like tillage, crop rotation, and mulching affect how well soil conducts heat, which influences crop growth and water availability. While not directly about microplastics, the paper highlights that disrupted soil structure from various agricultural inputs can alter important soil properties, which is relevant as microplastic contamination of farmland soils continues to grow.
Mechanism of polyethylene and biodegradable microplastic aging effects on soil organic carbon fractions in different land-use types
Researchers compared how polyethylene and biodegradable microplastics at different stages of aging affect soil organic carbon fractions across various land-use types. The study found that both types of microplastics altered soil carbon dynamics, but the effects depended on the plastic type, its degree of aging, and the specific land-use context.
Microplastic Contamination and Its Impact on Soil Properties Across Different Land Uses in Cross River State, Nigeria
A survey of soils across four land-use types in southeastern Nigeria found microplastic concentrations up to 12 times higher in commercial areas than in forests, with contamination linked to changes in soil structure, nutrient availability, and water infiltration. This is the first large-scale assessment of microplastic distribution in Nigerian tropical soils, filling a major data gap for sub-Saharan Africa. The findings suggest that heavily contaminated commercial soils may have degraded agricultural and ecological functionality, with consequences for food security in the region.
Influences of land use and depth profile on the characteristics of microplastics in agricultural soils
Researchers examined how land use and soil depth profile influence microplastic characteristics in agricultural soils, finding that wastewater and sludge application, plastic mulching, and atmospheric deposition are key sources, and that MP type and abundance vary with soil management practice and depth, highlighting the importance of vertical distribution in soil MP studies.
Microplastics influence organic carbon depletion in macroaggregates and soil structural stability in the Yanhe catchment
Researchers investigated how microplastics within soil aggregate fractions affect organic carbon retention and structural stability in the Yanhe catchment, finding that microplastics accelerate organic carbon depletion from macroaggregates and reduce soil structural stability. The results suggest that microplastic contamination in agricultural soils may compound land-use-driven degradation of soil quality.
Differential carbon accumulation of microbial necromass and plant lignin by pollution of polyethylene and polylactic acid microplastics in soil
This study found that both conventional polyethylene and biodegradable polylactic acid microplastics changed how carbon is stored in soil. The plastics increased carbon from dead microbes while decreasing carbon from plant material, with most of the additional soil carbon coming from fungal remains. These changes to soil chemistry matter because they could affect agricultural productivity and the ability of soil to store carbon, with broader implications for climate and food systems.
Specific response of soil properties to microplastics pollution: A review
This review summarizes how microplastic pollution changes the physical, chemical, and biological properties of soil. Microplastics can alter soil structure, water retention, and nutrient cycling, and they also affect the communities of microorganisms that keep soil healthy. Since contaminated soil grows our food, these changes could indirectly affect human health through the food supply.
Research on Soil Management and Conservation
Not relevant to microplastics — this is a brief editorial introduction to a journal special issue on soil management and conservation, with no substantive content about microplastic pollution.
Silent Alienation of Soils through Microplastic in the Anthropocene – A Constraint for Soil Productivity?
This review examines how microplastics accumulate in soils and alter their physical properties and biological communities over time. Microplastics resist biodegradation and can reduce soil porosity, alter water retention, and harm soil organisms. The authors argue that ongoing plastic accumulation in farmland poses a long-term threat to soil productivity and global food security.
Microplastics in agricultural soils : effects on physical, chemical, and microbiological processes
This thesis examines how pristine and degraded conventional microplastics (polyethylene and PET) and biodegradable microplastics (PBAT) affect soil physical, chemical, and microbial properties across silty loam and sandy loam soils, integrating five studies involving greenhouse and laboratory experiments to assess impacts on aggregation, water-holding capacity, carbon storage, respiration, nutrient cycling, and microbial community composition.
Microplastic diversity, risks and soil impacts: A multi-metric assessment across land-use systems
Researchers surveyed microplastic abundance, polymer diversity, and ecological risk across seven land-use types in India's Brahmaputra Valley, finding that built-up areas had the highest particle counts while forest soils paradoxically showed the greatest polymer hazard scores due to high-risk polymers, and that land-use type shapes both the quantity and composition of soil microplastic contamination.
Effects of microplastics on soil physical, chemical and biological properties
This review examines how microplastics affect soil health, covering their impact on the physical structure, chemical composition, and biological communities of soil ecosystems. Microplastics can alter soil water retention, change nutrient cycling, and harm soil organisms from earthworms to microbes. Since agricultural soils are a major reservoir of microplastics, these changes could affect crop growth and food quality, creating an indirect pathway for microplastic-related harm to human health.
Can microplastics mediate soil properties, plant growth and carbon/nitrogen turnover in the terrestrial ecosystem?
This review assessed evidence for microplastic effects on soil properties, plant growth, and carbon and nitrogen cycling in terrestrial ecosystems. Microplastics were found to alter soil structure, water retention, microbial activity, and nutrient cycling, with cascading effects on plant growth and soil organic matter turnover.
Examining Soil Microplastics: Prevalence and Consequences Across Varied Land Use Contexts
Scientists examined microplastic contamination in soil samples from different land use areas in Makassar City, Indonesia. They found microplastics present across all sites, with the types and concentrations varying based on how the land was used, whether for agriculture, residential, or commercial purposes. The study suggests that human activity patterns strongly influence the amount and kind of microplastic pollution found in urban and agricultural soils.
Changes in Soil Properties Under the Influence of Microplastics in Plastic and Open Field Production in Three Serbian Valleys
Researchers examined soil physical, chemical, and biological properties in greenhouse and open-field soils across three Serbian valleys to test whether mulch film use leads to microplastic accumulation and soil alteration. Greenhouse soils showed elevated MP concentrations that correlated with changes in chemical and biological parameters, supporting the hypothesis that repeated plastic mulch use degrades soil quality.
