ClearPolymeric Hydrogelsin Agriculture: EnvironmentalPerformance, Sustainability Challenges, and Future Perspectives
This review examines polymeric hydrogels as soil amendments for climate-smart agriculture, finding that these cross-linked water-swelling networks can improve soil moisture retention, reduce irrigation frequency, and enhance fertilizer utilization, while also addressing environmental persistence and degradation challenges.
Superabsorbent Hydrogels in the Agriculture and Reclamation of Degraded Areas
This review examines superabsorbent hydrogels, polymer materials that can absorb hundreds of times their weight in water, and their use in agriculture and land restoration. Researchers found that while these materials can significantly improve soil water retention and crop yields, concerns remain about chemical leaching and potential microplastic generation as they degrade. The study suggests that more research is needed on the long-term environmental safety of synthetic hydrogels in soil.
Significance of biopolymer-based hydrogels and their applications in agriculture: a review in perspective of synthesis and their degree of swelling for water holding
Researchers reviewed the development and agricultural applications of hydrogels made from natural biopolymers, which are biodegradable alternatives to synthetic plastics. These hydrogels can retain large amounts of water and deliver nutrients or active compounds to soil in a controlled way. The study suggests that biopolymer hydrogels could help improve crop yields while reducing the environmental burden of synthetic plastic materials in agriculture.
Smart Hydrogels for Sustainable Agriculture
This article reviews how "smart hydrogels" -- materials that can absorb and slowly release water and nutrients -- could transform agriculture by reducing water waste and excessive chemical use. While not directly about microplastics, these gel-based systems could help reduce the environmental contamination that comes from conventional farming practices. The authors highlight that more research is needed to make these materials practical and affordable for widespread farm use.
Unveiling the potency of polymers and their environmental implications: an agricultural perspective
Researchers reviewed the expanding use of synthetic polymers in agriculture — including water-retaining superabsorbent polymers and slow-release coatings — and found that while they boost crop yields and conserve water, they also contribute to soil microplastic pollution over time. The review calls for more research into biodegradable alternatives to reduce the long-term environmental burden of plastic-based farming inputs.
From Fruit Waste to Hydrogels for Agricultural Applications
Not relevant to microplastics — this study develops biodegradable hydrogels from fruit waste (pectin and starch) to reduce water loss and slow herbicide migration in sandy agricultural soils, without any connection to plastic pollution.
Unravelling the ecological ramifications of biodegradable microplastics in soil environment: A systematic review
Researchers reviewed 85 studies on biodegradable microplastics in soil, finding that when biodegradable plastics fail to fully break down they can disrupt soil structure, nutrient cycling, and microbial life in ways that depend heavily on concentration and plastic type. The review highlights that "biodegradable" plastics are not a simple fix for microplastic pollution in agricultural soils.
Environmental fate and effects of mulch films on agricultural soil: A systematic review from application to residual impact
This systematic review examines how plastic mulch films used in agriculture break down over time and release microplastics into farm soil. The films improve crop growth but create lasting environmental damage as plastic fragments accumulate and alter soil properties. The findings underscore the importance of developing truly biodegradable alternatives to protect farmland from microplastic pollution.
Investigating the sustainability of agricultural plastic products, combined influence of polymer characteristics and environmental conditions on microplastics aging
Researchers investigated how polymer characteristics and environmental conditions influence the photodegradation of agricultural plastic products in soil. The study examined low-density polyethylene microplastic degradation under different UV radiation and humidity conditions. The findings suggest that environmental factors significantly affect how agricultural plastics break down into microplastics, with implications for understanding long-term soil contamination from farming practices.
Microplastics in Agriculture- a Review
This review examines the growing presence of microplastics in agricultural environments, covering their sources from plastic mulch films and irrigation water, their effects on soil health and crop quality, and the implications for food safety and sustainable agriculture.
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.

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.
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.

Microplastics alter soil structural stability as quantified by high-energy moisture characteristics
Scientists found that adding polypropylene and polyethylene microplastic fibers to soil changed its physical structure by altering pore spaces and weakening soil aggregates. Larger fiber sizes and higher concentrations caused more disruption to soil water retention and drainage. These changes to soil structure could affect crop growth and water management on farms where microplastic contamination from irrigation or mulch films has accumulated.
