Relationships between soil salinity and economic dynamics: Main highlights from literature
This bibliometric review of soil salinity research found that most studies focus on agricultural strategies for managing salinity, food security, desertification, and climate change impacts, while direct assessments of socioeconomic impacts from soil salinity and broader sustainability dimensions have received comparatively little attention.
Interactive Effects of Microbial Fertilizer and Soil Salinity on the Hydraulic Properties of Salt-Affected Soil
Researchers studied how adding microbial fertilizer to salt-affected soils changes the soil's ability to absorb and move water.

Microplastics Disrupt Soil Aggregate Stability and Associated Nutrient Dynamics in Mulched Salt-Affected Agricultural Soils
Researchers investigated how microplastic accumulation affects soil aggregate stability and nutrient dynamics in salt-affected agricultural soils in northeastern China. They found that high microplastic abundance significantly disrupted soil structure, reducing large aggregates and creating nutrient imbalances, with the elevated salinity and low organic matter of these soils amplifying the damage. The study highlights the need for targeted strategies to mitigate microplastic contamination in salt-affected farmland where plastic mulch is heavily used.

This review summarized management strategies for salt-affected soils under arid and semi-arid climates, covering approaches to address salinity and alkalinity stress that reduce crop productivity worldwide.
Review of Crop Response to Soil Salinity Stress: Possible Approaches from Leaching to Nano-Management
This review covers approaches to managing soil salinity, a problem that threatens global food production, using methods ranging from traditional leaching to newer nanotechnology-based solutions. While not directly about microplastics, soil health is connected to microplastic contamination because plastic mulch films used in agriculture are a major source of microplastic pollution in farmland soils.
Effects of Microbial Fertilizer Application on Soil Ecology in Saline–Alkali Fields
A two-year study found that microbial fertilizer applications improved soil microecology and reduced salinity in saline-alkali fields, promoting sustainable agricultural development. The results indicated that microbial fertilizers are a viable environment-friendly tool for remediating degraded soils with reduced reliance on synthetic chemical inputs.
Sewage sludge application enhances soil properties and rice growth in a salt-affected mudflat soil
Researchers tested whether adding sewage sludge (a byproduct of wastewater treatment, rich in organic carbon) to salty, degraded coastal soils could improve fertility and rice growth, finding that even at high doses the added organic matter offset the increased salinity and boosted yields. The study suggests sewage sludge amendment is a viable low-cost strategy for reclaiming salt-damaged agricultural land.
Microplastics influence nutrient content and quality of salt-affected agricultural soil under plastic mulch
Microplastics were found in salt-affected agricultural soils in northeast China at abundances ranging across mulched and unmulched fields, with MPs affecting soil nutrient content and quality in ways that could influence food production in this important agricultural region.

Researchers investigated the causes of increasing groundwater salinization in Qinzhou Bay, China, collecting 110 water samples to trace hydrochemical signatures and identify the mechanisms driving saltwater intrusion since 2013. The findings aim to support better water resource management in the affected coastal agricultural region.
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.
Soil water, salt, and microplastics interact during migration: Performance and mechanism
Researchers studied how microplastics and salt interact as they move through farmland soil, finding that salty conditions slow both water flow and microplastic migration, while microplastics in turn hinder the leaching of harmful salts like sodium from the soil. These complex interactions are important for understanding how contaminated agricultural soils behave and how to manage them.

Analysis of the Interaction between Lake and Groundwater Based on Water–Salt Balance Method and Stable Isotopic Characteristics
Researchers analyzed the interaction between Wuliangsu Lake and surrounding groundwater in the Yellow River basin using water-salt balance methods and stable isotopic characteristics, examining how irrigation drainage from the Hetao Irrigation District influences lake water chemistry and ecology. The study found that discharge from agricultural irrigation significantly altered the water-salt dynamics of the lake, contributing to salinization and affecting the lacustrine ecosystem.
High salinity restrains microplastic transport and increases the risk of pollution in coastal wetlands
Researchers investigated how salinity levels affect the transport of microplastics through coastal wetland soils using column experiments. They found that higher salinity significantly reduced microplastic mobility by altering soil pore structure and chemical properties, with transport decreasing substantially as salinity increased. The study suggests that while high salinity traps microplastics near the surface, this retention may concentrate pollution and increase ecological risks in coastal wetland environments.
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.

Insights into simultaneous changes of water evaporation and desiccation crack formation for microplastics-contained saline soils
Researchers examined how microplastics interact with salt-stressed soils and found that microplastics reduced water flow and total evaporation while also suppressing the formation of desiccation cracks, with effects varying by microplastic concentration and soil salinity. These findings reveal that microplastic pollution can meaningfully alter the water and structural behavior of agricultural soils already under stress from salinization.
Irrigation of reclaimed water leads to the accumulation and potential risk of microplastics in saline-alkali soil
In the arid agricultural regions of western China where reclaimed wastewater is used for irrigation, this study found that even after 87.5% of microplastics are removed during treatment, the remaining particles accumulate in soils over time — primarily as small polypropylene and polyamide fragments. Although current ecological risk scores are technically low, the study highlights a fundamental trade-off: using treated wastewater to solve water scarcity introduces a slow but steady buildup of microplastic contamination into the food-growing soils that feed local communities.
