ClearRecent advances on iron bound phosphorus in wetland sediments: characteristics, influencing factors, interactions with organic matter and emerging contaminants
This review synthesizes global data on iron-bound phosphorus in wetland sediments, examining how redox-driven dissolution cycles control phosphorus bioavailability and how emerging contaminants like microplastics interact with iron-phosphorus dynamics in these ecosystems.
A Comparison of Rice Root Microbial Dynamics in Organic and Conventional Paddy Fields
Researchers compared the root-associated microbial communities of rice plants grown in organic versus conventional paddy fields across different growth stages. They found that organic farming supported more dynamic and diverse microbial communities, including beneficial methane-oxidizing and nitrogen-fixing bacteria at key growth stages. The study suggests that agricultural management practices significantly shape the microbial partners that support rice plant health and nutrient uptake throughout the growing season.
Dataset for: Fe oxides control the vulnerability of paddy soils to microplastic-induced carbon loss
This study found that iron compounds in rice paddy soil help protect against carbon loss when tiny plastic particles (microplastics) are present. When these iron compounds are lacking, microplastics can cause more carbon to escape from the soil as CO2 gas. This matters because healthy soil carbon storage is important for growing nutritious food and fighting climate change, but microplastics from pollution could be disrupting this natural process.
Dataset for: Fe oxides control the vulnerability of paddy soils to microplastic-induced carbon loss
This research found that iron compounds in rice paddy soil help protect against carbon loss when tiny plastic particles (microplastics) are present. When these iron compounds are low, microplastics cause more soil carbon to escape as CO2 gas, which could worsen climate change. This matters because microplastics are increasingly common in agricultural soils from plastic pollution, and healthy soils are crucial for growing food and storing carbon.
Microplastics Modulate Carbon Sequestration in Paddy Fields by Regulating Rhizosphere Silicon Mobility
Microplastics were found to modulate carbon sequestration in paddy fields by altering microbial activity and organic matter decomposition rates. The study highlights that plastic contamination in rice paddies can disrupt the carbon cycle, potentially offsetting the carbon storage capacity of these ecosystems.

Researchers used culturomics and amplicon-based metagenomics to characterise bacterial communities in rhizosphere and bulk soils of high-yield Oryza sativa japonica paddy fields, identifying the microorganisms contributing to rice growth adaptability. The combined approach revealed the taxonomic composition and functional potential of the bacterial community in the paddy field agroecosystem.
Divergent mechanisms of labile phosphorus accumulation in paddy soils under TPU microplastics versus manure-derived hydrochar: roles of dissolved organic matter and bacterial communities
Scientists found that tiny plastic particles and a charcoal-like material called hydrochar can increase the amount of phosphorus available to rice plants in soil by 14-21%. Both materials work by changing the soil's chemistry and the helpful bacteria that live in it, but they do it in different ways. This matters because phosphorus is essential for growing healthy crops, and understanding how plastic pollution affects soil could help farmers maintain productive rice fields.
Microplastics shape microbial communities affecting soil organic matter decomposition in paddy soil
Researchers found that microplastics shape soil microbial communities in paddy soils in ways that affect organic matter decomposition, revealing how bacterial succession and carbon cycling are altered by microplastic presence in agricultural systems.
Dynamic production of hydroxy radicals affects the available Cadmium in paddy soils under microplastic contamination
Researchers showed that polyethylene microplastics amplify hydroxyl radical production in flooded paddy soils through photochemical activation of plastic-derived dissolved organic carbon and iron cycling, raising plant-available cadmium concentrations by up to 4.5-fold and highlighting a previously overlooked mechanism by which microplastics worsen heavy metal contamination in rice fields.
Susceptibility of Cd availability in microplastics contaminated paddy soil: Influence of ferric minerals and sulfate reduction
When microplastics and cadmium contaminate paddy soil together — a common situation in agricultural areas — microplastics increase the availability of cadmium to plants, raising the risk of cadmium uptake into food crops like rice. The mechanism involves microplastics releasing dissolved organic matter that disrupts iron mineral cycling and promotes sulfate-reducing bacteria, which in turn mobilize cadmium from soil particles. These findings highlight that microplastic pollution in farmland does not act alone — it can amplify the toxicity of co-occurring heavy metal contaminants.
Fe-modified biochar-driven ROS generation in the rhizosphere and their role in microplastic transformation
Researchers found that iron-modified biochar generates reactive oxygen species in paddy soil rhizospheres, and that these ROS interact with microplastic contamination to influence soil biogeochemical cycling in ways that differ from unmodified biochar.
In-Depth Insights into the Complex Interplay Between Microbial Diversity, Ecological Functionality, and Soil Health in Rice Agroecosystems
This review paper summarizes existing research on tiny organisms (microbes) that live in rice paddies and how they affect the rice we eat. Scientists found that these microbes play important roles in rice farming - they help break down plant waste, control harmful gases like methane, and can influence whether rice contains dangerous toxins or beneficial nutrients. The research suggests that farmers could manage these microbes better to grow healthier rice while protecting the environment, but more studies are needed to make this practical.

High temperatures and microplastic enhanced inorganic phosphorus mineralization and phoD-harboring bacterial abundance in paddy soil
Researchers studied how microplastic contamination in rice paddy soil interacts with high temperatures to alter nutrient cycling and soil bacteria. They found that at normal temperatures microplastics reduced key soil nutrients, but at elevated temperatures the effect reversed, actually increasing nutrient availability and microbial diversity. The findings suggest that climate change could amplify the ways microplastics disrupt agricultural soil ecosystems.
Molecular Insights into the Synergistic Inhibition of Microplastics-Derived Dissolved Organic Matter and Anions on the Transformation of Ferrihydrite
Researchers investigated how dissolved organic matter released from microplastics combines with naturally occurring ions to affect iron mineral transformations in the environment. They found that microplastic-derived organic matter and ions like phosphate work together to strongly inhibit the conversion of a reactive iron mineral called ferrihydrite. The findings matter because these iron minerals play key roles in nutrient cycling and pollutant fate in soils and waterways.
Nano iron oxide closes the gap between climate regulation and food security trade-offs
This study found that applying nano iron oxide to rice paddies can reduce greenhouse gas emissions while maintaining crop yields. Agricultural management practices that reduce environmental footprint are relevant given that plastic mulches and agrochemicals also contribute to microplastic soil contamination.
Redox-induced transformation of potentially toxic elements with organic carbon in soil
This review examines how soil organic carbon drives chemical transformations of potentially toxic elements like chromium, arsenic, and thallium through redox reactions. The study highlights that organic carbon's rich redox-active functional groups can both mobilize and immobilize toxic elements depending on conditions, providing important insights for soil remediation strategies.
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.
