The benefits varied by precipitation level, fertilizer application, and mulching method, providing guidance for optimizing this widely used agricultural practice.
Polymer Coated Urea in ‘Russet Burbank’ Potato: Yield and Tuber Quality
Researchers evaluated polymer coated urea (PCU) as a nitrogen fertilizer for Russet Burbank potato production at three Idaho locations, comparing PCU applied at emergence, conventional urea at emergence, and split-applied urea across five nitrogen rates. PCU-fertilized treatments produced 10-11% higher marketable and total tuber yields compared to conventional urea applications, demonstrating PCU's potential to improve nitrogen use efficiency in potato production.

Straw Return with Biodegradable Film Mulch: A Synergistic Cultivation Measure with Environmental and Economic Benefits Based on Life Cycle Assessment
Researchers used life cycle assessment to evaluate straw return combined with biodegradable plastic film mulch as a cultivation strategy for Chinese farmland, comparing environmental and economic outcomes against conventional practices.

Spatiotemporally Matched Nitrogen Release from a Double Core-Shell Urea Improves Rice Growth
Researchers evaluated a novel double core-shell controlled-release urea fertilizer designed to match the biphasic nitrogen uptake pattern of rice plants. Over a two-year field experiment, the fertilizer delivered two distinct nitrogen release peaks aligned with vegetative and reproductive growth stages, improving photosynthetic efficiency and grain yield. The study suggests this approach could reduce nitrogen fertilizer input by nearly 17% without compromising rice yields.
Degradable film mulching increases soil carbon sequestration in major Chinese dryland agroecosystems
Researchers compared biodegradable and conventional plastic film mulches used in farming and found that biodegradable films increased carbon storage in soil while traditional plastic mulch reduced it, suggesting that switching to biodegradable alternatives could help fight climate change while cutting plastic pollution.
Effects of Biodegradable Film and Polyethylene Film Residues on Soil Moisture and Maize Productivity in Dryland
Researchers found that biodegradable agricultural films are a viable alternative to conventional polyethylene mulch films, with higher degradation rates and less impact on soil moisture and maize root growth, ultimately improving grain yield and water use efficiency over a two-year field experiment.
Crop Management System Consisting of Biodegradable Mulching Film + Drip Irrigation Increases Yield and Quality of Flue-Cured Tobacco
This paper is not about microplastics; it compares biodegradable plastic mulching film combined with drip irrigation against conventional bare-soil and sprinkler irrigation for tobacco crops, focusing on yield and quality outcomes.
Enhancing carbon restoration and ecosystem resilience in global drylands via water-to-carbon biotransformation strategies
Researchers synthesized thousands of experiments on dryland farming and found that combining crop diversification, efficient irrigation, soil mulching, and soil health practices can significantly restore carbon to depleted soils while improving water use efficiency. The study argues these strategies are practical pathways for combating climate change and food insecurity in the world's most water-stressed regions.
Optimized Farmland Mulching Improves Rainfed Maize Productivity by Regulating Soil Temperature and Phenology on the Loess Plateau in China
A field experiment on the Loess Plateau found that combining plastic film mulch with straw mulch regulated soil temperature and extended the grain-filling period of rainfed maize, preventing premature senescence and improving yields. The study highlights a trade-off in dryland agriculture: plastic mulch conserves moisture but overheats soil, while novel double-mulching patterns can mitigate the temperature problem while still relying on plastic film.
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.
Impact of Management Strategies on Reducing of Mulching Film Residues Pollution in Arid Regions
Researchers examined the impact of different management strategies — including increased polyethylene film recycling rates and adoption of biodegradable mulch films — on reducing mulching film residue pollution in arid agricultural regions. The study found that combining recycling incentives with biodegradable film adoption significantly reduced soil plastic accumulation, supporting sustainable agricultural development in water-limited dryland farming systems.

Liming promotes the leaching of carbon and nitrogen in a double-cropped rice system
Researchers tested the effects of adding lime to acidic rice paddies and found that while liming boosted grain yields by about 12%, it also significantly increased the leaching of dissolved nitrogen and carbon compounds into groundwater, particularly during early growth stages. The findings suggest that lime application needs to be paired with practices that protect groundwater quality.
