The Invisible White Micropollutants of Green Agriculture: 10 Essential Scientific Questions for the Future of Agricultural Microplastic Research

To identify critical knowledge gaps and define strategic research priorities for microplastic and nanoplastic contamination in agricultural soils. Current evidence on agricultural microplastics was critically synthesized, with emphasis on analytical methodologies, environmental fate, ecological effects, plant uptake, food‐chain transfer, and remediation approaches. Key knowledge gaps were evaluated to formulate priority research questions. Ten essential scientific questions were identified, spanning four thematic areas: extraction and quantification, environmental realism and ecosystem effects, plastic–pollutant–microbe interactions, and crop uptake, human exposure, and mitigation strategies. Major challenges include the lack of standardized analytical protocols, limited understanding of long‐term environmental behavior and biological impacts, uncertainties regarding biodegradable plastics, and the absence of scalable remediation technologies. Future agricultural microplastic research should move beyond contamination surveys toward mechanistic understanding, predictive assessment, and field‐validated mitigation strategies. Addressing these priorities is critical for protecting soil health, food security, and environmental sustainability.
