This report examines how plastic pollution affects agricultural soils, showing that even low concentrations alter physical, chemical and microbiological properties. These changes disrupt soil structure, water retention, nutrient cycles and microbial communities, threatening plant health, crop yields and food quality.
The report also raises concerns about plastics and associated chemicals entering plants and livestock, with potential food safety risks. It identifies major knowledge gaps, particularly on the long-term impacts of agricultural plastics, the behavior of micro- and nanoplastics and the safety of biodegradable alternatives.
By mapping current evidence and uncertainties, this resource provides a foundation for shifting policies, practices and investments towards sustainable solutions that protect ecosystems, human health and food security.
