Summary
This long-term field study examines whether biodegradable mulch films, promoted as sustainable alternatives to conventional polyethylene, generate microplastic fragments during soil degradation that compromise soil microbial function and nutrient cycling. The research quantifies both agronomic benefits and environmental trade-offs, addressing whether such films represent genuine environmental improvement or shift contamination risk from macroplastic to microplastic forms. Findings contribute evidence-based guidance on sustainable mulching practices in horticulture.
UK applicability
UK horticultural systems increasingly adopt biodegradable mulch films to meet environmental targets. These findings are directly relevant to UK policy on sustainable agriculture and soil health, particularly for growers balancing yield maintenance with pollution reduction.
Key measures
Microplastic particle abundance and size distribution in soil; soil microbial activity and community composition; soil nutrient cycling rates; agronomic performance metrics (as suggested by title and journal scope)
Outcomes reported
The study quantified microplastic fragment generation during long-term field degradation of biodegradable mulch films and assessed impacts on soil microbial community function and nutrient cycling processes.
