Summary

This field and laboratory study examined the in situ degradation behaviour of biodegradable plastic mulch films under realistic agricultural conditions and in compost. Drawing on expertise from major land-grant universities, the work provides empirical evidence on whether such films biodegrade within practical farming timescales and assesses implications for soil health and the sustainability of this increasingly adopted horticultural input.

UK applicability

The findings are relevant to UK horticultural practice, particularly for soft fruit and vegetable production where plastic mulch adoption is growing. However, UK soil conditions, temperature regimes, and moisture patterns differ from United States sites; application of degradation timelines should account for cooler, wetter growing seasons typical of the UK.

Key measures

Film degradation rates (mass loss over time), residual film fragments, chemical composition changes, degradation timelines in soil and compost environments

Outcomes reported

The study assessed the rate and extent of degradation of biodegradable plastic mulch films under field and laboratory conditions in agricultural soils and compost environments. It measured physical and chemical breakdown of mulch films over time to determine whether they biodegrade within realistic agricultural timescales.
