Impacts of Biodegradable Mulch: Benefits, Degradation, and Residue Effects on Soil Properties and Plant Growth

Abstract

Biodegradable mulch is gaining popularity as a sustainable replacement for conventional plastic mulch because it can fully degrade in the soil, making it more environmentally friendly. However, uncertainties remain regarding its in-situ degradation under diverse natural conditions and over prolonged durations. Furthermore, questions persist about the long-term environmental impact of biodegradable mulch usage on plant–soil health. This review focuses on the use of plastic mulch in agriculture, including its benefits, application across climates, degradation characteristics, and the impact of plastic mulch residues on soil properties and plant growth.
